	    Mathiue Suen  <mathieusuen@yahoo.fr>

	* libgst/dict.inl: Fix 32-bit #int and 64-bit #uint limits.

2010-12-05  Paolo Bonzini  <bonzini@gnu.org>

	* lib-src/sockets.c: Use O_NONBLOCK from socketx.h.

2010-12-04  Paolo Bonzini <bonzini@gnu.org>

	* libgst/memzero.h: Remove.
	* libgst/dict.c: Replace memzero with memset.

	global directly.  Also, _gst_nil_oop is kept in a register so
	icache-wise it pays to always do the store into parentContext.

2010-11-08  Paolo Bonzini <bonzini@gnu.org>

	* libgst/dict.inl: Add instantiate_numbytes, use it for instantiate
	and non-pointer instantiate_with; do not unroll nil initialization
	since N is usually small here.  Rewrite nil_fill.

	* libgst/prims.def: Likewise.  Remove duplicate checks.

2010-07-27  Paolo Bonzini <bonzini@gnu.org>

	* libgst/sysdep.h: Remove _gst_full_write.
	* libgst/sysdep/common/files.c: Move _gst_full_write...
	* libgst/save.c: ... here.  longjmp out to _gst_save_to_file when
	it fails.

2010-07-27  Paolo Bonzini <bonzini@gnu.org>

	* libgst/cint.c: Fix warnings.
	* libgst/real.c: Fix out-of-bounds array access (which is actually

	system calls to avoid EFAULT.

2010-06-06  Paolo Bonzini <bonzini@gnu.org>

	* libgst/sysdep/posix/time.c: Fix previous change for millisecond
	vs. microsecond confusion.

2010-05-28  Paolo Bonzini <bonzini@gnu.org>

        * libgst/events.c: Avoid infinite loop.

2006-12-28  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/dict.c: Change _gst_init_dictionary_on_image_load to be

	the default primitive table just like in _gst_init_dictionary.
	* libgst/dict.h: Adjust for above change.
	* libgst/genpr-parse.y: Compute MD5 of DEF_FIL as checksum and
	print it.
	* libgst/interp.h: Declare _gst_primitives_md5.

	to load_file_version.

2006-12-28  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/gstpriv.h: Remove F_FREE.
	* libgst/oop.c: Remove loops setting flags to F_FREE.  Set flags to 0

	structs (instead of pointers).
	* libgst/opt.c: Likewise.
	* libgst/sym.c: Likewise.
	* libgst/vm.def: Use _gst_builtin_selectors instead of symbols
	defined in sym.c (not slower with the change above).
	* libgst/xlat.c: Only store the opcode in special_send_bytecodes and
	use _gst_builtin_selectors for the other pieces of information.

	* libgst/dict.c: Don't reload the _gst_*_class variables unless
	necessary.  Pass the class to identity_dictionary_new and adjust the
	sole caller, _gst_valid_class_method_dictionary.  Split the
	creation of symbols in two parts (creating symbols, and populating
	the symbol table with SymLink objects); call _gst_restore_symbols
	when loading the image.  Remove _gst_directed_message_new_args.
	* libgst/interp.c: Remove commented out code to start call-ins through
	Process>>#startExecution:.

	* libgst/gstpriv.h: Reserve three less bits to runtime flags, add
	F_LOADED.
	* libgst/oop.c: The address of loaded objects never changes, and
	they're always old.  Never compact loaded objects.  Never free them too.
	* libgst/print.c: Print loaded OOPs correctly.
	* libgst/save.c: Define and use buffer_advance.  Try reusing the
	mmap-ed area in load_normal_oops; free buffer in load_normal_oops
	only if copy-on-write is not used.  Mmap all the file in a
	single step, and using MAP_PRIVATE, and only do the "read" method
	in buffer_fill.  Rename use_mmap to buf_used_mmap.  Save objects with
	the old bit set and without the F_RUNTIME flags.

2006-12-22  Paolo Bonzini  <bonzini@gnu.org>

2006-12-21  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/lex.c: Build strings on obstack instead of the
	str.c buffer.  Otherwise the buffer could be cleared out

	* libgst/str.c: Remove dead functions.
	* libgst/str.h: Likewise.

2006-12-19  Paolo Bonzini  <bonzini@gnu.org>

	allocation granularity.

2006-12-15  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/save.c: Store object table base in the image, adjust based
	on the delta upon loading.  Inline functions that are not used
	anymore upon saving due to the previous change.  Reset nativeIP
	upon saving rather than upon loading.

2006-12-14  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/cint.c: Move gst_cfunc_descriptor to cint.h.  Accept a nil
	cFunction inside a descriptor (now happens upon image load),
	remove _gst_restore_cfunc_descriptor.
	* libgst/cint.h: Adjust for cint.c changes.
	* libgst/comp.c: Remove _gst_restore_primitive_number.
	* libgst/comp.h: Remove _gst_restore_primitive_number.
	* libgst/dict.c: Initialize primitive table from default in
	_gst_init_dictionary, and from the image in prepare_primitives_table	
	(which replaces prepare_primitive_numbers_map).  Don't reset
	the VMPrimitives dictionary upon image load, and don't walk the
	OOP table.
	* libgst/genpr-parse.y: Initialize _gst_default_primitive_table
	instead of _gst_primitive_table.
	* libgst/interp.c: Use _gst_default_primitive_table in
	_gst_get_primitive_attributes, add _gst_set_primitive_attributes.
	Make the primitive tables public.
	* libgst/interp.h: Adjust for the above.
	* libgst/save.c: Allocate temporary storage for the object that
	are about to be saved.  Massage the CallinProcess, Process,
	Semaphore and CFunctionDescriptor instances in that temporary
	storage rather than at load time.

2006-12-14  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/input.c: Initialize completions only when a readline stream
	is pushed.

2006-12-12  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/oop.c: Proceed recursively if marking the ephemerons'
	slots finds more ephemerons.  Add more debugging functions.
	Rename GC_DEBUGGING and MMAN_DEBUGGING to GC_DEBUG_OUTPUT and
	MMAN_DEBUG_OUTPUT.  Preprocessor symbol GC_DEBUGGING now enables
	sanity checks.

	* libgst/prims.inl: Primitive 90, instead of returning the
	native code for a method, discards the method (completely
	different semantics -- but the old one had no use since
	the Smalltalk program had no interesting use of the result).

2000-09-09  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/byte.c: Modified bytecode 134 for pop-into-array

	programming mania).

2000-08-06  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/byte.c: Moved part to opt.c
	* libgst/byte.h: Moved part to opt.h
	* libgst/opt.c: Created from byte.c.  As the JIT compiler will
	get more sophisticated this part is going to get bigger.
	* libgst/opt.h: Created from byte.h

	* libgst/comp.c: Include opt.h.  Also, don't generate unreachable
	jumps in `... ifTrue: [ ^true ]' (or an analogous pattern with
	#ifTrue:ifFalse:).  This pleases computeStackPositions enough
	to run the Prolog and Lisp interpreters.
	* libgst/xlat.c: Include opt.h

	* libgst/gst.h: Added F_FIXED.
	* libgst/oop.h: Declared makeFixedOOP.
	* libgst/oop.c: Added makeFixedOOP, deal with fixed objects
	in prepareForSweep.
	* libgst/prims.inl: Added primitive 170-172 to deal with fixed
	objects.
	* libgst/save.c: Always clear F_RUNTIME flags, not only when
	the endianness is wrong!!! This caused the GC to try to release
	the native code version of methods that had indeed been compiled
	when the image was saved, but were not compiled when GC was
	invoked.  Also implemented saving F_FIXED objects.

2000-07-10  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/lib.c: Allow usage of Undeclared in the kernel's source

2000-07-04  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/oop.c: In gcFlip, modify numFreeOOPs so that allocOOPs
	allocates its OOPs merrily, even if we're below the low-water
	threshold.
	* libgst/oop.h: Defined LOW_WATER_OOP_THRESHOLD
	* libgst/oop.inl: In allocOOP, check low-water condition by
	looking at numFreeOOPs, not firstFreeOOP.

2000-07-02  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/gst.y: Add `oval' to the union, and define (and parse)

	* libgst/tree.h: Declared makeOOPConstant

2000-07-01  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/interp.c: Don't overwrite the method cache until we
	are sure that the receiver understands the message (lookupMethod)
	* libgst/lib.c: Load AnsiDates.st and ScaledDec.st too
	* libgst/prims.inl: Handle case where the receiver is a `Float'
	but the argument is a `SmallInteger' directly in the 41-to-50
	primitives.
	* libgst/xlat.c: Another fix to the strength-reduced division
	algorithm.  If adjust is true, fixing the dividend if the signs
	mismatch produces an incorrect result.

2000-06-26  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/prims.inl: Restored divide-by-zero check in //, \\ and
	/ (removed by mistake June 21st)

	* libgst/xlat.c: Removed interrupt check from the method prolog,
	moved it to the `return' bytecodes and to after a primitive;
	this fixed processes.
	Also INLINED_CONDITIONAL now adjusts the stack top in V2 and then
	resets spDelta instead of simply decrementing spDelta: this
	caused incorrect compilation of #ifTrue:ifFalse: if the receiver
	was inlined and the returned value was used as a parameter to a
	message.  There are no regressions with respect to the bytecode
	interpreter now.

2000-06-21  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/comp.c: When compiling a #repeat loop, add a dummy
	`push nil' bytecode at the end to please the JIT compiler
	(which said its stack had underflowed -- it was right, but it
	was compiling unreachable code...).
	* libgst/interp.h: Made the primitiveTable `const'
	* libgst/interp-bc.inl: Use primitives for //, \\ and / if both
	arguments are integers
	* libgst/interp-jit.inl: First fixes to add processes to the JIT
	compiler
	* libgst/prims.inl: Fixed meaning of // and \\ for negative divisors;
	in primitive 90, use getReturnIP (defined in interp-jit.inl).
	* libgst/xlat.c: Fixed meaning of // and \\ for negative divisors;
	fixed overflow detection in multiplication; align interrupt checks
	to 4 bytes.

2000-06-18  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/dict.c: Added to SortedCollection two instance variables
	needed to be able to amortize sorting cost (through heaps & merging).

2000-06-17  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/xlat.c: Fixed doesNotUnderstand

2000-06-17  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/byte.c: Fixed bug in optimizeByteCodes (|| was there
	instead of &&) which upset the JIT compiler
	* libgst/comp.c: If a method is a primitive return of a
	BlockClosure, initialize the BlockClosure in methodNew.

	* libgst/oop.c: Call releaseNativeCode instead of
	freeNativeCode in prepareForSweep, at the end call
	freeNativeCode
	* libgst/xlat.c: Removed definition of MethodEntry, renamed
	freeNativeCode to releaseNativeCode, added freeNativeCode
	* libgst/xlat.h: Added definition of MethodEntry, declared
	releaseNativeCode
	* libgst/interp.h: Declare validateMethodCacheEntries
	* libgst/interp-bc.inl: Added validateMethodCacheEntries (no-op)

2000-06-07  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/interp.c: Fixed behavior of emptyContextStack with
	regard to the returnIP field.
	* libgst/interp-jit.inl: Don't look at the header flag in

	Still missing: processes, doesNotUnderstand:

2000-06-06  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/prims.inl: Use a huge table of functions instead of
	a huge switch statement
	* libgst/interp.h: Declare table of functions for
	the primitives

	if the method has no arguments and no temporaries.  Plus,
	use computeStackPositions.

