Intel wrote a header that maps NEON intrinsics onto SSE to help people port to x86 Android: https://github.com/intel/ARM_NEON_2_x86_SSE

Just a heads up, as far as I know that’s more of a porting/learning tool than a production tool.

I remember us looking deeply into this and decided to hand write the SSE intrinsics. They usually map 1:1 but we had some unexpected differences in algorithm output between the x86 binary and the ARM binary when compiled with this.

But this was also back in 2019 or so, maybe it’s better now!
