2023-08-29LoongArch: Add ifunc support for memrchr{lsx, lasx}dengjianbo
According to glibc memrchr microbenchmark, this implementation could reduce the runtime as following: Name Percent of rutime reduced memrchr-lasx 20%-83% memrchr-lsx 20%-64%
2023-08-29LoongArch: Add ifunc support for memchr{aligned, lsx, lasx}dengjianbo
According to glibc memchr microbenchmark, this implementation could reduce the runtime as following: Name Percent of runtime reduced memchr-lasx 37%-83% memchr-lsx 30%-66% memchr-aligned 0%-15%
2023-08-29LoongArch: Add ifunc support for rawmemchr{aligned, lsx, lasx}dengjianbo
According to glibc rawmemchr microbenchmark, A few cases tested with char '\0' experience performance degradation due to the lasx and lsx versions don't handle the '\0' separately. Overall, rawmemchr-lasx implementation could reduce the runtime about 40%-80%, rawmemchr-lsx implementation could reduce the runtime about 40%-66%, rawmemchr-aligned implementation could reduce the runtime about 20%-40%.
2023-08-29LoongArch: Micro-optimize LD_PCRELXi Ruoyao

2023-08-25m68k: Use M68K_SCALE_AVAILABLE on __mpn_lshift and __mpn_rshiftAdhemerval Zanella
This patch adds a new macro, M68K_SCALE_AVAILABLE, similar to gmp scale_available_p (mpn/m68k/m68k-defs.m4) that expand to 1 if a scale factor can be used in addressing modes. This is used instead of __mc68020__ for some optimization decisions. Checked on a build for m68k-linux-gnu target mc68020 and mc68040.
2023-08-25m68k: Fix build with -mcpu=68040 or higher (BZ 30740)Adhemerval Zanella
GCC currently does not define __mc68020__ for -mcpu=68040 or higher, which memcpy/memmove assumptions. Since this memory copy optimization seems only intended for m68020, disable for other m680X0 variants. Checked on a build for m68k-linux-gnu target mc68020 and mc68040.

2023-08-18s390x: Fix static PIE condition for toolchain bootstrapping.Stefan Liebler
The static PIE configure check uses link tests. When bootstrapping a cross-toolchain, the link tests fail due to missing crt-files / libc.so. As we explicitely want to test an issue in binutils (ld), we now also explicitely check for known linker versions.

2023-08-15malloc: Remove bin scanning from memalign (bug 30723)Florian Weimer
On the test workload (mpv --cache=yes with VP9 video decoding), the bin scanning has a very poor success rate (less than 2%). The tcache scanning has about 50% success rate, so keep that. Update comments in malloc/tst-memalign-2 to indicate the purpose of the tests. Even with the scanning removed, the additional merging opportunities since commit 542b1105852568c3ebc712225ae78b ("malloc: Enable merging of remainders in memalign (bug 30723)") are sufficient to pass the existing large bins test.
