<pre>Sample code:
#include <xmmintrin.h>
void foo(void)
{
__m128 x;
asm("" : "=x" (x));
}
If this is compiled with "clang -m32 -march=athlon-xp", the result is:
fatal error: error in backend: Do not know how to split the result of this
operator!
Apparently athlon-xp does support SSE, so this is likely a bug somewhere.</pre>
