scm-5f4 news:
scm-5f4 releases Radey Shouman's vicinity extension and fixes
compiler-dependent arithmetic problems. Details at
<http://cvs.savannah.gnu.org/viewvc/*checkout*/scm/scm/ChangeLog>
2023-10-16 Aubrey Jaffer <agj@alum.mit.edu>
* subr.c (scm_big_and): Patch from Radey to fix
(logior 0 (ash -1 64)) => 0 on 64 bit hardware.
2023-10-14 Aubrey Jaffer <agj@alum.mit.edu>
* mkimpcat.scm: Aubrey Jaffer <agj@alum.mit.edu>
Patch from Radey Shouman to use SLIB's new catalog:expand-path.
2023-08-15 shouman <shouman@jaffer-Vivobook-ASUSLaptop-X1703ZA-K1703ZA>
* debug.c:
Summary: Fix recent breakage in printing #@lambda expressions.
* debug.c, eval.c, repl.c, scm.h, sys.c:
Use IFLAGs for environment markers instead of
integers, to simplify debugging. Bash egc roots that are collected during main heap gc,
so we don't keep pointers to free cells.
2023-08-04 Radey <shouman@comcast.net>
* build.scm (gnu-win32 platform): For compile-dll-c-files and make-archive change "dllwrap"
call to "gcc -shared", dllwrap is deprecated. For link-c-program add linker directives to produce
.def and .lib files. scm.lib is required for linking dlls.
* scmfig.h: #define HAVE_DYNL if SCM_WIN_DLL is #defined, so init_dynl is called.
2023-08-04 Radey Shouman <shouman@comcast.net>
* scl.c (scm_intexpt): Fix overflow detection so that it works
without -fwrapv and with optimization. Uses a similar strategy to
that used for fixnum product.
2023-08-04 Radey Shouman <shouman@comcast.net>
* r4rstest.scm (test-bignum): Added some tests of EXPT requiring bignums.
2023-07-28 Radey Shouman <shouman@comcast.net>
* r4rstest.scm (test-bignum): Add test for bignum ash of -1.
2023-07-28 Radey Shouman <shouman@comcast.net>
* subr.c (scm_big_ash): Fix bug when first argument is 0 or -1 and
shift is a multiple of bigdig bits. Gave unpredictable results
due to internal array bounds error.
2023-07-24 Radey Shouman <rshouman@pmdlinux>
* scm.h (SCM_DLL_EXPORT, SCM_EXPORT): Changed for win32 so
that build with dynamic loading works.
* repl.c (input_waiting): For win32 fix so that this works
for an input pipe.
* scm.c (init_buf0): For win32 make stdin unbuffered if
an input pipe because it is when running in an emacs buffer.
2023-07-21 Radey Shouman <shouman@comcast.net>
* r4rstest.scm: Add a few more bignum arithmetic tests. Beautify
output of some float r/w tests by not printing closure.
* scl.c (product): Fix fixnum*fixnum case. The result of an
overflowing signed product in C is implementation dependent, and
gcc uses this freedom to optimize out a check. Fixed by either
using unsigned product or by using new SCM_LLONG optional type
macro.
* sys.c (scm_maksubr, scm_make_cont): Improve clarity.
* scmfig.h: Add conditional #defines for SCM_LLONG, a signed type
wide enough to hold the product of scm_int*scm_int. Defined for
x86_64 and x86_32. Defining this will enable better performance
for product subr.
* scm.h: Added typedefs scm_int and scm_uint, currently these
are always long and unsigned long, but that would change for
a 64-bit windows port.
2023-07-16 Radey Shouman <shouman@comcast.net>
* rgx.c (lregcomp): Replace calls to scm_protect_temp with
volatile SCM array on stack.
* unif.c (make_sh_array): Replace calls to scm_protect_temp with
volatile SCM array on stack.
* ramap.c (ramapc, ramap, rafe, scm_array_index_for_each, array_imap):
Replace calls to scm_protect_temp with volatile SCM array on stack.
* posix.c (getgroups): Replace calls to scm_protect_temp with
volatile SCM array on stack.
* eval.c (map, for_each): Replace calls to scm_protect_temp with
volatile SCM array on stack.
* subr.c (divbigbig): Use volatile SCM array on stack for gc
protection. Float test now passes with -O3.
* scl.c (big2str, istr2flo, pmantexp2dbl): Add gc protection for
temporary SCM cells using volatile SCM array on stack. Remove
calls to scm_protect_temp*.
2023-07-15 Radey Shouman <shouman@comcast.net>
* sys.c (scm_egc): Use s_numheaps instead of literal string.
2023-07-13 Aubrey Jaffer <agj@alum.mit.edu>
* keysymdef.scm, x11.scm: Updated.
* Makefile (*.opt): Removed Makefile dependency so that
user's customization persists.
2023-07-12 Radey Shouman <shouman@comcast.net>
* ramap.c (scm_array_index_for_each): use scm_protect_temp2 instead
of scm_protect_temp twice.
* scl.c (istr2flo): GC protect locals manstr and second.
* subr.c (divbigbig): GC protect locals quocell and dencell.
* sys.c, scm.h: Add scm_protect_temp2, to simplify GC protection
of two local variables. Procedure does literally nothing, but calling
it should make it harder to optimize SCM locals away.
2023-07-09 Radey Shouman <shouman@comcast.net>
* Make all .opt files depend on Makefile, so they do not need
to be deleted after editing Makefile.
2023-06-30 Aubrey Jaffer <agj@alum.mit.edu>
* Makefile ($(distdir)scm-$(VERSION)-$(RELEASE).exe): Added HTML
documentation dependencies.
* scm.nsi: Commented out test for SLIB.
2023-06-30 Aubrey Jaffer <agj@alum.mit.edu>
* Makefile ($(distdir)scm-$(VERSION)-$(RELEASE).exe): Added HTML
documentation dependencies.
* scm.nsi: Commented out test for SLIB.
2023-06-26 Aubrey Jaffer <agj@alum.mit.edu>
* r4rstest.scm (test-bignum): Added multiplication test for GCC
-O1 optimizer bug.
2021-09-01 Aubrey Jaffer <agj@alum.mit.edu>
* scl.c (istr2flo): Corrected case #ifndef SINGLES.
* unif.c (cvref): Corrected case #ifndef SINGLES.
2022-04-28 Radey <shouman@comcast.net>
* repl.c (scm_iprin1): When writing a string, reproduce all
escaped characters accepted as input: \0, \f, \n, \r, \t, \a,
\v, \" & \\. For _WIN32, #define strcasecmp as stricmp.
2022-04-27 Radey <shouman@comcast.net>
* socket.c (l_servinfo): Fix case of first argument an integer.
Add some casts to avert warnings.
