middle-end/110176 - wrong zext (bool) <= (int) 4294967295u folding
The following fixes a wrong pattern that didn't match the behavior
of the original fold_widened_comparison in that get_unwidened
returned a constant always in the wider type. But here we're
using (int) 4294967295u without the conversion applied. Fixed
by doing as earlier in the pattern - matching constants only
if the conversion was actually applied.
PR middle-end/110176
* match.pd (zext (bool) <= (int) 4294967295u): Make sure
to match INTEGER_CST only without outstanding conversion.
* gcc.dg/torture/pr110176.c: New testcase.
