This question is not appropriate for the gcc@gcc.gnu.org mailing list,
which is for the development of gcc itself. It would be appropriate on
gcc-h...@gcc.gnu.org. Please take any followups to g
Can somebody please explain the behavior of the following program
to me?
cat >test.c <
#include
#include
int main(void){
register __m128 var;
fprintf(stdout,"pre %X\n",var);
var = _mm_setzero_ps();
fprintf(stdout,"post %X\n",var);
fprintf(stdout,"zerof %X\n",0.0f);
exit(EXIT_SU
I'm seeing the oddest thing with a function compiled like:
mpicc -std=gnu99 -O1 -g -m32 -pthread -msse -mno-sse2 -DHAVE_CONFIG_H
-I../../easel -I../../easel -I. -I.. -I. -I../../src -o fwdback.o -c
fwdback.c
using both gcc versions
gcc (GCC) 4.4.1 (on a 64 bit linux)
gcc (GCC) 4.2.3 (4.2.3-6m
