2022-03-28x86: Small improvements for wcslenNoah Goldstein1-45/+41
Just a few QOL changes. 1. Prefer `add` > `lea` as it has high execution units it can run on. 2. Don't break macro-fusion between `test` and `jcc` 3. Reduce code size by removing gratuitous padding bytes (-90 bytes). geometric_mean(N=20) of all benchmarks New / Original: 0.959 All string/memory tests pass. Reviewed-by: H.J.

2022-03-25x86: Remove AVX str{n}casecmpNoah Goldstein6-197/+105
The rational is: 1. SSE42 has nearly identical logic so any benefit is minimal (3.4% regression on Tigerlake using SSE42 versus AVX across the benchtest suite). 2. AVX2 version covers the majority of targets that previously prefered it. 3. The targets where AVX would still be best (SnB and IVB) are becoming outdated. All in all the saving the code size is worth it. All string/memory tests pass. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>

Overflow case for __wcsncmp_avx2_rtm should be __wcscmp_avx2_rtm not __wcscmp_avx2. commit ddf0992cf57a93200e0c782e2a94d0733a5a0b87 Author: Noah Goldstein <goldstein.w.n@gmail.com> Date: Sun Jan 9 16:02:21 2022 -0600 x86: Fix __wcsncmp_avx2 in strcmp-avx2.S [BZ# 28755] Set the wrong fallback function for `__wcsncmp_avx2_rtm`. It was set to fallback on to `__wcscmp_avx2` instead of `__wcscmp_avx2_rtm` which can cause spurious aborts. This change will need to be backported. All string/memory tests pass. Reviewed-by: H.J.

2022-03-25benchtests: Add random benchmark in bench-strchr.cNoah Goldstein1-0/+143
Add benchmark that randomizes whether return should be NULL or pointer to CHAR. The rationale is on many architectures there is a choice between a predicate execution option (i.e cmovcc on x86) or a branch. On x86 the results for cmovcc vs branch are something along the lines of the following: perc-zero, Br On Result, Time Br / Time cmov 0.10, 1, ,0.983 0.10, 0, ,1.246 0.25, 1, ,1.035 0.25, 0, ,1.49 0.33, 1, ,1.016 0.33, 0, ,1.579 0.50, 1, ,1.228 0.50, 0, ,1.739 0.66, 1, ,1.039 0.66, 0, ,1.764 0.75, 1, ,0.996 0.75, 0, ,1.642 0.90, 1, ,1.071 0.90, 0, ,1.409 1.00, 1, ,0.937 1.00, 0, ,0.999 Reviewed-by: H.J.

2022-03-22configure.ac: fix bashisms in configure.acSam James6-6/+6
configure scripts need to be runnable with a POSIX-compliant /bin/sh. On many (but not all!) systems, /bin/sh is provided by Bash, so errors like this aren't spotted. Notably Debian defaults to /bin/sh provided by dash which doesn't tolerate such bashisms as '=='. This retains compatibility with bash. Fixes configure warnings/errors like: ``` checking if compiler warns about alias for function with incompatible types... yes /var/tmp/portage/sys-libs/glibc-2.34-r10/work/glibc-2.34/configure: 4209: test: xyes: unexpected operator ``` Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org> Signed-off-by: Sam James <sam@gentoo.org>
