Wed Feb  8 09:44:38 1995  Takashi Chikayama  (chik@gydra)
* Fixed the problem of useless reference to the table defined_modules.
This was due to unused external references to method tables of predicate
and module objects, which made the linker to think that objects for these
classes are required.  To solve this problem, extern declarations of these
tables are deleted from gmodule.h and extern declarations of predicate
method tables are inserted wherever a module or predicate object constants
are needed.  The same problems with other classes that the KLIC kernel
knows of (gmodule.h, g_float.h, g_string.h, g_vector.h, generate.kl1,
write.kl1).

elements (write.kl1).
* Inserted inclusion of stddef.h (xio.c).

Configure, Makefiles).

functions and for future revision for unifying I/O for distributed version
(basic.h, xio.c <new addtion>, many files invoking those functions,
runtime/Makefile).
* Fixed buggy rule for verifying the compiler (used to use the original
compiler for the verification) (runtime/Makefile, compiler/Makefile).

such as FILE-t.c.

making different versions of runtime library (Configure, Makefile.tail,
runtime/Makefile).
* Separated specification of Unix-level signal handling and slit-check
level signal handling (signal.c).

* Changed code generation strategy for structure elements and goal
arguments when the element/argument is a structure element.  The element

* Alpha release of 1.510 within ICOT.
* Fixed non-returning function declaration problems (many files).
Actually, the problem is not solved completely, as we haven't found good
way to tell older versions of gcc of the fact in a K&R compatible manner.
* Fixed wrong order of storage class (static) and Const keywords (many
individual files directly, write.c for compiler code generation and
klicdb.c for database file generation).
* Fixed signed/unsigned problem in argument range checks (gmvv.c,
gstring.c).
* Merged patches for distributed processing (many files in runtime).
* Merged the functionalities of trace_printf in trace.c to debug_printf in
debug.c; also sped up debug_printf a bit (trace.c, debug.c).

Tue Nov  8 11:04:12 1994  Takashi Chikayama  (chik@ss108)

things (macro.kl1).

characters of printf (debug.c).

(runtime/Makefile).

maintaned correctly when a deadlock is detected (gc.c).
* Cleaned up trace printing for distributed parallel system (trace.c,
traceio.h).

Mon Oct 31 17:19:41 1994  Takashi Chikayama  (chik@ss108)
* Changed deref_and_jump macro (index.h) so that compiled codes only
dereference one level.  Changed faisus.c to take care of multiple level
indirections.  This makes code shorter without much runtime overhead.
Several occurences of deref_and_jump in files directly written in C are
changed to avoid its use.
* Fixed "pvm3.h" to <pvm3.h> in several files.
* Added suspended goal dump routine to runtime/trace.c.
* Fixed Configure to respect environment variable values as default values
of PVM_ROOT, PVM_ARCH and PVMLIB.
* Fixed asynchronous I/O handling (gunix.kl1) so that:
  - sync/1 message won't deadlock, and
  - write_buf tries again when not whole of the buffer is written.
* Changed the description of I/O streams in the manual to explicitly state
that I/O messages should not be sent to unix or klicio streams.

Mon Nov 07 10:25:00 1994  Kouichi Kumon (kumon@icot.or.jp)
* Unify level0/1 encoding routines into encode_data(). Those are
  distingushed by eager_transfer_level (val_hndl.c).
