| | | | | | | | | | | | | Problem reported by Joe Nelson in: https://lists.gnu.org/r/bug-gnulib/2021-01/msg00152.html * doc/noreturn.texi: Improve. * lib/_Noreturn.h (_Noreturn): * m4/gnulib-common.m4 (gl_COMMON_BODY): Do not assume _Noreturn works as-is when __STRICT_ANSI__ is defined, unless __STDC_VERSION__ indicates C11 or later. * lib/_Noreturn.h (_Noreturn): Fall back on __attribute__ ((__noreturn__)) if Clang; this merges the 2020-08-10T23:53:13Zbruno@clisp.org patch to m4/gnulib-common.m4.

| | | | | | | | | | * m4/fchmodat.m4 (gl_FUNC_FCHMODAT): In the test whether fchmodat works, also test for the trailing slashes behaviour. Define HAVE_NEARLY_WORKING_FCHMODAT if this is the only missing feature. * lib/fchmodat.c (fchmodat): If HAVE_NEARLY_WORKING_FCHMODAT, handle trailing slashes here. * modules/fchmodat (Depends-on): Sort by condition, not alphabetically. * doc/posix-functions/fchmodat.texi: Document the AIX bug.

* tempname: don’t block for minutesPaul Eggert2021-01-082-2/+8
| | | | | | Derived from a patch proposed by Adhemerval Zanella in: https://sourceware.org/pipermail/libc-alpha/2021-January/121302.html * lib/tempname.c (random_bits): Use GRND_NONBLOCK.
* tempname: sync with proposed glibc patchPaul Eggert2021-01-082-3/+10
| | | | | | | This is from Adhemerval Zanella in: https://sourceware.org/pipermail/libc-alpha/2021-January/121301.html * lib/tempname.c (__lxstat64): Remove. (__lstat64, __stat64): New replacement macros. All uses changed.
* regex: stop using allocaPaul Eggert2021-01-083-20/+6
| | | | | | | * lib/regex_internal.h: Do not include <alloca.h> or define __libc_use_alloca or alloca. Patch written by Adhemerval Zanella: https://sourceware.org/pipermail/libc-alpha/2021-January/121374.html * modules/regex (Depends-on): Remove alloca-opt.
* regexec: remove alloca usage in build_trtablePaul Eggert2021-01-083-63/+28
| | | | | | | | | | | | | | | | Prompted by this different change proposed by Adhemerval Zanella: https://sourceware.org/pipermail/libc-alpha/2021-January/121373.html * lib/regexec.c (build_trtable): Prevent inlining, so that it doesn’t bloat the caller’s stack. Use auto variables instead of alloca/malloc. After these changes, build_trtable’s total stack allocation is only 20 KiB on a 64-bit machine, and this is less than glibc’s 64 KiB cutoff so there’s little point to using alloca to shrink it. Although Gnulib traditionally has used a 4 KiB cutoff, going to 20 KiB here should not be a significant problem in practice; Gnulib-using packages concerned about overflow of tiny stacks can compile with something like gcc -fstack-clash-protection. * config/srclist.txt: Comment out regexec.c for now.
* scratch_buffer: add scratch_buffer_dupfree macroPaul Eggert2021-01-082-0/+5
| | | | | * lib/scratch_buffer.h (__libc_scratch_buffer_dupfree): New macro, needed to support recent changes in this module.
* regex: remove alloca usage on regex set_regsPaul Eggert2021-01-084-22/+30
| | | | | | | | | | | Derived from this patch by Adhemerval Zanella: https://sourceware.org/pipermail/libc-alpha/2021-January/121372.html * lib/regex_internal.h: Include dynarray.h, for Gnulib. * lib/regexec.c (DYNARRAY_STRUCT, DYNARRAY_ELEMENT) (DYNARRAY_PREFIX): New macros. Include malloc/dynarray-skeleton.c. (set_regs): Use dynarray rather than alloca. * modules/regex (Depends-on): Add dynarray.
* dynarray: new modulePaul Eggert2021-01-0813-6/+1087
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * config/srclist.txt: Mention the new files. * lib/cdefs.h (__attribute_maybe_unused__): New macro, like Gnulib’s _GL_ATTRIBUTE_MAYBE_UNUSED but with glibc naming conventions. * lib/libc-config.h: Use it instead of __glibc_likely. * lib/dynarray.h, modules/dynarray: New files. * lib/malloc/dynarray-skeleton.c, lib/malloc/dynarray.h: * lib/malloc/dynarray_at_failure.c: * lib/malloc/dynarray_emplace_enlarge.c: * lib/malloc/dynarray_finalize.c, lib/malloc/dynarray_resize.c: * lib/malloc/dynarray_resize_clear.c, modules/dynarray: New files, from glibc with the following changes needed for portability to compilers that are not recent-enough GCC. * lib/malloc/dynarray_at_failure.c: Include stdlib.h, for abort. (__libc_dynarray_at_failure) [!_LIBC]: Simply abort. * lib/malloc/dynarray_emplace_enlarge.c: * lib/malloc/dynarray_resize.c: Include intprops.h, and use INT_MULTIPLY_WRAPV instead of __builtin_mul_overflow. * lib/malloc/dynarray.h (__libc_dynarray_at_failure): Use _Noreturn instead of __attribute__ ((noreturn)). * lib/malloc/dynarray_resize_clear.c: Do not include stdlib.h; it’s not needed. (__libc_dynarray_resize_clear): Do not do arithmetic on void *. * lib/malloc/dynarray-skeleton.c (struct DYNARRAY_STRUCT): Do not use anonymous unions, as they are not in C99. All uses changed. Use __nonnull (X) instead of __attribute__ ((nonnull X)), and __attribute_maybe_unused__ instead of __attribute__ ((unused)).
* bootstrap: Fix parsing of package name.Simon Josefsson2021-01-082-4/+13
| | | | | * build-aux/bootstrap (package): Attempt to use autoconf --trace to parse AC_INIT before falling back to sed expression.

* libc-config: simplify clang __has_* macrosPaul Eggert2021-01-063-44/+46
| | | | | | | | | | | | | | cdefs.h sometimes used names like __glibc_clang_has_attribute and sometimes __glibc_has_attribute.

All uses changed. (__glibc_clang_has_attribute): Remove. All uses replaced by __glibc_has_attribute. * lib/libc-config.h [!__glibc_likely]: Undef them here too.
