--- Comment #2 from Julian Seward <jsew...@acm.org> ---
I can't reproduce this. Are you sure this is right? I tried
thusly:
int main ( void )
{
__asm__ __volatile__(
".byte 0xC5, 0xFA, 0x7F, 0x45, 0x80, 0xC5, 0xFA, 0x7F, 0x4D, 0x90"
::: "cc","memory");
return 0;
}
giving
00000000004004f6 <main>:
4004f6: c5 fa 7f 45 80 vmovdqu %xmm0,-0x80(%rbp)
4004fb: c5 fa 7f 4d 90 vmovdqu %xmm1,-0x70(%rbp)
400500: b8 00 00 00 00 mov $0x0,%eax
400505: c3 retq
400506: 66 2e 0f 1f 84 00 00 nopw %cs:0x0(%rax,%rax,1)
40050d: 00 00 00
(sure, there are 2 complete insns there, but it doesn't matter)
and although it segfaults (as it does natively), it runs correctly
through the front end:
$ ./zzz6