2000-06-03  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/xlat.c: Support #valueWithArguments: and other
	primitives (other than 81) which use sendBlockValue.  Wrote
	the code for compiling deferred sends.  Working inlined
	comparisons.

	* libgst/prims.inl: Added primitive 90 to retrieve the
	native code for a method.

2000-06-02  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/comp.c: If USE_JIT_TRANSLATION is defined,
	executeStatements skips some values which aren't mantained in
	that case.

	* libgst/xlat.c: Fixed error in pushing thisContext (wrong
	register used, R1 instead of V1).  Fixed problems when the
	stack was empty in setTopNodeExtra.  The method hash table
	was broken -- did not initialize current->receiverClass.
	Also check in the block's prolog, if code for the right
	CompiledBlock is being executed.

	* libgst/interp-jit.inl: Reset the exceptFlag after execution
	of JIT-compiled native code is interrupted.  The interpreter
	is now able to create an image and then restore it.

2000-05-29  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/xlat.c: Added some inlining (==, isNil, notNil,
	blockCopy:); modified suboperation codes so that `2' is reserved
	to literals (which aids a lot when inlining).  Blocks done, they
	were easy.

2000-05-28  Paolo Bonzini  <bonzini@gnu.org>

	* libgst/comp.c: Moved here a ChangeLog comment that actually
	described the code; gave a category to Behavior>>#methodsFor:

	* libgst/xlat.c: Usual tons of fixes.  Crashes at initialize.st.
	Among others:
	- save the returnIP in the parent context, not in the newly created
	  context (that is before activateNewContext rather than afterwards).
	- fixed the method prolog to update the `self' variable, which I had
	  forgotten
	- labels did not work (had missed a *)
	- do EXPORT_SP_CODE in crucial points, including basic block boundaries

	* libgst/interp.c: New procedure showStackContents
	* libgst/interp.h: Declared showStackContents
	* libgst/prims.inl: Use showStackContents in the temporary definition
	of #error: and #doesNotUnderstand: (useful for debugging)

	added getContextIP & setThisMethod
	* lib/interp-bc.inl: Moved unwindContext and changeProcessContext
	back to interp.c, added getContextIP
	* lib/interp.c: Restored unwindContext and changeProcessContext from
	interp-bc.inl, used getContextIP instead of toInt(...->ipOffset)
	* lib/oop.c: Implemented a `second chance' algorithm for disposing
	of methods whose native code translations are not referenced by any
	context.

	expression was `i', now is `*i').  Caused SIGSEGV when a missing
	library name was passed.

2000-02-01  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.h: Subsumed bytecodes 132 and 134 (a whole byte for
	the argument count is way too much, and it does not matter if
	it's a bit slower because these bytecodes are rare indeed).
	* lib/byte.c: Print bytecode 132 according to the new coding
	* lib/bytecode.inl: Interpret new coding for bytecode 132
	* lib/comp.c: Emit new coding for bytecode 132

2000-01-31  Paolo Bonzini  <bonzini@gnu.org>

	*** Sixth beta of 1.7 (labeled 1.6.85) released

2000-01-31  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Worked out bugs in call-ins that were added
	after the introduction of the `terminate interpreter' bytecode
	(Jan 8th) and which prevented Blox from working.
	prepareExecutionEnvironment was stacking a context with an OOP
	from the main OOP table over some lifoContexts.
	* lib/oop.c: Moved debug() to sysdep.c
	* lib/oop.h: Moved debug() to sysdep.h
	* lib/sysdep.c: Moved debug() here from oop.c
	* lib/sysdep.h: Moved debug() here from oop.h

2000-01-28  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Fixed bug with double-freeing of block bytecodes
	(this is also due to a very permissive allocator)
	* lib/lex.c: Fixed bug in parsePrimitive (xfree without matching
	xmalloc) -- strangely enough, it didn't show up on all systems!
	* lib/prims.inl: Fixed Memory primitives to return and accept
	LargeIntegers for addresses when needed.

2000-01-24  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: Changed the clean block detection machinery to work
	with CompiledBlocks.  Previously, we emitted a fixed sequence of
	bytecodes for blocks, then we made a pass on the bytecodes before
	optimization patching already generated code in case we found the
	block to be clean.  Now, instead, we compute information on the
	block's cleanness before we create the CompiledBlock object, we
	embed the information in the CompiledBlock's header, and then use
	that information to directly emit optimized bytecodes in case the
	block is clean (instead of applying patches later).
	* lib/comp.c: Moved `class' and `selector' fields to MethodInfo.
	Blocks are compiled to CompiledBlocks.
	* lib/comp.h: Removed `class' and `selector' fields from [Compiled]Method
	* lib/dict.c: New definitions of MethodInfo, CompiledCode, CompiledMethod,
	CompiledBlock; declaration of compiledCodeClass and compiledBlockClass.
	* lib/dict.h: Declaration of compiledCodeClass and compiledBlockClass
	* lib/interp.c: Execute blocks from CompiledBlocks.
	* lib/lib.c: Load CompildCode.st and CompiledBlk.st
	* lib/prims.inl: Added primitive 68 to create CompiledBlocks.

2000-01-20  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: Fixed crash on methods whose last act was
	returning a clean block.  It turned out that evaluating those
	blocks was GST's last act, either...
	* lib/cint.c: Enable passing 32-bit LargeIntegers in C call-
	outs.  Looks like I had forgotten about it on Sep 10 1999.
	Also, introduced a `pVoidFunc' typedef to avoid Lisp-like
	abundance of parentheses when passing C function addresses.

2000-01-20  Paolo Bonzini  <bonzini@gnu.org>

	* lib/bytecode.inl: IntegerClass -> smallIntegerClass
	* lib/dict.c: IntegerClass -> smallIntegerClass, plus
	added definition of SmallInteger
	* lib/dict.h: Added declaration of SmallInteger
	* lib/gst.h: IntegerClass -> smallIntegerClass
	* lib/interp.c: IntegerClass -> smallIntegerClass
	* lib/interp.inl: IntegerClass -> smallIntegerClass
	* lib/lib.c: Load SmallInt.st too.
	* lib/prims.inl: IntegerClass -> smallIntegerClass

2000-01-15  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Adapted large integer compilation stuff in
	makeConstantOOP to compile ByteArrays too.
	* lib/gst.y: Added rules for ByteArray literals and arrays
	like #(1 2 3 #(4 5 6)) -- i.e. with the sharp inside the
	parentheses
	* lib/lex.c: Make parseNumber return BYTE_LITERAL for
	integers between 0 and 255
	* lib/tree.c: Added makeByteArrayConstant

2000-01-09  Paolo Bonzini  <bonzini@gnu.org>

	* lib/lex.c: CurStrBuf -> obstack_curStrBuf; plus, added
	the compilationObstack variable which is initialized in
	parseStream.
	* lib/lex.h: Added declaration of compilationObstack
	* lib/str.c: Added obstack_curStrBuf
	* lib/str.h: Declared obstack_curStrBuf
	* lib/tree.c: Heavily simplified destruction code by using
	obstacks

	* lib/lib.c: Solved SIGSEGV when gst.im was not in the
	current directory and SMALLTALK_IMAGE was not set.

2000-01-09  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Added code to create Smalltalk LargeInteger
	objects from large integer ConstNodes in makeConstantOOP.
	* lib/gst.y: Handle large integer literals in the grammar
	* lib/lex.c: Added code to parse large integer literals
	* lib/tree.c: Added code to create large integer ConstNodes
	* lib/tree.h: Added declaration of the LargeInteger struct
	and of large integer ConstNodes

2000-01-08  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.h: Added `exitInterpreter' bytecode.
	* lib/comp.h: Declared `getTerminationMethod'.
	* lib/comp.c: Implemented `getTerminationMethod', and added code
	to installInitialMethods which installs a termination method
	which executes the new bytecode above.
	* lib/bytecode.inl: Implemented `exitInterpreter' bytecode.
	* lib/interp.c: Contexts created by prepareExecutionEnvironment
	no longer have to be special cased in unwindLastContext.
	* lib/sym.c: Added terminateSymbol.
	* lib/sym.h: Added terminateSymbol.

2000-01-02  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Gst enters the new millennium!!! (yeah, I know it
	actually starts in 2001 but I don't want to wait another year... ;-)
	and it does by getting rid of the free lists for contexts -- it is
	faster to use the memory chunks like a stack.
	Also, I replaced tests for `isNil(thisContextOOP)' with tests for
	`!ip'.
	
	* lib/strerror.c: Added.
	* lib/sysdep.c: Win32 implementation of getMilliTime now more precise
	* lib/sysdep.h: Added macros for frexp and ldexp where they aren't
	available
	 
1999-12-28  Paolo Bonzini  <bonzini@gnu.org>

	*** Fifth beta of 1.7 (labeled 1.6.84) released

	* lib/byte.c: New functions checkKindOfBlock and patchCleanBlocks.
	* lib/byte.h: Declaration of patchCleanBlocks.

1999-12-27  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: New function fixupBlockClosures.
	* lib/comp.c: New way of compiling blocks.
	* lib/bytecode.inl: Bytecode 200 is now #blockCopy: (same as the Blue
	Book, but the primitive is implemented differently of course).
	* lib/prims.inl: New implementation of primitive 80 (blockCopy)
	* lib/sym.c: Removed #blockCopy:temporaries: (replaced with #blockCopy:),
	added machinery to reveal `clean' blocks
	* lib/sym.h: Removed #blockCopy:temporaries: (replaced with #blockCopy:)

1999-12-27  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Added method to BlockClosure, changed to new
	context structure (methodClass/selector retrieved from the
	compiledMethod, method only there for MethodContexts)
	* lib/interp.c: Changed to new context and BlockClosure structure
	* lib/prims.inl: Changed to new BlockClosure structure

1999-12-26  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Store the class and selector in the created
	CompiledMethods.  A first step towards leaner context objects
	(i.e. more speed when sending messages!) and more powerful
	constructs such as `clean' block closures (which do not need
	to be created at run-time because are isolated from the outer
	contexts).
	* lib/comp.h: Added `class' and `selector' to struct Method.
	* lib/dict.c: Added `class' and `selector' to CompiledMethod.
	* lib/prims.inl: Pass class and selector to makeNewMethod.

1999-12-19  Paolo Bonzini  <bonzini@gnu.org>

	* lib/bytecode.inl: Removed hasBlock (can be replaced with a
	test on whether the context lies in the main OOP table); this
	simplified both sends and returns.  I also made the structure
	of method and block context objects more similar, resulting
	in simpler and faster code (except for block returns), and
	opening doors to optimizations such as delayed filling of the
	`method' and `receiver' slots of context objects.  The overall 
	improvement obtained since the Dec 17 change amounts to 9-10%.
	* lib/dict.c: Same as above
	* lib/interp.c: Same as above
	* lib/interp.h: Same as above
	* lib/prims.inl: Same as above

1999-12-17  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Various changes, notably to getMethodContext and
	its users, to avoid using oopToObj more than once on the same
	object.

