https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: sci-libs/blis-0.6.0 fails to compile. Discovered on: amd64 (internal ref: ci)
Created attachment 683407 [details] build.log build log and emerge --info
Possible context of error(s): /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/include/fmaintrin.h:63:1: error: inlining failed in call to ‘always_inline’ ‘_mm256_fmadd_ps’: target specific option mismatch
This was caused by cpu autodetection (detected as skx) with manual specification of `-march=x86-64` in CFLAGS. I'll update ebuild to disable autodetection and rely on CPU_FLAGS_* USE_EXPAND flags.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=9d5cefbcb6fdcfe5deb2f679b27f8b510c18c7c9 commit 9d5cefbcb6fdcfe5deb2f679b27f8b510c18c7c9 Author: Sv.

Note that while cpu_flags_*-based configuration resembles automatic one, it is not fully the same. For example, there are 2 types of Skylake CPUs: with 1 or 2 FMA units. Attempt to enable cpu_flags_x86_avx512vl on CPUs with 1 FMA unit will result in reduced performance. Previously this was handled by automatic detection of 1FMA Skylake as Haswell; now user should not specify cpu_flags_x86_avx512vl if CPU has degraded AVX-512 support.
