------- Comment #1 from jakub at gcc dot gnu dot org 2009-02-19 13:16 -------
Reduced testcase:
static inline int
foo (float f)
{
return *((int *) &f) - 1;
}
float
bar (float x, float y, float *z)
{
float c = y < 0.002f ? 0.002f : y;
float d = x < c ? c : x;
return z[foo (c)] + z[foo (d * 255.0f)];
}
