I've also got problem with MySQL on EMT64, I've reported it as #76858 Also the mentioned test program generates on SIGILL on that machine, but not on AMD64.

[Bug 66702] Re: GCC emits 3DNow!-specific instruction for __builtin_prefetch
Hi,
Using this simple test program:
int
main (int argc, char *argv[])
{
int i;
int test[8];
__builtin_prefetch (test, 1);
for (i = 0; i < 8; i++)
{
test[i] = i;
}
return 0;
}
And compiling using gcc -S test.c, the generated .s file includes the following
assembly code:
.LCFI1:
movl%edi, -52(%rbp)
movq%rsi, -64(%rbp)
leaq-48(%rbp), %rax
prefetchw (%rax)
movl$0, -4(%rbp)
jmp .L2
.L3:
prefetchw is a 3Dnow! instruction, not available on EMT64.
