* x86_64: Exclude SSE, AVX and FMA4 variants in libm multiarchSunil K Pandey2024-02-251-9/+12
| | | | | | | | | | | | | | | | | | | When glibc is built with ISA level 3 or higher by default, the resulting glibc binaries won't run on SSE or FMA4 processors. Exclude SSE, AVX and FMA4 variants in libm multiarch when ISA level 3 or higher is enabled by default. When glibc is built with ISA level 2 enabled by default, only keep SSE4.1 variant. Fixes BZ 31335. NB: elf/tst-valgrind-smoke test fails with ISA level 4, because valgrind doesn't support AVX512 instructions: https://bugs.kde.org/show_bug.cgi?id=383010 Reviewed-by: H.J.

I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah.

* Use ceil functions not __ceil functions in glibc libm.Joseph Myers2018-09-171-0/+1
