Hi there,
I was trying to compile the following source using gcc -march=pentium4 -msse2. However I get an error and am not able to understand why that is genearted.
inline void test_sse2()
{
asm(".intel_syntax noprefix \n");
asm("mov eax, DWORD PTR[seq_b_ptr] n");
asm("movupd xmm0, [eax] \n") ;
asm("mov eax, DWORD PTR[seq_a_ptr] \n");
asm("movupd xmm6, [eax]\n");
asm("movupd xmm1, mask \n");
asm("movupd xmm2, mask1\n");
asm("pand xmm6, xmm2\n");
asm("pslldq xmm6, 15\n");
asm("movupd xmm3, xmm6\n");
asm("movupd xmm4, xmm6\n");
asm("movupd xmm5, xmm6\n");
asm("emms \n") ; //switch back to FPU state.
}

uction: `popl %ebp'
Iff I put this segemnent as spart of aa laargeer codde instead of writingg it as inline, it generates sevral movl and popl errors. I dont understand what I am missing.
I know there are peoplee out there who have donee this, but i coulddnt find anything helpful using the search on gcc-help.
Thaankss,
Ganesh
