sse2msa

A C/C++ header file that converts Intel SSE intrinsics to MIPS/MIPS64 MSA intrinsics.

Introduction

Inspired by sse2neon, sse2msa translates Intel SSE (Streaming SIMD Extensions) intrinsics to MIPS MSA.

Mapping and Coverage

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.

Example

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
