A C/C++ header file that converts Intel SSE intrinsics to MIPS/MIPS64 MSA intrinsics.
Inspired by sse2neon, sse2msa translates Intel SSE (Streaming SIMD Extensions) intrinsics to MIPS MSA.
| Header file | Extension |
|---|---|
<mmintrin.h> |
MMX |
<xmmintrin.h> |
SSE |
<emmintrin.h> |
SSE2 |
<pmmintrin.h> |
SSE3 |
<tmmintrin.h> |
SSSE3 |
<smmintrin.h> |
SSE4.1 |
<nmmintrin.h> |
SSE4.2 |
sse2msa aims to support SSE, SSE2, SSE3, SSSE3, SSE4.1 and SSE4.2 extension.
The header file sse2msa.h provides "SSE intrinsics" implemented with MSA intrinsics, on MIPS/MIPS64 targets, here's a example:
#include <stdio.h>
#if defined(__x86_64)
#include <xmmintrin.h>
#elif defined(__mips)
#include "sse2msa.h"
#endif
#define NELEM_F32 (sizeof(__m128) / sizeof(float))
int main()
{
float out[NELEM_F32];
__m128 a = _mm_set_ps1(1.0);
_mm_storeu_ps(out, _mm_add_ps(a, a));
for (int i = 0; i < NELEM_F32; ++i) {
printf("%f\t", out[i]);
}
putc('\n', stdout);
return 0;
}On MIPS/MIPS64 targets, append the following compiler option:
-mmsa- sse2neon: A C/C++ header file that converts Intel SSE intrinsics to Arm/Aarch64 NEON intrinsics.
- SIMDe: Fast and portable implementations of SIMD intrinsics on hardware which doesn't natively support them, such as calling SSE functions on ARM.
