So When I try to compile such code
#include <iostream>
#include <time.h>
#include <stdlib.h>
#include <math.h>
#include <emmintrin.h>
int main()
{
double s_ptime = clock();
double d1 = 0;
double d2 = 1;
double d3 = 1;
__m128d pd, pd2;
pd = _mm_loadh_pd(pd, &d1);
pd = _mm_loadl_pd(pd, &d2);
pd2 = _mm_loadh_pd(pd2, &d3);
pd2 = _mm_loadl_pd(pd2, &d3);
for(long i=0; i<10000000000; i++){
pd = _mm_sub_pd(pd, pd2);
};
_mm_storeh_pd(&d1, pd);
_mm_storel_pd(&d2, pd);
double ptime = (clock() - s_ptime); //CLOCKS_PER_SEC;
std::cout << "\t cpu: " << ptime << " " << d1 <<" " << d2 << "
tics\n";
};
with command
g++43 -mfpmath=sse -msse -msse2 -o testsse testsse.cc -mstackrealign
I have such message
/usr/local/lib/gcc-4.3.2/include/c++//x86_64-portbld-freebsd7.0/bits/gthr-default.h:
