Project
sse2neon is a header-file project that projects can include on ARM64 platforms instead of immintrin.h. It acts as something of a drop-in replacement for SSE intrinsics, converting them to NEON intrinsics at compile-time.
There is a small test suite, which is run by executing a single EXE file.
