# transparently select the fastest for the current hardware.
# This feature is only available on linux for x86, x86_64, and aarch64.

# If FAT_RUNTIME is not available, we fall back to building for a single extension based
# on stdenv.hostPlatform.
#
# For generic builds (e.g. x86_64) this can mean using an implementation not optimized for the
# potentially available more modern hardware extensions (e.g. x86_64 with AVX512).
