------- Comment #1 from pinskia at gcc dot gnu dot org 2010-03-09 00:34 -------
As far as I can tell this is an out of SSA issue here is a testcase which will
fail on every target I know of:
typedef float V2SF __attribute__ ((vector_size (128)));
V2SF
foo (int x, V2SF a)
{
while (x--)
a += (V2SF) {1.0f/0.0f - 1.0f/0.0f, 1.0f/0.0f - 1.0f/0.0f};
return a;
}
a's type will have a mode of BLKmode which is correct for vector types.
