The following code:
-----------------------------------------------------------------------
typedef float V2SF __attribute__ ((vector_size (8)));
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;
}
-----------------------------------------------------------------------
produces an ICE when optimisation is enabled:
-----------------------------------------------------------------------
/tmp/foo.c: In function 'foo':
/tmp/foo.c:9: error: invalid reference prefix
