Ah, thanks. I have checked mainline with -msse2, as the code you quote is
actually a sse2 code. With -msse, it crashes for all optimization levels, and
with -msse2, mainline does not ice for me.

Following code is a sse version, which compiles OK for -msse and -msse2:

typedef float v4sf __attribute__ ((vector_size (16)));

void
foo ()
{
  v4sf x = { 0.0, 0.0, 0.0, 0.0 };
  __builtin_ia32_xorpd (x, x);
}