1999-12-17  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.h: Nil is now 0L (used to be 0), which is better when
	used as a pointer.
	* lib/interp.c: As long as we're sure that the execution order is
	LIFO (i.e. as long as no blocks are involved), allocate OOPs for
	the contexts outside of the main OOP table; this is because
	allocOOP is slower than picking a pre-built OOP out of a stack.
	This partly resembles the design of 1.1.5 (introduced Jan 1, 1991
	and modified Oct 18, 1998), but has the advantage that when a
	BlockClosure is created we only have to allocate the OOPs that we
	tried to avoid -- 1.1.5 copied the whole objects to the main heap,
	causing way too many GCs.

1999-12-16  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.h: F_FAKE --> F_POOLED, isFake --> isPooled
	* lib/interp.h: ResetFakeContexts --> emptyContextsPool
	* lib/interp.c: (de)allocFakeContext --> (de)allocPoolContext,
	fakeList --> contextPool, plus changes above
	* lib/oop.c: RealizeOOPs --> sweepPooledObjects, plus changes above

1999-12-15  Paolo Bonzini  <bonzini@gnu.org>

	* lib/sym.c: Modified hashString to reduce likeliness that
	hash be zero.

1999-12-14  Paolo Bonzini  <bonzini@gnu.org>

	* lib/bytecode.inl: Use the new procedures below
	* lib/comp.c: Allocated one more bit for the method flags.  If
	there is a primitive index, the flags are now 4 (used to be 0).
	* lib/interp.c: The old `returnWithValue' procedure was split in
	two, unwindToContext and unwindLastContext -- one is used upon an
	explicit `return from method', the other does less job and returns
	to the parent context upon a `return from context'

1999-12-11  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Moved findClassMethod here from lib/dict.inl
	* lib/dict.h: Restored declaration of findClassMethod
	* lib/dict.inl: Moved findClassMethod here to lib/dict.c -- it is
	used rarely (only for method cache misses) and was bloating
	sendMessageInternal's code.

	* lib/bytecode.inl: Simple one-byte bytecodes prefetch the next
	address to jump to (hoping to save address generation interlocks)
	* lib/interp.c: Support for prefetching

1999-12-06  Paolo Bonzini  <bonzini@gnu.org>

	* lib/bytecode.inl: Hard-code register allocation of ivar2
	and tempOOP only where they are actually used
	* lib/dict.inl: Hard-coded register allocation in nilFill
	* lib/interp.c: Hard-coded register allocation now relies on
	register.h and is used in sendMessageInternal/sendBlockValue.
	* lib/register.h: Created

1999-12-05  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: ReturnMethodStackTop became returnContextStackTop
	in isSimpleReturn.
	* lib/cint.c: Declare the strerror C function.
	* lib/gst.h: ANSI asks for 65535 instance variables, so I shifted
	the instance specification's `number of instance vars' field
	right by three bits (now 262143 variables are possible).
	* lib/lex.c: Parse stuff like 1.0d53 and 1.0q212 correctly even
	though FloatD/FloatE/FloatQ is not supported yet.

	* lib/memzero.h: Removed a conditional by using LONG_SHIFT in the
	generic version of memzero.

1999-12-05  Paolo Bonzini  <bonzini@gnu.org>

	* lib/bytecode.inl: The `hasBlock' instance variable in a context
	is now an integer (0 or 1).  This eliminated several lookups for
	the `trueOOP' and `falseOOP' globals.
	* lib/interp.c: Same as above
	* lib/prims.inl: Same as above

1999-11-26  Paolo Bonzini  <bonzini@gnu.org>

	*** Fourth beta of 1.7 (labeled 1.6.83) released

	* lib/bytecode.inl: Added caching of primitive numbers for sends of
	#at:, #at:put: and #size
	* lib/interp.c: Same as above
	* lib/prims.inl: Same as above

1999-11-22  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Fixed floating-point exception on operations
	with infinity and NaN, under FreeBSD.

1999-11-21  Paolo Bonzini  <bonzini@gnu.org>

	* lib/alloc.c: Use memzero instead of memset; also, xmalloc
	doesn't zero memory
	* lib/byte.c: Use memzero instead of memset
	* lib/dict.inl: Use memzero instead of memset
	* lib/dynamic.c: Use memzero instead of memset
	* lib/gst.h: Include memzero.h
	* lib/memzero.h: Added

	* lib/oop.c: Don't update numFreeOOPs on allocate/free oop.
	It is only used after a GC (to check whether the OOP table
	must be resized), so it is sufficient that it be correct
	after a GC.

1999-11-20  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: RestoreCFuncDescriptor was called at the wrong
	time in save.c -- before the xxxClass variables were loaded
	(Oct 20 change).  So now it is called here.
	* lib/save.c: See above for lib/dict.c

1999-11-20  P. Lecoanet

	* lib/bytecode.inl: Special case #blockCopy:temporaries: for
	context objects and #value/#value: for BlockClosure objects.
	Also, no need to push and pop the object for the `return
	self/true/false/nil' bytecodes -- a simple assignment will do.

1999-11-19  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Removed initNilVec and nilVec
	* lib/dict.inl: Implemented nilFill as an unrolled loop (memcpy
	is sloooow)
	* lib/interp.c: Arguments are moved between contexts with an
	unrolled loop (memcpy is sloooow); pushNNils now sets up the
	whole context stack (arguments+temporaries) and is called
	prepareContext.  Another +10% for this on send-heavy benchmark!!!

1999-11-18  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.h: ReturnBlockStackTop became returnContextStackTop
	* lib/comp.c: Compile returns from methods as returnContextStackTop
	(should be a bit faster)
	* lib/bytecode.inl: `return self' and other similar bytecodes
	fall into returnContextStackTop, not returnMethodStackTop.

1999-11-18  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Changed to account for removal of cacheHits and
	messagesSent.
	* lib/comp.h: Removed messagesSent.
	* lib/interp.c: Removed cacheHits and messagesSent, which 
	can be deducted from other statistics.
	* lib/interp.h: Removed cacheHits.
	* lib/prims.inl: New implementation of mutation does not need
	primitive 263 (#specialBasicAt:).

1999-11-17  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.inl: Access functions test subscript bounds -- this
	eliminates an instanceSpec lookup.
	* lib/prims.inl: No need to call checkIndexableBoundsOf on
	access primitives (#at:*, #basicAt:*)
	* lib/gst.y: Support for the #(1 2 3 #a #b #'cdef' 45) syntax
					     ^^ ^^ ^^^^^^^

1999-11-14  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: `return instance variable' stores index in the
	`primitive' field of the method header (allows more optimizations
	and better register allocation in sendMessageInternal)
	* lib/comp.h: Move flag bits to high end of the methodHeader, so
	that there is place for two additional bits if needed
	* lib/dict.c: BlockContexts now hold the receiver and the
	BlockClosure instead of the number of arguments and temporaries.
	* lib/interp.c: Same as comp.c and dict.c above; plus, removed
	code for ACCESSOR_DEBUGGING.
	* lib/interp.h: Same as dict.c above

1999-11-13  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: NilVec contains now 128 OOPs
	* lib/dict.inl: NilVec contains now 128 OOPs
	* lib/interp.c: Doc fixes; cleaned up unused variables in the code
	handling fake contexts; finally, the method cache now includes
	the method header (+5/10% performance).

1999-11-11  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dynamic.c: Move method whose threaded code representation
	is requested to the head of the methodsTable.
	* lib/lex.c: USE_MONCONTROL only affects the interpreter, not the
	lexer.
	* lib/lib.c: Disable execution tracing options when the dynamic
	translator is being used.
	* lib/oop.c: Removed code for ACCESSOR_DEBUGGING, which I found
	more bug-prone than useful in more than a year; added lines
	explaining GC_TORTURE.
	* lib/oop.inl: Removed the few lines that implemented the
	ACCESSOR_DEBUGGING preprocessor symbol and explained what it was
	for.

1999-11-10  Paolo Bonzini  <bonzini@gnu.org>

	* lib/bytecode.inl: In most bytecodes that are implemented with a
	switch statement, the switch statement is resolved at translation
	time.  Also, added `default' clauses to such switch statements so
	that the compiler can produce better code.
	* lib/dynamic.c: Same as above
	* lib/dynamic.h: Same as above
	* lib/interp.c: Same as above

	* lib/gst.h: Removed declarations of TreeNode, thisClass and
	regressionTesting, which are already declared elsewhere
	(respectively in tree.h, comp.h and lib.h).  Also removed
	declaration of Stream which is needed only in lex.c and is
	therefore moved there.
	* lib/lex.c: Moved declaration of Stream from gst.h

1999-11-09  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dynamic.c: Invalidating the macro opcode cache is now
	separated from invalidating the threaded code cache. Also,
	convert from threaded code ip to bytecode ip before 
	invalidating the threaded code cache; reload the methodBase 
	and the threaded ip after having invalidated it (in
	invalidateMethodCache). Everything works if no optimization 
	options are set when compiling.

1999-11-09  Paolo Bonzini  <bonzini@gnu.org>

	* lib/callin.c: SelectorNumArgs used; in addition, the result
	is checked to be the `nil' object in msgSendf is checked and,
	if so, 0 (or some variation of it, like 0.0 and NULL) is
	returned.
	* lib/interp.c: Added DEBUG_CODE_FLOW preprocessor symbol that
	prints every message that is sent in the same form used by
	backtraces (e.g. `Integer(Object)>>#retry:coercing:').
	* lib/prims.inl: SelectorNumArgs used in implementation
	of #perform:...
	* lib/sym.c: Added selectorNumArgs
	* lib/sym.h: Added selectorNumArgs

1999-11-08  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: Fixed bug in makeDestinationTable that caused
	macro-opcode inlining to lose as soon as a jump was found.
	* lib/dynamic.c: Had mistyped an = for an == grrr... 2 days to
	find it! Now runs up to WeakObjects.st both with and without
	macro-opcode inlining, so macro opcodes should be reasonably
	bug-free (except for problems arising from inlining code
	optimized by GCC, which I have not tackled yet).

1999-11-06  Paolo Bonzini  <bonzini@gnu.org>

	* lib/bytecode.inl: Jump bytecodes must be `PROTECT' bytecodes,
	isNil and notNil sends need not.  Found two unused variables.
	* lib/cint.c: Moved `extern' declaration of enableGC into cint.h,
	the actual declaration of the variable came here from interp.c
	* lib/cint.h: Moved `extern' declaration of enableGC from cint.c
	* lib/interp.c: Moved getMethodLiterals to interp.inl and
	enableGC to cint.c
	* lib/interp.inl: Moved getMethodLiterals from interp.c

1999-11-05  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: Can print bytecodes without a vector of literals
	* lib/dynamic.c: Added debugging support; offsetToFill was not reset
	when a non-inlinable opcode was found (fixed by setting it in
	newOpcodeEntry) -- now runs up to the first jump bytecode
	(#initialize in Character.st), or up to MethodDict.st
	with macro-opcode inlining disabled.

1999-11-02  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dynamic.c: Work on the dynamic translator restarted. The first
	correct dynamically code was generated today: a small step for
	humanity, a big step for me (hmmm... maybe it was the other way
	round...) -- runs up to the first `inlined opcode-non inlined opcode-
	inlined opcode' pattern (line 1358 of Builtins.st)
	* lib/interp.c: Work on the dynamic translator restarted

1999-10-31  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Fixed bug when compiling an integer constant
	that did not fit in the first 31 literals (`push instance
	variable[x]' was emitted instead of `push literal[x]')

1999-10-31  Paolo Bonzini  <bonzini@gnu.org>

	*** Third beta of 1.7 (labeled 1.6.82) released

1999-10-30  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: A few bytecodes were still sending #booleanRequired
	instead of #mustBeBoolean (see May 3rd change).

