From: Billy Laws <[email protected]>
ARM64EC defines x86_64 identification macros, but its actual intrinsics
are aarch64-based. Since this
differs from what x86_64 code expects, MSVC additionally provides
softintrin.h (and softintrin.lib),
which act as wrappers to offer x86_64 variants of the intrinsics.
