commit b7fab6f285ff0ff3816b109a8c3131b6ded0b484
Author: edo <edo....@gmail.com>
Date: Wed Oct 7 08:33:57 2020 +0300
Allow cross-compilation with SIMD (x86_84) (#104)
Replace runtime SIMD check with a compile-only test in case of
cross-compilation.
You can still use '--enable-simd=no' to build x86_64 code without
SIMD instructions.