1999-10-22  Paolo Bonzini  <bonzini@gnu.org>

	* lib/save.c: Ensure that upon load the heap is at least 50% free.

1999-10-21  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Added characterArrayClass
	* lib/dict.h: Added characterArrayClass
	* lib/lib.c: Added CharArray.st

1999-10-20  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: The new startup sequence (Oct 9) allowed to
	make the dictInit function (now called initNilVec) static.
	So that has been done since dictInit was just a hack:
	it initialized variables in dict.c like initDictionary,
	but while the latter is called from lib.c, dictInit had to
	be called from initOOPTable and loadFromFile).
	* lib/dict.h: Removed declaration of dictInit.
	* lib/oop.c: Removed call to dictInit.

1999-10-12  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dld_hpux.c: `return 0' was missing in gst_dld_init
	* lib/lib.c: Put the image in the local directory if the
	image directory is missing or not writeable.
	* lib/sysdep.c: Added fileIsWriteable, plus usage of time_t;
	strdup was erroneously declared in getFullFileName.

1999-10-11  Paolo Bonzini  <bonzini@gnu.org>
	
	* lib/comp.c: Removed addForcedSelector (a copy of addForcedObject).
	Open coding of #whileTrue, #whileFalse, #repeat; removed open
	coding of #yourself.
	* lib/dict.c: Restored lookupKeyClass and its definition as I
	finally understood what it was meant to do; modified Association's
	definition (doesn't include key instance variable anymore).
	* lib/dict.h: Same as above

1999-10-10  Paolo Bonzini  <bonzini@gnu.org>

	* lib/oop.c: Added reallocOOPTable.
	* lib/oop.inl: Call reallocOOPTable instead of exiting when
	ran out of OOP table slots.
	* lib/save.c: FixupObject, restoreObject, restoreInstanceVars accept
	an gst_object instead of an OOP; more coherent with their names and
	a bit more efficient too.  Also moved updating of CFunctionDescriptors
	from restoreInstanceVars to fixupOOPInstanceVars (it is not needed
	when saving, only when loading, and was the only part of the code
	that required the parameters to be OOPs).
	* lib/save.h: FixupObject and restoreObject are now public.

1999-10-10  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.h: Define the `min' and `max' macros.
	* lib/lib.c: Used oopTableSize instead of OOP_TABLE_SIZE;
	use additional parameter to initOOPTable.
	* lib/oop.c: Added to initOOPTable a parameter to specify the
	table size; defined oopTableSize and used instead of
	OOP_TABLE_SIZE.
	* lib/oop.h: OOP_TABLE_SIZE became INITIAL_OOP_TABLE_SIZE;
	declared oopTableSize.
	* lib/oop.inl: Used oopTableSize instead of OOP_TABLE_SIZE
	* lib/prims.inl: Used oopTableSize instead of OOP_TABLE_SIZE
	* lib/save.c: Used oopTableSize instead of OOP_TABLE_SIZE;
	use additional parameter to initOOPTable.

1999-10-10  Paolo Bonzini  <bonzini@gnu.org>

	* lib/oop.c: Moved builtin objects at the front of the oop table;
	this is a first step towards a variable-sized oop table
	(believe it or not, I did it in less than half an hour!!).
	* lib/oop.h: Same as above.
	* lib/oop.inl: Same as above.
	* lib/prims.inl: Same as above.
	* lib/save.c: Same as above.
	* lib/sym.c: Same as above.

1999-10-09  Paolo Bonzini  <bonzini@gnu.org>

	*** Second beta of 1.7 (labeled 1.6.81) released

	* lib/bytecode.inl: Added a few experimental branch labels
	for the dynamic translator.
	* lib/prims.inl: Added primitive 90 to flush the dynamic
	translator's code cache.

	* lib/dict.c: Added code to reinitialize the global OOPs (which
	are not saved anymore so that the image is more compatible). Also,
	the OOP indices associated to Smalltalk, Processor and the
	SymbolTable are fixed so that we know them without storing them
	in the image file. Finally, declare the `Undeclared' dictionary in
	initSmalltalkDictionary().
	* lib/oop.c: Removed markGlobalOOPs (instead, just mark the
	`Smalltalk' dictionary).
	* lib/save.c: Removed the global OOPs; they are reinitialized
	every time in dict.c.
	* lib/save.h: Removed the global OOPs
	* lib/sym.c: Added undeclaredSymbol, and used in findClassVariable.
	* lib/sym.h: Added undeclaredSymbol.

1999-10-07  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Restored old MethodDictionary class (see
	March 29th, 1989 entry!) It was needed after all.
	* lib/dict.h: Same as above
	* lib/lib.c: Same as above
	* lib/save.c: Same as above
	* lib/sysdep.c: Fixed faked closePipe to return status of child
	process.

1999-10-02  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Was trimming the last character of the method's
	source code in FileSegments.
	* lib/lex.c: Was trimming the last character of the method's
	source code when creating Strings from source code read from
	a file.
	* lib/lib.c: Added -K option, don't crash on -I/-L/-K without
	mandatory argument.

1999-09-26  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: InitProcessSystem removed the initial process from
	its own process list -- result: as soon as `Processor yield' was
	called, highestPriorityProcess did not know that the active process
	was active!
	* lib/prims.inl: Relinquish control to other processes on #yield.
	* lib/lib.c: `gst -a' caused a segmentation violation
	* lib/sysdep.h: Declaration of `relinquish'.
	* lib/sysdep.c: Implemented `relinquish'.

1999-09-25  Paolo Bonzini  <bonzini@gnu.org>

	*** First beta of 1.7 (labeled 1.6.80) released

	* lib/bytecode.inl: Use areInts in open-coded operators.
	* lib/gst.h: Added areInts, removed F_FINALIZING.
	* lib/oop.c: Store objects to be finalized in a buffer, to avoid
	an OOP table scan.
	* lib/str.h: Added declaration of generic buffer functions
	* lib/str.c: Added generic buffer functions (not limited to chars)
	* lib/dld_aix.c: Added
	* lib/waitpid.c: Added
	* lib/strtoul.c: Added

1999-09-23  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dynamic.c: Created.
	* lib/dynamic.h: Created.
	* lib/obstack.c: Added, fixed to use _obstack_memcpy.
	* lib/obstack.h: Added.
	* lib/sysdep.h: Added flushCode.
	* lib/sysdep.c: Added flushCode & signalAfter implementation using
	fork()+getMilliTime().

	* lib/dict.c: Declare lookupTableClass
	* lib/dict.h: Declare lookupTableClass
	* lib/lib.c: Load LookupTbl.st and WeakObjects.st

	in lib.c

1999-09-15  Paolo Bonzini  <bonzini@gnu.org>

	* lib/cint.c: Added mkdir declaration.

1999-09-14  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Added DefaultSortBlock to SortedCollection.
	* lib/lex.c: Fixed bug; 8-bit characters *outside* string literals
	crashed the lexer.
	* lib/sysdep.c: Use getcwd if HAVE_GETCWD (new symbol) is set and
	getwd otherwise.  Old behavior was to use getcwd if HAVE_UNISTD_H
	was set and getwd if HAVE_GETWD was set

1999-09-13  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Compile doits in UndefinedObject.

1999-09-12  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Moved variables from ClassDescription; instanceVariables to
	Behavior; name/comment/category/environment to Class (they make no sense
	in Metaclass!).
	* lib/dict.h: Same as above.

1999-09-11  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Changes for namespaces (execute doits in the current namespace).
	* lib/dict.c: Same as above (shared pool variable search algorithm,
	new `environment' variable, declaration of currentNamespace).
	* lib/dict.h: Same as above (added `environment' variable to ClassDescription,
	declaration of currentNamespace).
	* lib/dict.inl: Same as above (setClassEnvironment).
	* lib/prims.c: Same as above (primitive 250 to tell the compiler about the
	current namespace).
	* lib/save.c: Same as above (added uppercaseSuperSymbol, currentNamespace).
	* lib/sym.c: Same as above (shared pool variable search algorithm).
	* lib/sym.h: Same as above (added uppercaseSuperSymbol).

1999-09-10  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: VariableWordSubclasses use accessors for 32-bit integers.
	BlockClosures are now variableWordSubclasses since the previous encoding
	was incompatible with the code to switch the endianness in a saved image.
	* lib/dict.inl: Added accessors for 32-bit integers (64-bit on Alphas).
	* lib/gst.h: Added warning that says Alphas are not ok yet.
	* lib/gst.y: Shell was unusable after a parse error -- solved.
	* lib/interp.h: New encoding of BlockClosures (see above).
	* lib/prims.inl: C object and memory address primitives use the above
	accessors.

1999-09-08  Paolo Bonzini  <bonzini@gnu.org>

	* lib/prims.inl: Flush the FileStream before reading its size.

1999-09-06  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Added idleTasks variable to ProcessorScheduler.
	* lib/interp.h: Added idleTasks variable to ProcessorScheduler.
	* lib/lib.c: Allowed -- to stop option parsing, to comply with getopt.
	* lib/sysdep.c: Added POSIX interrupt handling (sigprocmask); Win32
	code for alarms now uses kill(2) instead of manually calling the
	handler.

1999-09-02  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.y: Added support for [ :a :b || temp1 temp2 | ].
	* lib/lex.c: UnreadChar not static anymore.  Also removed scanStringoid
	and moved its code to stringLiteral.  Parsing a comment does not
	actually require to store the whole comment in memory, so it is a
	conceptually different operation.  Fixed for the change to str.c below.
	Removed memory leak in printToken (not so important since it's just
	debugging code, but it's a bug).
	* lib/lex.h: UnreadChar is now extern.
	* lib/lib.c: Removed references to resizeString.
	* lib/str.c: Removed resizeString, curStrBuf now returns a copy of the
	string (previously it was a chore left to its caller through strdup).

1999-08-31  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Registers where the interpreter's ip and sp stay are
	hard-coded for most architectures.  Added definitions for the high
	speed interpreter with dynamic translation.
	* lib/interp.inl: Moved internal accessors to interp.c; moved object
	equality and hashing functions to dict.inl (the only places where they
	were actually used).

1999-08-30  Paolo Bonzini  <bonzini@gnu.org>

	* lib/bytecode.inl: Created from part of interp.c
	* lib/gst.h: Removed `extern' definition of the instruction pointer.
	* lib/interp.c: Made the instruction pointer static; prepared for the
	new bytecode.inl file; relativeByteIndex is replaced by
	currentBytecodeIndex; added definitions of the latter macro.
	* lib/interp.inl: Removed relativeByteIndex.
	* lib/prims.inl: RelativeByteIndex is replaced by currentBytecodeIndex.

1999-08-29  Paolo Bonzini  <bonzini@gnu.org>

	*** Version 1.6.2 released.

1999-08-27  Paolo Bonzini  <bonzini@gnu.org>

	* lib/cint.c: Always define DLD functions (at worst they're stubs)
	* lib/dld_none.c: Created.
	* lib/lib.c: Always load DLD.st (at worst it refers to C stubs)

1999-08-26  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Put CDoubleMin and CDoubleMax in the Smalltalk dictionary.
	* lib/interp.c: NEXT_BYTECODE was not defined for old (switch statement)
	dispatching.

