[valgrind] [Bug 463463] none/tests/amd64/fma fails when executed under valgrind on a x86-64-v3 system
https://bugs.kde.org/show_bug.cgi?id=463463 Mark Wielaard changed: What|Removed |Added Resolution|--- |FIXED Status|REPORTED|RESOLVED --- Comment #3 from Mark Wielaard --- commit a5693c1203c3a26443af13182a8082c2e9152f6c Author: Mark Wielaard Date: Sat Apr 13 14:33:19 2024 +0200 amd64: Implement VFMADD213 for Iop_MAddF32 and Iop_MAddF64 Speed up F32 and F64 FMA on amd64. Add priv/host_amd64_maddf.c implementing h_amd64_calc_MAddF32_fma4 and h_amd64_calc_MAddF64_fma4 to be used instead of the generic variants h_generic_calc_MAddF32 and h_generic_calc_MAddF64 when host has VEX_HWCAPS_AMD64_FMA4. Add fma3 and fma4 detection m_machine.c (machine_get_hwcaps). This patch also fixes the memcheck/tests/vcpu_fnfns and none/tests/amd64/fma testcases when run on a x86-64-v3 system.

https://bugs.kde.org/show_bug.cgi?id=463463 Mark Wielaard changed: What|Removed |Added CC||m...@klomp.org --- Comment #1 from Mark Wielaard --- I am also seeing this. It seems to depend on glibc being compiled with -march=x86-64-v3. If only the fma testcase is compiled with gcc -march=x86-64-v3 but the rest of the system is not, then the testcase does pass under valgrind. -- You are receiving this mail because: You are watching all bug changes.
