5205b32de3fb7702e96b3991f5b1a61eee406d8b - libc: Drop incorrect qsort optimization

Fri, 15 Aug 2025 09:22:33 +0200

libc: Drop incorrect qsort optimizationAs pointed out in the PR and the article linked below, the switch toinsertion sort in the BSD qsort code is based on a misunderstanding ofKnuth's TAOCP and is actually a pessimization. As demonstrated by theadded test, it is trivially easy to construct pathological input whichresults in quadratic runtime. Without that misguided optimization, thesame input runs in nearly linearithmic time.https://www.raygard.net/2022/02/26/Re-engineering-a-qsort-part-3PR: 287089MFC after: 1 weekReviewed by: impDifferential Revision: https://reviews.freebsd.org/D51907 List of files: /freebsd/lib/libc/tests/stdlib/Makefile

Tue, 22 Apr 2025 19:16:59 +0200

fts: Add blocks support.This adds an `fts_open_b()` variant of `fts_open()` which takes a blockinstead of a function pointer.This was inspired by, and is intended to be compatible with, Apple'simplementation; however, although our FTS and theirs share a commonancestor, they have diverged significantly. That and the fact thatwe still target compilers which don't support blocks means Apple'simplementation was not directly reusable.This is the second use case for blocks in FreeBSD (the first being`qsort_b()`, which we use here). This suggest we might want to adda `COMPILER_FEATURE` for blocks to avoid hardcoding any further`COMPILER_TYPE` checks.MFC after: neverRelnotes: yesSponsored by: Klara, Inc.Reviewed by: kevans, theraven, impDifferential Revision: https://reviews.freebsd.org/D49877 List of files: /freebsd/lib/libc/tests/stdlib/Makefile

6527682ab7058e5023a2a6dea01d51c15dca701f - src: Use gnu++17 as the default C++ standard

Fri, 11 Apr 2025 15:53:50 +0200

src: Use gnu++17 as the default C++ standardPreviously the compiler's default C++ standard was used unlike C wherebsd.sys.mk explicitly sets a default language version. Setting anexplicit default version will give a more uniform experience acrossdifferent compilers and compiler versions.gnu++17 was chosen to match the default C standard. It is wellsupported by a wide range of clang (5+) and GCC (9+) versions.gnu++17 is also the default C++ standard in recent versions of clang(16+) and GCC (11+). As a result, many of the explicit CXXSTDsettings in Makefiles had the effect of lowering the C++ standardinstead of raising it as was originally intended and are removed.Note that the remaining explicit CXXSTD settings for atf and liblutokexplicitly lower the standard to C++11 due to use of the deprecatedauto_ptr<> template which is removed in later versions.Reviewed by: imp, asomers, dim, emasteDifferential Revision: https://reviews.freebsd.org/D49223 List of files: /freebsd/lib/libc/tests/stdlib/Makefile

Sat, 01 Oct 2022 00:26:30 +0200

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/lib/libc/tests/stdlib/Makefile

2d143336dec8a43803bfba507c5f29a625bc4137 - Enable long double tests on RISC-V

Wed, 24 Jun 2020 15:11:19 +0200

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/lib/libc/tests/stdlib/Makefile