1999-08-08  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: In initRuntimeObjects, define the ImageFileName global
	as equal to binaryImageName.
	* lib/lib.c: Load .stpre only when creating local image files.  Removed
	findImageFile.  Option -v shows the hard-coded kernel and image paths.
	binaryImageName is not static anymore, defaultImageName is.
	* lib/lib.h: Removed findImageFile.  binaryImageName is now declared
	here as an extern symbol, and defaultImageName is not.
	* lib/prims.inl: `Smalltalk snapshot' primitive (250) removed -- the
	new ImageFileName global makes it redundant.
	* lib/save.c: LoadFromFile now expects a full path to the image just like
	saveToFile, does not call findImageFile.

1999-08-07  Paolo Bonzini  <bonzini@gnu.org>

	* lib/cint.c: Declare `unlink' (valid only for files) instead of `remove'
	(which nukes whole directories too) to be used to implement
	File class>>#primRemove:
	* lib/sysdep.c: Added simulation of popen and pclose in openPipe
	and closePipe.

1999-08-07  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.h: InitSTDIOObjects became initRuntimeObjects
	* lib/dict.c: InitSTDIOObjects became initRuntimeObjects, and various
	initializations (Features, KernelPath, ImagePath) were moved here from
	initSmalltalkDictionary.  This completes the change made on July 14th.
	* lib/lib.c: InitSTDIOObjects became initRuntimeObjects

1999-08-06  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.inl: RelativeByteIndex now explicitly casts to int for
	Alpha compatibility.
	* lib/sym.c: Switched from int to long when dealing with differences
	between addresses, for Alpha compatibility.
	* lib/dict.c: Switched from int to long when dealing with differences
	between addresses, for Alpha compatibility.

1999-07-15  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dld_gnu.c: Added gst_dld_exts (.o, .a)
	* lib/dld_gst.h: Added gst_dld_exts
	* lib/dld_gst.c: Added gst_dld_openext
	* lib/dld_hpux.c: Added gst_dld_exts (.sl)
	* lib/dld_ltdl.c: Added gst_dld_exts (dummy)
	* lib/dld_libdl.c: Added gst_dld_exts (.so, .a)
	* lib/dld_win32.c: Added gst_dld_exts (.dll, .exe)

1999-07-14  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.h: Added F_BYTE, used while saving to ease reloading
	if the endianness changes.
	* lib/save.c: Added ability to load images from machines with
	different endianness and to recognize (and reject) images from
	machines with different sizeof(long).  This change unveiled a bug
	in GNU C 2.7.2!!!
	* lib/dld_ltdl.c: Created (thanks to Alexander Shinn for pointing
	me to libtool!)

1999-07-10  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: InterruptHandler should set again the handler
	for SIGINT
	* lib/sysdep.c: Fixed syntax error. Also, sigaction should use
	SA_RESETHAND if available because signal is supposed to work
	that way.
	* lib/sysdep.c: #define SIGALRM if not provided by C headers.

1999-07-05  Paolo Bonzini  <bonzini@gnu.org>

	* gstconf.h.in: Changed USE_READLINE to HAVE_READLINE (more coherent)
	* gstconf.h: Same as above
	* lib/comp.c: Same as above
	* lib/lex.c: Same as above
	* lib/lex.h: Same as above
	* lib/lib.c: Same as above

1999-07-04  Paolo Bonzini  <bonzini@gnu.org>

	* lib/sysdep.c: Renamed dprintf to debugf. glibc 2.0 defines
	a different prototype for a function with the same name (glibc 2.1
	only defines it if __USE_GNU is defined and does not break gst).

1999-06-28  Paolo Bonzini  <bonzini@gnu.org>

	* lib/qsort.c: Added standard stuff to make alloca work.
	* lib/gstpub.h: Moved inclusion of gst.h *inside* `extern "C"'

1999-06-25  Paolo Bonzini  <bonzini@gnu.org>

	*** Bug-fixing version 1.6.1 released.

1999-06-21  Paolo Bonzini  <bonzini@gnu.org>

	* lib/alloc.c: In xrealloc, we must call malloc explicitly when
	the first argument is 0, since some reallocs don't do this.
	* lib/cint.c: Fix for Solaris' brokenness (in their stat.h, they use
	`#define st_atime st_atim.tv_sec')
	* lib/qsort.c: Added (from GCC).

1999-06-17  Mark Elbrecht  <snowball@bigfoot.com>

	*** Version 1.6 released.
	* lib/lex.c: Fix crash when using drive letters in isKernelFile.
	* lib/lib.c: For DOS, use '_stinit' and '_stpre' as init files since
	DOS doesn't allow a period to start a filename.

1999-06-09  Pahi Andras  <pahi@mozart.eet.bme.hu>

	* lib/cint.c: DefineCFunc makes a private copy with strdup of the
	C function's name. The problem is likely to root to the pre-DLD days
	(1989-1990) when only string constants were passed to defineCFunc, so
	strdup was unnecessary.

1999-06-03  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Added displayCompilationTrace
	* lib/comp.h: Added declaration of displayCompilationTrace
	* lib/prims.inl: If declaration tracing is on, shows new
	categories as encountered.

1999-05-30  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.h: Added default values for the definitions that used to
	be in gstpaths.h
	* lib/gstpaths.h: Removed since configure did not create it properly
	after the installer was fixed
	* lib/Makefile.in: Added definitions to be used in place of gstpaths.h
	* lib/lib.c: If the the paths cannot be located, try using the local
	directory
	* lib/lib.h: DefaultImageName is now a variable
	* lib/str.c: Added resizeString

1999-05-28  Paolo Bonzini  <bonzini@gnu.org>

	* lib/cint.c: Object passed as `unknown' or `self', whose class is not
	recognized, are now passed as an OOP (they used to be skipped).
	* lib/interp.c: the open-coded // was rounding like quo: Does.
	* lib/prims.inl: The base date for secondClock was 2 Jan 2000 instead
	of 1 Jan 2000.  This was apparent after the fix above.

1999-05-20  Paolo Bonzini  <bonzini@gnu.org>

	* lib/alloc.c: Moved platform-dependent definitions here.  Modified
	so that, if we replace libc's allocator, we define calloc too (see
	glibc's manual).  Also modified so that xmalloc exits if it fails.
	* lib/alloc.h: Removed platform-dependent definitions.  Now this
	file only contains extern declarations (correctly).

1999-05-15  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.h: Added code to #define `volatile' to nothing if it is
	not supported.
	* lib/interp.c: Modified to pass through -Wall when optimization
	is on.  This highlighted a possible (although never observed) bug in
	sendMessageInternal: the setjmp/longjmps in executePrimitiveOperation
	could have clobbered methodOOP, which is now declared volatile.

1999-05-14  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: Modified to (almost) pass through -Wall.
	* lib/cint.c: Modified to pass through -Wall.
	* lib/comp.c: Modified to pass through -Wall.
	* lib/dict.c: Modified to pass through -Wall.
	* lib/dict.inl: Modified to pass through -Wall.
	* lib/gstpub.h: Added C++ `extern "C"' guard.
	* lib/interp.c: Modified to pass through -Wall.
	* lib/interp.inl: Modified to pass through -Wall.
	* lib/lex.c: Modified to pass through -Wall.
	* lib/oop.c: Modified to pass through -Wall.
	* lib/save.c: Modified to pass through -Wall.
	* lib/sym.c: Modified to pass through -Wall.

1999-05-13  Paolo Bonzini  <bonzini@gnu.org>

	* lib/callin.c: Added objectAlloc.
	* lib/gst.h: Added guards to avoid including heavily implementation
	dependent stuff when gst.h is included by gstpub.h
	* lib/gstpub.h: Changed to use those guards.
	* lib/dld_hpux.c: Created.
	* lib/dld_libdl.c: New name of dld_sun.c
	* lib/lex.c: Stream description for readline streams is not
	`a Readline string' anymore, but `stdin' (since that's where we
	actually get the string).  Also, when readline is used I also
	include <readline/history.h> now; and I disable readline's auto-
	completion feature, not supported by gst (initializeReadline).


1999-05-11  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Various performance counters are now unsigned longs.
	* lib/comp.h: Various performance counters are now unsigned longs.
	* lib/interp.c: #mustBeBoolean is now sent to the object that should
	have been a Boolean, as the Blue Book says.  Plus, same as above.
	* lib/interp.h: Various performance counters are now unsigned longs.

1999-05-09  Paolo Bonzini  <bonzini@gnu.org>

	* lib/id.c: Removed -- I'm very sorry to do it, since it was created
	10 1/2 years ago, but it was a copy of str.c
	* lib/id.h: Removed -- I'm very sorry to do it, since it was created
	10 1/2 years ago, but it was a copy of str.h
	* lib/lex.c: Removed references to function that used to be in poor id.c;
	changed references to copyStr to use strdup.
	* lib/prims.inl: Added code to test for infinity, NaNs and other failures
	in mathematical functions (exp/ln/sqrt/trigonometry).
	* lib/str.c: Removed copyStr.
	* lib/sysdep.h: Added portable macros to test for nan and infinity.
	Not all libc's have isnan, isinfinity and the like.

1999-05-08  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: fixed bug when compiling to:do:/to:by:do: And the loop
	index temporary was in position 15 (a 2-byte push was erroneously
	compiled, since a 1-byte push can be used).
	* lib/interp.c: Did not trap divides by zero on open-coded // messages.
	* lib/lib.c: Added Transcript.st to the list of kernel files.
	* lib/oop.c: Character objects' objSize field was uninitialized. Fixed.
	* lib/prims.inl: fixed SIGSEGV on (IndexableClass new: ANegativeNumber).

1999-05-06  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Added exceptionHandlers variable to Process.
	* lib/gst.y: Fixed bug with conditional compilation -- conditional
	exclusion was not disabled by the double bang sequence.
	* lib/interp.h: Added exceptionHandlers variable to Process.

1999-05-03  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Changed the system message #booleanRequired to
	#mustBeBoolean for coherence with the Blue Book (I had not noted
	that passage).  Fixed async signals (actually, I just removed
	the error messages -- they seem to work as they are and their
	implementation is exactly the same as in the book...) and
	changed the signal handling routines to use them instead of
	separate variables.  Added asyncSignal().
	* lib/interp.h: Added declarations for asyncSignal().
	* lib/interp.inl: Fixed unparenthesized arguments in the `equal' macro.
	* lib/gstpub.h: Added declarations for asyncSignal().
	* lib/lib.c: Search for a local copy of the kernel files in the
	`kernel' subdirectory of the local directory; always save the
	kernel sources as FileSegments.  This way, GNU Smalltalk works
	both if a) it is installed and the kernel lies in /usr/local/share
	b) it is not installed and everything is done inside the
	user's home directory c) it is not installed, we are under Windows
	and everything is done inside the current directory (maybe I'll
	switch to the executable directory in the future...)

1999-04-29  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Now does compile correctly optimized selectors whose
	block arguments have arguments or temporaries.  In fact I simply
	don't optimize them -- but maybe I will sooner or later.  Also,
	#timesRepeat:, #to:do: and #to:by:do: are now open-coded.
	Finally, I fixed the fact that the bytecodes for an erroneous method
	were put at the beginning of the next syntactically valid method.
	* lib/lib.c: The `Smalltalk Ready' banner is now `GNU Smalltalk Ready'.
	* lib/save.c: Added timesRepeatColonSymbol, toColonDoColonSymbol and
	toColonByColonDoColonSymbol.
	* lib/sym.c: Same as above.
	* lib/sym.h: Same as above.

