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

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
