<pre>The following code causes trunk clang (and previous versions) to crash with
'cannot select'.
typedef float __m128 __attribute__((__vector_size__(16)));
__m128 foo(float value) {
__m128 t;
asm("":"=x"(t):"0"(value));
return t;
}
Error:
fatal error: error in backend: Cannot select: 0x55d249ef7378: v4f32,ch =
load<LD4[%2](dereferenceable), anyext from f32> 0x55d249ef7720,
FrameIndex:i64<0>, undef:i64
0x55d249ef76b8: i64 = FrameIndex<0>
