SIMD intrinsics

x86 / x86-64 ARM No intrinsics fallback
✔️ ❌ (will fallback to no-intrinsics) ✔️

Intrinsics may be disabled with the no_intrinsics feature. This is the implicit behavior if SIMD intrinsics are not available on the target architecture.

Note that only sse and sse2 are enabled by default for x86 and x86-64 targets. The sse3, sse4.1, avx, fma, and avx2 intrinsics may be enabled via CPU target features.

Example: enable all x86/64 intrinsics
