--- Comment #5 from pcpa <paulo.cesar.pereira.de.andr...@gmail.com> --- It should be tricky to figure what version is being used. Could look into the 'the elf_machine_runtime_setup' function in sysdeps/${ARCH}/dl-machine.h glibc source. Sample chunk from rhel7 x86_64 source: ... if (HAS_ARCH_FEATURE (AVX512F_Usable)) *(ElfW(Addr) *) (got + 2) = (ElfW(Addr)) &_dl_runtime_profile_avx512; else if (HAS_ARCH_FEATURE (AVX_Usable)) *(ElfW(Addr) *) (got + 2) = (ElfW(Addr)) &_dl_runtime_profile_avx; else *(ElfW(Addr) *) (got + 2) = (ElfW(Addr)) &_dl_runtime_profile_sse; ... because of check for cpu features, a reproducer environment to validate all entries, or experiment with automatic detection might need custom VMs. -- You are receiving this mail because: You are watching all bug changes.