1999-04-27  Paolo Bonzini  <bonzini@gnu.org>

	*** Version 1.5.beta3 released.
	* lib/alloc.c: Added inclusion of stdlib.h (or malloc.h for old C's)
	when the custom allocator is not used.
	* lib/byte.c: Fixed optimization of pushIndexed.
	* lib/dld_sun.c: Added missing semicolon.
	* lib/interp.c: Finished new GCC implementation at last -- now we
	only have to do a single goto for EVERY bytecode.  Maybe something
	better could be done by caching dispatchVec in a register...  Auto-
	matic #undef-ining of USE_OLD_DISPATCH is now based on the new
	gstconf.h definition HAVE_GOTO_VOID_P (used to simply check __GNUC__).

1999-04-25  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: Added optimization of nopBytecode.  Added `replace
	stack top' bytecodes 140-142 in optimizeBasicBlock.
	* lib/byte.h: Added `replace stack top' bytecodes.
	* lib/comp.c: Added yourselfSymbol in whichBuiltinSelector (yourself
	is now open-coded).
	* lib/interp.c: Added `replace stack top' bytecodes.
	* lib/prims.inl: Changed GC-tuning primitives (spaceGrowRate
	and growThreshold) to accept integers too.
	* lib/sym.h: Added yourselfSymbol.
	* lib/sym.c: Added yourselfSymbol.
	* lib/save.c: Added yourselfSymbol.

1999-04-23  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.h: Cleaned up some definitions for ANSI features which
	can be checked by autoconf -- the old #ifdef method only makes things
	cumbersome.  Also renamed config.h to gstconf.h, so that it can be
	installed without filename clashes.
	* lib/interp.c: Changed verbose execution tracing to print the stack
	top *BEFORE* the bytecode -- the output is easier to follow.  Added
	jump lookahead (see definition of JUMP_LOOKAHEAD).
	* lib/oop.c: Began switching to something resembling a generational
	collector.  Changed GC-tuning variables (spaceGrowRate/growThreshold)
	to be integers -- because they are now checked in allocObj and doubles
	are more expensive in busy code, I think.

1999-04-22  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.h: Merged bytecodes 138-139 (push/store outer temp) into a
	single bytecode 138, which can also do a `pop and store outer temp'.
	* lib/byte.c: Same as above. The new bytecode behaves much like bytecode
	126, so the code for that bytecode in the optimizer can be used by the
	new bytecode too.  Added more cases in the peephole optimizer.
	* lib/comp.c: Same as above.
	* lib/interp.c: Same as above. Moved various optimization #define's at
	the top of the file.

1999-04-20  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: Optimizer in and working.  Fixed challenging cases in
	the flow analyzer which were apparent now because the peephole
	optimizer does some `interesting' changes to the bytecode -- previously
	the changes were not `interesting' enough for these bugs to show up.
	Performance +5-10%, but some interesting optimizations are not there
	yet (e.g. pop-store/push --> store, and push/push --> dup).

1999-04-19  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: Added to the flow analysis some support for optimizing
	#ifTrue: and #ifFalse: in the common case where their result is
	discarded.  Added a first peephole optimizer in optimizeBasicBlock.
	* lib/byte.h: Added nop bytecode 139
	* lib/comp.c: Changed the compilatation of #ifTrue:/#ifFalse: to one
	which is more optimizable if the result is discarded.  #and:/#or: are
	left as they were because their result is usually kept.  Also ALWAYS
	put a pop bytecode at the end of a statement -- it makes flow analysis
	simpler and is removed by the peephole optimizer if unnecessary.
	* lib/interp.c: Added nop bytecode 139

1999-04-18  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: The new optimization scheme proved to be easily
	extendable (which is what I wanted). I added jump optimization
	(10 lines of code) and unreachable code elimination (5 lines) -- no
	big speed improvements, but now I have moer experience with
	optimization and will approach peepholing.
	* lib/byte.c: Modified various internal functions to avoid continuous
	reallocation of bytecodes.  For instance, reallocByteCodes uses
	xrealloc() -- it was always malloc-ing everything from scratch --
	and allocByteCodes and reallocByteCodes have a parameter with the
	amount of memory to be allocated.
	* lib/cint.c: Call initDldLib if HAVE_DLD is defined.

1999-04-16  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dld_gst.c: Created from old cxtnsn/dld.c
	* lib/dld_gst.h: Created
	* lib/dld_gnu.c: Created
	* lib/dld_sun.c: Created
	* lib/dld_win32.c: Created
	* lib/byte.c: Changed the algorithm for optimizeByteCodes.  Instead of
	doing a single scan on the bytecodes and fixing up jumps the hard way,
	I'm now dividing the bytecodes into basic blocks, optimizing each of
	them one at a time in optimizeBasicBlock.
	* lib/dict.c: Moved hasBlock to ContextPart, yanked it out from
	BlockContext and MethodContext.
	* lib/interp.c: Moved hasBlock to the fourth position (inside
	MethodContexts and BlockContexts) so that we can put it in ContextPart.
	* lib/lib.c: Load DLD.st from kernel if HAVE_DLD is defined.

1999-04-12  Paolo Bonzini  <bonzini@gnu.org>

	* lib/sysdep.c: Functions handling time_t's now use signed longs.
	* lib/sysdep.c: Stole more portable implementations of adjustTimeZone
	and currentTimeZoneBias from GNU Emacs.  Added support for broken
	versions of localTime(3) that cache the time zone.
	* lib/sysdep.h: Functions handling time_t's now use signed longs.

1999-04-10  Paolo Bonzini  <bonzini@gnu.org>

	*** Version 1.5.beta2 released.
	* lib/cint.c: My_stat now adjusts file times to local times.
	* lib/sysdep.c: Added adjustTimeZone and currentTimeZoneBias.
	* lib/sysdep.h: Added adjustTimeZone and currentTimeZoneBias.

1999-04-09  Paolo Bonzini  <bonzini@gnu.org>

	* lib/cint.c: Fixed my_stat to return times relative to 1/1/2000
	to avoid possible overflows (which would have happened around 2004
	on 32-bit machine, and around 8.000.000.000 AD on 64-bit ones...).

1999-04-08  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Fixed bug in sendMessageInternal and sendBlockValue.
	Basically, we now make sure that sp and thisContext->spOffset are
	consistent whenever a GC could happen; otherwise, fixupObjectPointers
	recomputes thisContext->spOffset from sp, storing an erroneous value
	into the former.

1999-03-29  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.h: Added definition of WIN32 because Cygwin only defines
	_WIN32, but many programs rely on WIN32 instead.

1999-03-22  Paolo Bonzini  <bonzini@gnu.org>

	* lib/sysdep.c: Fixed Win32 version of Delays, which was buggy if a
	delay had to cancel the previous one.  The new version is also much
	more precise.

1999-03-21  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Changed Integer relational operators to not do a
	toInt() (instead we use a simple typecast).

1999-03-15  Paolo Bonzini  <bonzini@gnu.org>

	*** Version 1.5.beta1 released.
	* lib/dict.c: Changed to use setCObjectValueObj and cObjectValueObj.
	* lib/dict.h: Doc fixes for CObject.
	* lib/dict.inl: Added setCObjectValueObj and cObjectValueObj.  Now, the
	address pointed by the CObject is the LAST instance variable (including
	indexed ones), not always the SECOND (which could still be a fixed
	one).  For currently defined CObject subclasses this was not a problem,
	but it could have been a serious one if a CObject subclass declared
	additional instance variables.
	* lib/prims.inl: Changed to use setCObjectValueObj and cObjectValueObj.

1999-03-13  Paolo Bonzini  <bonzini@gnu.org>

	* lib/cint.c: Was crashing if a call-out to a non-existent function
	was attempted.
	* lib/comp.c: Fixed a strange bug I'm not sure I understood well. It
	seems that, if an error occurred in a method with literals, and if an
	immediately following method had literals, the literal array
	contained bogus data and GST would lose.  I don't think it was there
	before my March 3rd change...

1999-03-11  Paolo Bonzini  <bonzini@gnu.org>

	* lib/lib.c: Added --silent as a synonim of --quiet and -q.

1999-03-03  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Added stack depth tracing (variables and macros
	containing stackDepth).  Made makeNewMethod public, to avoid lots of
	duplicate code for the C and Smalltalk compiler.
	* lib/prims.inl: Added primitive 79, which maps to makeNewMethod.
	* lib/interp.c: Added support for mixed size contexts. Added
	resetFakeContexts.
	* lib/interp.c: The change above unveiled lots of bugs - especially
	uninitialized pointers here and there. In particular: a) GST would
	core dump when you did a send to super from a class without a
	superclass; b) prepareExecutionEnvironment set the stack pointer of
	the context to 0 instead of -1 so markAnOOPInternal would try to
	mark an additional stack slot.
	* lib/oop.c: In minorGCFlip, call resetFakeContexts at the end instead
	of using deallocFakeContext for every context.

1999-02-28  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Modified compileAssignments to use preferrably the
	`storeIndexed' bytecode. This is faster and also makes the task
	of an eventual bytecode optimizer a bit simpler.
	* lib/byte.c: Added truncateByteCodes.  Moved optimizeByteCodes
	here and made it extern (it was a static in lib/comp.c), and added
	it some (working but currently not used) code.
	* lib/byte.h: Added optimizeByteCodes and truncateByteCodes

1999-02-27  Paolo Bonzini  <bonzini@gnu.org>

	* lib/prims.inl: Added primitive 101 (ProcessorScheduler>>
	isTimeoutProgrammed).
	* lib/dict.c: Added DelayProcess and IdleProcess as
	Delay's class variables
	* lib/interp.c: In initProcessSystem, leave the processes the way
	they were unless we get here after a deadlock.

1999-02-26  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Changes to have an error-free compile with
	-pedantic.  Also fixed highestPriorityProcess to return the
	active process if it is not waiting on a semaphore (because
	`Processor yield' must not stop execution if the only
	runnable process is the active one).
	* lib/lex.c: Added support for -s command line option in
	isKernelFile.
	* lib/lib.c: Added -s command line option.
	* lib/oop.c: Removed arithmetics on void * in realizeOOPs.

1999-02-23  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.y: Added #'abcd' symbols (not in Smalltalk-80,
	but ANSI and common in many commercial Smalltalk
	implementations).

1999-02-22  Paolo Bonzini  <bonzini@gnu.org>

	* lib/lib.c: Moved some initializations *after* parsing the
	command line (obviously *before* loading user files),
	so that parameters on the cmdline can influence the
	initialization process.

1999-02-21  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Added printing of what is the erroneous method in
	sendMessageInternal.  Also renamed global SP/IP to outerSP and
	outerIP (which are then #defined to ip and sp in gst.h), so that
	there is no name collision between the local IP/SP and the global
	ones; and eliminating ipAddr/spAddr we get some more speed. But
	remember this when using GDB!!

1999-02-18  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Struggled to make the process system work as
	intended; it still has a few bugs but it mostly works (for
	example, philosophers now work).

