Subject: [PATCH 0/3] config/x86: improve AVX512 availability check
Date: Sat, 13 Nov 2021 00:48:23 +0300 [thread overview]
Message-ID: <20211112214826.333853-1-dmitry.kozliuk@gmail.com> (raw)
The goal of this series is to enable cross-compilation
of Windows binaries from Linux using MinGW with Meson 0.49 used in CI.
It also aims to reduce difference between Unix and Windows build code.
AVX512 was switched off for MinGW cross builds,
but unfortunately in a way that is not usable with meson 0.49.
Also, c_args was used instead of machine_args for -mno-avx512f.
After patch 3/3, AVX512 support for MinGW cross builds
is configured exactly the same way as for Unix builds.
This required rewriting a Unix-specific script in patch 2/3.
Patch 1/3 skips check of GNU binutils when LLVM suite is used:
it is useful in general [1], and also simplifies patch 2/3.
