- Subject: SSE2 priviliged instruction exception
I couldn't find an answer on Google, so here goes:
I get a privileged instruction exception on a P4 win 2K. The same
code (and more extensive use of SSE2) executes properly on
a pentium 4 redhat 8 box. gcc is 3.2
WCPUID shows that my CPU is in fact a Pentium 4 with SSE2.
How do I get this code to work?
This is the test code:
k = _mm_setzero_ps();
and compile it with
gcc -march=pentium4 -msse2