1999-02-16  Paolo Bonzini  <bonzini@gnu.org>

	* lib/oop.c: Started switching to generational GC!! In short,
	minor GCs only take care of fake contexts and are faster 
	because no sweeping happens; major GCs don't bother of 
	fake contexts (they assume there are none) and deal with 
	removing real unused objects.

1999-02-15  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.h: Added bigLiteral bytecode.
	* lib/comp.c: Changed so that methods are normal objects - no
	more variable classes and variable byte classes at
	the same time. Now, the header does not include the
	number of literals, so I also added code to use the
	new 126 bytecode.
	* lib/interp.c: Changed so that methods are normal objects - no more
	variable classes and variable byte classes at the
	same time.
	* lib/interp.inl: Changed so that methods are normal objects - no more
	variable classes and variable byte classes at the
	same time.
	* lib/prims.inl: Now methods are normal objects - no more variable
	classes and variable byte classes at the same time.
	So I removed primitives 68/69/79.
	* lib/save.c: Changed so that methods are normal objects - no more
	variable classes and variable byte classes at the
	same time.

1999-02-14  Paolo Bonzini  <bonzini@gnu.org>

	* lib/oop.c: Experimentally moved markGlobalOOPs at the START
	of the marking phase, so that by the time the other
	objects in the root set are dealt with, many objects
	will have been marked. This might improve a bit GC
	locality of reference.
	* lib/save.c: Experimentally reorganized the global OOPs.
	smalltalkDictionary and the symbols at the END of
	the global OOP table, so that by the time they are
	marked other objects will have been dealt with and
	recursion will be more shallow; this might improve
	a bit GC locality of reference.

1999-02-13  Paolo Bonzini  <bonzini@gnu.org>

	* lib/sysdep.c: Using setSignalHandler() inside signalAfter().

1999-02-12  Paolo Bonzini  <bonzini@gnu.org>

	* lib/sysdep.c: GetCurDirName, now performs special error handling
	when getcwd is used (code stolen from the gettext
	library's source code, by David MacKenzie).

1999-02-09  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.h: Moved incubator here from oop.h so that it is public
	* lib/oop.h: Moved incubator to gst.h so that it is public (see
	comment in GST 1.1.5 - "it is likely that this
	interface will be moved..."

1999-02-08  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: Print new bytecode 126 for many literals, > 64.
	* lib/cint.c: Removed code to print "function not registered"
	message - Smalltalk code handles that now.
	* lib/lib.c: CFuncs.st is now loaded *after* CObject and CType -
	a logical choice since C function declarations could
	use CTypes.  Added PkgLoader.

1999-02-06  Paolo Bonzini  <bonzini@gnu.org>

	* lib/prims.inl: Sped up nextInstance by avoiding to search in the
	unused OOPs.

1999-02-05  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Added callbacks #booleanRequired and #interrupt.
	Implemented bytecode 126 for many literals, > 64.
	* lib/prims.inl: Primitive 255 now does not blindly set inCCode to
	false if a C callout made a callin which in turn made
	a callout.

1999-02-04  Paolo Bonzini  <bonzini@gnu.org>

	* lib/lex.c: Modified so that a bang is not part of a binary op.
	It's just a one-char token like [ and #.  Needs
	fixing, though.

1999-02-03  Paolo Bonzini  <bonzini@gnu.org>

	* lib/callin.c: Changed calls to yyparse() to parseStream().
	* lib/comp.c: Changed calls to yyparse() to parseStream().
	* lib/interp.c: Changed calls to yyparse() to parseStream().
	* lib/gst.y: More attempts at simplifying things around:
	now an expression invoking methodsFor: can be
	as complex as desired. In addition I changed
	temporaries and primitive to have a default value,
	so that almost-duplicated rules (e.g. `statements',
	`temporaries primitive statements', `temporaries
	statements', `temporaries primitive') can be put
	into a single one. Alas this causes 4 shift/reduce
	conflicts (2 in state 0, 2 in state 6) but Bison
	gracefully handles them and it makes the grammar more
	readable IMO.
	* lib/lex.c: Moved lex debugging here.  In addition, now
	you can compile this with NO_PARSE so that no parsing
	occurs - only lexical analysis.  To accomplish this, the
	callers need to call a function in lib/lex.c (parseStream)
	instead of yyparse().
	* lib/lib.c: Updated lex debugging and moved it to lex.c

1999-02-02  Paolo Bonzini  <bonzini@gnu.org>

	* lib/alloc.c: Added custom allocator, currently used only under
	Win32.  See comment in the file.
	* lib/alloc.h: Added custom allocator, currently used only under
	Win32.  See comment in the file.
	* lib/sym.c: internCountedString: The symbol OOP is now read only.

1999-02-01  Paolo Bonzini  <bonzini@gnu.org>

	* lib/oop.c: Fix in growMemory. Now it seems to work right -
	previously, it failed if thisContext was not a fake
	and the heap moved.

1999-01-29  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: Modified isSimpleReturn so that a "return literal[0]"
	method is optimized.
	* lib/comp.c: Modified isSimpleReturn (in byte.c) so that a "return
	literal[0]" method is optimized. The "primitive must
	be executed" case, which was previously identified by
	flags == 3, is now identified by primitiveIndex != 0.

1999-01-28  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Moved regressionTesting to lib.c; it seems more
	logical to me.
	* lib/gst.h: fix in incrInt/decrInt: It was not converting the
	OOP to a long before adding 2 - so it was actually
	adding sizeof(OOP)*2 = 16!
	* lib/lib.c: To make -S work when -i was specified too.
	* lib/oop.c: NilOOP, trueOOP and falseOOP are now initialized in
	allocOOPTable(), not initOOPTable(). Actually I can't
	guess why they weren't there in the first place.
	* lib/prims.inl: Added check for already closed file in fileOp: (if
	fileStream->file = nilOOP, fail). Added flushPrim
	and getBytePrim.
	* lib/save.c: Removed experimentally the code that saves and
	restores nil, true, false and the characters:
	why can't we initialize them just like if we were
	initializing the system from scratch, without
	an image?
	* lib/sysdep.c: OpenFile, removed references to BINARY_MODE_NEEDED
	(I had to remove it from the configure script because
	it did not work correctly, at least under Cygnus'
	Win32 port.

1999-01-27  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Smalltalk dictionary is now created with a larger
	size than it used to be (see the definition of INITIAL_SMALLTALK_SIZE).
	* lib/interp.c: Made the method cache an array of a struct instead of
	five different arrays.  A "return literal" method is
	optimized like "return self" and "return inst. var".

1999-01-26  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: Removed code for evaluating (parse last statement as
	return) - not needed since Smalltalk code implements
	evaluate: Also changed references to findVariable to
	prevent assignments into arguments.
	* lib/gst.y: Removed code to parse last statement as return -
	not needed since Smalltalk code implements evaluate:
	* lib/lex.c: Modified to have a variable indicating the name of
	the log file.
	* lib/lib.c: Changed -v to exit after the output, like
	--version. Added -l and -L to log to a file. Added
	long options.
	* lib/sym.c: Modified findVariable and localVarIndex so that
	assignments to arguments are detected.

1999-01-25  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.inl: Spiffed it up with a few register clauses.
	Also removed modulus operator (%) when possible.
	This increased performance (especially in message
	sends) only by 5%, but it was so easy I could not
	but do it!

1999-01-24  Paolo Bonzini  <bonzini@gnu.org>

	* lib/alloc.c: Added this banner.
	* lib/alloc.h: Created.
	* lib/lex.c: Fixed lineStamp() so that the format is consistent
	with GCC and other GNU programs: for example,
	"Integer.st:115: parse error")

1999-01-22  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.h: Moved SIG_ARG_TYPE from sysdep.c here.  Added paranoic
	checking of memset arguments when bzero is used.
	* lib/interp.c: Moved SIG_ARG_TYPE to gst.h
	* lib/sysdep.c: Moved SIG_ARG_TYPE to gst.h

1999-01-18  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.inl: Fixed bug in large integers.  I was not considering
	that the product of the low-order 15 bits could exceed 15 bits!

1999-01-16  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.h: Added byteStreamClass.
	* lib/interp.c: Yesterday I removed maxSize instance variable from
	WriteStream, so I had to remove it from the FileStream
	struct, either.
	* lib/lib.c: Added ByteStream.st.
	* lib/save.c: Added byteStreamClass.

1999-01-15  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Removed maxSize instance variable from WriteStream.
	Fixed missing isPipe parameter in addSTDIOObject.
	Added ByteStream.  Added CShortSize global.

1999-01-13  Paolo Bonzini  <bonzini@gnu.org>

	* lib/cint.c: Added getArgc and getArgv
	* lib/lib.c: Added ability to get argc/argv from Smalltalk code.
	* lib/sysdep.c: Fixed a small & invisible error, a 'start of comment'
	misplaced for a 'end of comment' (note by Paolo Bonzini  <bonzini@gnu.org>:
	congratulations for your sharp eye!!)

1999-01-11  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Yeah! Removed bitfields from InstanceSpec!!
	* lib/dict.h: Yeah! Removed bitfields from InstanceSpec!!
	* lib/dict.inl: Yeah! Removed bitfields from InstanceSpec!!
	* lib/gst.h: Yeah! Removed bitfields from InstanceSpec!!
	* lib/prims.inl: Yeah! Removed bitfields from InstanceSpec!!

1999-01-10  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Good!!  First change in 1999!!  Optimized out send to
	super.  I renamed sendMessage to sendMessageInternal
	and created two macros (sendMessage and sendToSuper)
	in interp.inl
	* lib/interp.h: Good!!  First change in 1999!!  Optimized out send to
	super.  I renamed sendMessage to sendMessageInternal
	and created two macros (sendMessage and sendToSuper)
	in interp.inl
	* lib/interp.inl: Good!!  First change in 1999!!  Optimized out send to
	super.  I renamed sendMessage to sendMessageInternal
	in interp.c and created two macros (sendMessage and
	sendToSuper) here.

1998-12-09  Paolo Bonzini  <bonzini@gnu.org>

	* lib/cint.c: Added my_stat for portability
	* lib/oop.c: Moved the code to nil out weak references *before*
	sweeping is done.  This is needed so that finalize
	methods which refer to weak objects already see nils.

1998-12-03  Paolo Bonzini  <bonzini@gnu.org>

	* lib/prims.inl: Added ability to create subclasses of CompiledMethod
	(for now, cannot add instance variables)

1998-11-28  Paolo Bonzini  <bonzini@gnu.org>

	* lib/comp.c: The method cache was not properly updated: test is
	1 to: 5 do: [ :i | Object compile: 'foo ^',
	i printString. (nil foo) printNl]
	Now I'm using invalidateMethodCache instead of updateMethodCache
	(see interp.c).
	* lib/interp.c: fix: Since updateMethodCache did not always work
	I replaced it with invalidateMethodCache, which is not as gentle but
	works (anyway compiles are not so frequent and it takes nothing to
	rebuild a good cache).  Also, thisContext's ip and sp (in sendMessage
	and sendBlockValue) are now updated *after* thisContextOOP is set to
	the newly created context.  The previous implementation caused mess if
	allocFakeContext() triggered a GC.

