Paul Eggert 1ce8849f 2025-07-28T17:50:30 float-h: change IBM long double to match GCC 15 This is in response to the GCC developers; see <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=120993>. * lib/float.c (gl_LDBL_MAX): Remove the implementation for PowerPC, as it should no longer be needed. * lib/float.in.h (LDBL_MIN_EXP, LDBL_MIN_10_EXP, LDBL_MIN) (LDBL_MAX, LDBL_EPSILON, LDBL_NORM_MAX): On PowerPC with IBM long double, simplify by using the GCC 15 values unconditionally. These are the correct values according to the GCC developers and there seems little point to disagreeing with current GCC about obsolescent arithmetic that is so problematic in practice. * tests/test-float-h.c (test_long_double): Relax tests of LDBL_MAX when !LDBL_IS_IEC_60559, as the tests would now fail on PowerPC and they were not portable in that case anyway.

Bruno Haible 31e573de 2025-07-17T16:43:42 parse-datetime: Update documentation regarding non-Gregorian calendars. * doc/parse-datetime.texi (General date syntax): Mention that date syntax should use the Gregorian calendar. Change examples that use %Y to use LC_ALL=C, so that they work even for users in Thailand, Iran, or Ethiopia.
Collin Funk 17357997 2025-07-16T16:57:06 doc: Use @code around errno constants. * doc/posix-functions/mkfifoat.texi: Use @code for errno constants instead of @samp. * doc/posix-functions/mknodat.texi: Likewise. * doc/posix-functions/setenv.texi: Likewise. * doc/posix-functions/symlinkat.texi: Likewise. * doc/posix-functions/unsetenv.texi: Likewise. * doc/glibc-functions/sethostname.texi: Use @code around errno constants. * doc/posix-functions/chmod.texi: Likewise. * doc/posix-functions/posix_fallocate.texi: Likewise. * doc/posix-functions/ptsname_r.texi: Likewise.

Paul Eggert e94aad0c 2025-07-13T00:43:36 safe-alloc: make obsolete and remove REALLOC_N Problem reported by Vivien Kraus in: https://lists.gnu.org/r/bug-gnulib/2025-07/msg00073.html This module never caught on. * lib/safe-alloc.h (REALLOC_N): Remove. * modules/safe-alloc: Now obsolete. * tests/test-safe-alloc.c (main): Remove REALLOC_N test.
Bernhard Voelker f3aaeaf5 2025-07-09T21:06:12 regexprops-generic: update from regex.h * doc/regexprops-generic.texi: Re-generate by running the 'regexprops' binary from GNU findutils: ./regexprops "Regular Expressions" generic At least the recent(ish) change (efd5c380ff) to regex.h aligning gnulib with Emacs behavior had made this document out-of-date. Reported by Collin Funk in <https://lists.gnu.org/archive/html/bug-gnulib/2025-07/msg00037.html>. Additionally, today's findutils commit c9c2c51175 fixed the sort order of the Texinfo nodes.
Paul Eggert 6164b4cb 2025-07-08T17:34:25 float-h: work around GCC bug 120993 Also, fix a too-low LDBL_MAX on this platform, a problem that contributed to LDBL_NORM_MAX test failures with C23 PowerPC GCC with ibmlongdouble. * lib/float.c (gl_LDBL_MAX): On PowerPC with ibmlongdouble, the correct value is 2**1024 - 2**918, not 2**1024 - 2**971. Also, use C99 hex double notation for the divisor, as it’s clearer and should work nowadays. * lib/float.in.h: Simplify by not worring whether it’s AIX or GNU/Linux when redefining LDBL_* macros on PowerPC GCC with ibmlongdouble, as the problem seems to be universal then. (LDBL_NORM_MAX): On PowerPC GCC with ibmlongdouble, define to be LDBL_MAX, so that it’s 2**1024 - 2**918, doubling GCC’s value if supplied. * modules/float-h-tests (Depends-on): Remove floorl, ldexpl. Add truncl. (test_float_h_LDADD): Likewise for libraries. * tests/test-float-h.c (test_isfinitel): New static function, so that we need not rely on isfinitel. (normalize_long_double): Work even if X is negative or not finite. Do not rely on frexpl or ldexpl. Use truncl instead of floorl so that the negative results are consistent with positive. Defend against fritzy PowerPC long double arithmetic.

Paul Eggert bc1bf2fc 2025-05-26T18:30:18 fcntl-h: support O_DIRECTORY It is relatively easy to support O_DIRECTORY on platforms that lack it, so let’s do that instead of having to work around bugs like <https://bugs.gnu.org/78509#95>. * lib/fcntl.in.h (O_DIRECTORY): Default to 0x20000000 not 0, since Gnulib now supports it. * lib/open.c, lib/openat.c (OPEN_TRAILING_SLASH_BUG): Default to false, so that this can be used outside #if. (open, openat): Add support for O_DIRECTORY on platforms that lack it. If fstat fails, fail instead of assuming the file is a directory, since failure can occur due to EOVERFLOW, etc. Rearrange code to minimize differences between open.c and openat.c. * m4/fcntl-o.m4 (gl_FCNTL_O_FLAGS): Also test O_DIRECTORY, and define HAVE_WORKING_O_DIRECTORY if needed. Prefer AS_CASE for Emacs’s benefit. * m4/open.m4 (gl_FUNC_OPEN): * m4/openat.m4 (gl_FUNC_OPENAT): Require gl_FCNTL_O_FLAGS and replace the function if O_DIRECTORY does not work. * tests/test-open.h: Test O_DIRECTORY.
