b9c361e4 - libc: Rewrite quick_exit() and at_quick_exit() using C11 atomics.

Tue, 26 Sep 2023 20:06:27 +0000

libc: Rewrite quick_exit() and at_quick_exit() using C11 atomics.Compiler memory barriers do not prevent the CPU from executing the codeout of order. Switch to C11 atomics. This also lets us get rid of themutex; instead, loop until the compare_exchange succeeds.While here, change the return value of at_quick_exit() on failure tothe more traditional -1, matching atexit().Sponsored by: Klara, Inc.Reviewed by: Olivier Certner, kevans, kibDifferential Revision: https://reviews.freebsd.org/D41936(cherry picked from commit 1dc3abb052430279e47c8922d22b30922adcf0f6)libc: Add a rudimentary test for quick_exit(3).Sponsored by: Klara, Inc.Reviewed by: kibDifferential Revision: https://reviews.freebsd.org/D41937(cherry picked from commit c7dd4601aeebbc1bbe131cbe6747476c124b47fe) List of files: /freebsd-14.2/lib/libc/tests/stdlib/Makefile

Fri, 30 Sep 2022 22:26:30 +0000

Alter the prototype of qsort_r(3) to match POSIX, which adopted theglibc-based interface.Unfortunately, the glibc maintainers, despite knowing the existenceof the FreeBSD qsort_r(3) interface in 2004 and refused to add thesame interface to glibc based on grounds of the lack of standardizationand portability concerns, has decided it was a good idea to introducetheir own qsort_r(3) interface in 2007 as a GNU extension with aslightly different and incompatible interface.With the adoption of their interface as POSIX standard, let's switchto the same prototype, there is no need to remain incompatible.C++ and C applications written for the historical FreeBSD interfaceget source level compatibility when building in C++ mode, or whenbuilding with a C compiler with C11 generics support, provided thatthe caller passes a fifth parameter of qsort_r() that exactly matchesthe historical FreeBSD comparator function pointer type and does notredefine the historical qsort_r(3) prototype in their source code.Symbol versioning is used to keep old binaries working.MFC: neverRelnotes: yesReviewed by: cem, imp, hps, pauammaDifferential revision: https://reviews.freebsd.org/D17083 List of files: /freebsd-14.2/lib/libc/tests/stdlib/Makefile

2d143336 - Enable long double tests on RISC-V

Wed, 24 Jun 2020 13:11:19 +0000

Enable long double tests on RISC-VSome of the NetBSD contributed tests are gated behind the__HAVE_LONG_DOUBLE flag. This flag seems to be defined only forplatforms whose long double is larger than their double. I could notfind this explicitly documented anywhere, but it is implied by thedefinitions in NetBSD's sys/arch/${arch}/include/math.h headers, and thefollowing assertion from the UBSAN code: #ifdef __HAVE_LONG_DOUBLE long double LD; ASSERT(sizeof(LD) > sizeof(uint64_t)); #endifRISC-V has 128-bit long doubles, so enable the tests on this platform,and update the comments to better explain the purpose of this flag.Reviewed by: ngieMFC after: 1 weekDifferential Revision: https://reviews.freebsd.org/D25419 List of files: /freebsd-14.2/lib/libc/tests/stdlib/Makefile

0eb97cca - Allow users to override CSTD/CXXSTD on a per-prog basis

Fri, 29 Mar 2019 18:49:08 +0000

Allow users to override CSTD/CXXSTD on a per-prog basisThe current logic for CSTD/CXXSTD requires homogenity as far as thesupported C/C++ standards, which is a sensible default. However, whendealing with differing versions of C++, some code may compile with C++11, butnot C++17 (for instance). So in order to avoid having people convert over theircode to the new standard, give the users the ability to specify the standard ona per-program basis.This will allow a user to override the supporting standard for a set ofprograms, mixing C++11 with C++14 (for instance).Reviewed by: asomersApprved by: emaste (mentor)MFC after: 1 monthMFC with: r345708Differential Revision: https://reviews.freebsd.org/D19738 List of files: /freebsd-14.2/lib/libc/tests/stdlib/Makefile