1998-11-27  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Added the Table class variable to Character.
	* lib/gst.h: Added finalization.
	* lib/oop.c: Added finalization.  Also added lastUsedOOP which
	is used to shorten the loops on the OOP table at GC
	time It was needed because the OOP table was scanned
	three times: once to mark dependents of finalizable
	objects, once to reverse pointers (prepareForSweep),
	once to scan for objects to be finalized.  Now the
	whole GC is on average 50% faster than it used to be
	BEFORE having to add all these cycles.
	* lib/oop.inl: Created
	* lib/prims.inl: Added finalization primitives 256-257
	* lib/sym.c: Added finalizeSymbol.
	* lib/sym.h: Added finalizeSymbol

1998-11-26  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.inl: Created

1998-11-25  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Moved many routines to dict.inl for speed.  Changed
	BlockClosure to a byte-subclass to save eight bytes.
	* lib/dict.h: Moved most things to gst.h, added dict.inl
	* lib/dict.inl: Created
	* lib/interp.c: Added primitive 104 (String hash function), inlined
	many things around.
	* lib/oop.c: Changed the way the marking system works.  Instead of
	two entry points (markAnOOP and markOOPRange) both
	relying on markAnOOPInternal and passing parameters
	to it through the copy stack, I have two macros
	(maybeMarkOOP and markOOPRange) which pass parameters
	to markAnOOPInternal through function arguments.
	markAnOOPInternal does its job calling itself
	recursively, doing everything on the stack without
	expensive mallocs.  This makes the code neater, since
	the whole marking system resides in a single function.
	* lib/prims.inl: Created from interp.c
	* lib/sym.c: Modified hashString to be more effective.

1998-11-24  Paolo Bonzini  <bonzini@gnu.org>

	* lib/lib.c: Added ContextPart.st, changed to try loading .stinit
	and .stpre from the current directory if the HOME
	environment variable is not found (fix for Win32).

1998-11-11  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Fixed bug in asObject primitive.  Was erroneously
	using oopAt(arg1-1) instead of oopAt(arg1).

1998-11-10  Paolo Bonzini  <bonzini@gnu.org>

	* lib/lex.c: Fixed so that _ *inside* an identifier is OK.

1998-11-08  Paolo Bonzini  <bonzini@gnu.org>

	* lib/byte.c: Added notNilSymbol and isNilSymbol.
	* lib/byte.h: Added notNilSymbol and isNilSymbol
	* lib/interp.c: Fixed bugs in returnWithValue (they had been there
	since 18 Oct...): contexts were returned to the free
	fake list even if they were not fake anymore (which
	happened if you did a snapshot).  Sooner or later, a
	normal object contended the same heap space with these
	contexts, wreaking havoc on the image. Also turned
	noParentContext to a macro and added notNil/isNil as
	bytecodes 206 and 207; these are optimized out to gain
	speed in some operations (e.g. Sets and Dictionaries).
	* lib/save.c: Added notNilSymbol and isNilSymbol
	* lib/sym.c: Added notNilSymbol and isNilSymbol.
	* lib/sym.h: Added notNilSymbol and isNilSymbol

1998-11-01  Paolo Bonzini  <bonzini@gnu.org>

	* lib/callin.c: Added vmsgSend.  Moved mstMalloc and mstGetCData here.

1998-10-26  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gstpub.h: Added vmsgSend.

1998-10-18  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Changed fake OOPs so that they have entries in the
	real OOP table.  This allows me to never realize
	the fake contexts unless a snapshot is being done.
	Less GC = more speed!!
	* lib/oop.c: Fake OOPs are now in the main OOP table.  Changed
	setOOPObject to a macro for SPEED!!
	* lib/oop.h: Added freeOOP(), realizeAllOOPs()

1998-10-16  Paolo Bonzini  <bonzini@gnu.org>

	* lib/cint.c: Added stringOut return type (frees string)

1998-10-15  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Added type 9 for CObjects and Memory (smalltalk OOP)

1998-10-12  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Added BlockClosure.  Changed BlockContext to reflect
	new architecture.  Changed Float to a variable
	byte class.
	* lib/interp.c: Added support for blocks as closures (partly I wrote
	it, part I stole it from Steve Byrne  <sbb@gnu.org>'s never made public
	1.1.6 version).  Started adding support for fake
	block contexts (see 1   Jan  91)

1998-10-10  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Added support for read-only objects (prims 233-234)

1998-09-26  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Fixed allocCObject.  Added IdentitySet.

1998-09-25  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Added a few register clauses.  Also changed
	implementation of "send ==" so it doesn't actually do
	the message sends, since == should not be overridden.
	* lib/lib.c: Added ValueAdapt.st, File.st, Directory.st,
	IdentitySet.st
	* lib/oop.c: Added a free list to OOP table.  This yielded, in
	general, good performance boosts, up to ten-fold for
	snippets that heavily allocate objects!! (on average,
	the number of bytecodes per second doubled)
	* lib/oop.h: Added refreshOOPFreeList(), to be used by save.c

1998-09-18  Paolo Bonzini  <bonzini@gnu.org>

	* lib/gst.h: Started adding support for read-only objects.
	* lib/interp.c: Removed last vestiges of previous garbage
	collectors. Removing loops that were not optimized
	out by compilers caused a 30% performance increase
	(not joking!).  Y2K change...  Time>>secondClock was
	about to overflow.  Also fixed sendBlockValue to
	check argument count.
	* lib/oop.c: Removed all vestiges of previous GC algorithms.
	This was a pity because it was really instructive
	but I was not able to read anything before ;-).
	* lib/oop.h: Fixed incubator bug (incAddOOP not in braces),
	removed maybeMoveOOP and localMaybeMoveOOP.

1998-09-10  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Added LargeIntegers and Fractions.  Tried to make
	nilFill faster.
	* lib/lib.c: Added LargeInteger.st, removed changes.st since its
	changes are incorporated in Fraction.st

1998-09-09  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Started adding support for LargeIntegers!!!

1998-09-07  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: Added Behavior>>#flushCache (primitive 89,
	as in the Blue Book).  Added bounds checking to	spaceGrowRate:
	(between 0 and 500)

1998-09-06  Paolo Bonzini  <bonzini@gnu.org>

	* lib/interp.c: FileStream>>nextPutAll: Primitive was giving access
	violations (!) if Integers were passed... definitely
	too greedy!  I've updated the Smalltalk code too, so
	that it handles the case, but anyway now the primitive
	fails.  On 3 Sep 98 I had broken Floats; fixed.

1998-09-03  Paolo Bonzini  <bonzini@gnu.org>

	* lib/dict.c: Added extensions to Date, modified Collection and
	SequenceableCollection so they are not indexable.
	Removed LookupKey.
	* lib/interp.c: Switched to openFile; corrected bug in floating point
	arithmetic primitives which never failed.  basicPrint
	doesn't output new-line.  Also corrected so that,
	when aborting execution, dead contexts are ignored
	and don't cause "Block returning to non-existent
	method context" errors.
	* lib/lib.c: Modified to use openFile, added a few loaded modules.

1998-09-02  Paolo Bonzini  <bonzini@gnu.org>

	*** Began development of version 1.6
	* lib/save.c: Switched to using openFile to open files
	* lib/sysdep.c: Added openFile, support for Cygnus Win32 added. A
	note on this is important.  Reluctantly I used Win32
	functions here and there.  I was not happy about that,
	but since it's the only way to do some things in
	an environment that does not fully comply to POSIX,
	I had to.

1995-12-16  Steve Byrne  <sbb@gnu.org>

	* lib/comp.c: Changed name to blockCopyColonTemporariesColonSymbol.
	* lib/sym.c: Changed name to blockCopyColonTemporariesColonSymbol.
	* lib/sym.h: Changed name to blockCopyColonTemporariesColonSymbol.

1995-11-04  Steve Byrne  <sbb@gnu.org>

	* lib/oop.c: Fixed allocObj to have what I think is the *right*
	algorithm -- simple, grows when needed.

1995-11-02  Steve Byrne  <sbb@gnu.org>

	* lib/oop.c: Fixed allocObj to properly grow when not enough
	space is required, and to terminate if the allocation
	cannot succeed.

	* lib/byte.h: Added pushOuterTempVariable and storeOuterTempVariable
	byte codes.

	unnecessary casting and unrolled expressions (*=
	becomes = *) to shut the Visual C++ compiler's
	warnings off.

1995-08-26  Steve Byrne  <sbb@gnu.org>

	* lib/comp.c: Merged Brad Diller's changes for dealing with parsing

	conditional on HAVE_SIGHOLD.

1995-08-20  Steve Byrne  <sbb@gnu.org>

	* lib/oop.c: Added growMemoryTo(); it's a variant of growTo which
	does not involve the garbage collector.
	* lib/oop.c: Fixed alignSize to not double align (we don't
	preserve that property during GC anymore anyway,
	and the floating point accessing functions in dict.c
	which were the initial reason for having it are now
	sensitive to whether aligned access to doubles is
	required by the hardware or not.
	* lib/oop.h: Added growMemoryTo().
	* lib/save.c: Switched to using growMemoryTo in loadFromFile so
	that if the saved image space is larger than the
	normal memory space, the space is grown to fit.

1995-07-26  Steve Byrne  <sbb@gnu.org>

	* lib/cint.c: Fixed the makeDescriptor function to issue an error if
	it cannot find a named C function.  Already located

	like them (incredible!).
	* lib/dict.c: Added CIntSize so that C struct can understand
	int size.
	* lib/gst.h: Removed mstconfig.h!!! Code is now not conditional
	on the presence of config.h.

	preprocessed-out code (OS/2's preprocessor doesn't
	understand backslash quoting.

	large number of immediately thrown away arrays.

1995-06-26  Steve Byrne  <sbb@gnu.org>

1995-01-05  Steve Byrne  <sbb@gnu.org>

	* lib/mstinterp.c: Fixed a bug when copying a fake method context
	(ip wasn't being updated, and so was pointing to
	dead storage).

	* lib/mstdict.c: Fixed CType to use the new type model.
	* lib/mstdict.h: Switched to the new CType model.

	longer function.

1994-12-03  Steve Byrne  <sbb@gnu.org>

	* lib/mstinterp.c: Added code stubs for asCData: Primitives.

1994-11-16  Steve Byrne  <sbb@gnu.org>

	* lib/mstinterp.c: Finally tracked down some problems with prims 183-185
	-- they were using the wrong variable to access the
	contents of the cobject, and it was just luck that
	it worked on Linux.

1994-10-08  Steve Byrne  <sbb@gnu.org>

	* lib/mstcomp.c: Fixed some bugs related to getting a GC during
	compilation (literals during compilation are part of
	the root set, etc.).
	* lib/mstinterp.c: Added SystemDictionary>>growTo: And moved a few
	builtins around.
	* lib/mstsym.c: Fixed the internCountedString bug by deferring OOP
	allocation until all instances have ben allocated.

1994-10-02  Steve Byrne  <sbb@gnu.org>

	* lib/mstoop.c: Made sure to turn off the free bit in moveOOP (no
	sense in moving an object that's freed, and moveOOP
	will not be called on a truly freed object; this
	change "repairs the damage" in cases where there is
	an accidental freeing occurring.
	* lib/mstsym.c: Fixed a bug in internCountedString that occurs other
	places where there is the possibility of doing a
	garbage collection just after a newly allocated object
	which has not been added to a root-set-reachable
	object.  The GC sees that there are no references
	to the new object, and marks its oop free and does
	not copy the just allocated object into the new
	current semispace.  This problem can occur anywhere
	these conditions occur.  Given that allocOOP moves the
	object to the cur
