------- Comment #11 from pinskia at gcc dot gnu dot org 2008-09-18 01:00 ------- Here is a testcase which shows a missed optimization in general (on both the tree level and the RTL one) for x86 with SSE2: #define vector __attribute((vector_size(16) )) vector float a;
float f(float b)
{
vector float c = {0, 0, 0, 0};
vector float d = {0, 0, 0, 0};
d += c;
return ((float*)&c)[2];
}
