--- Comment #4 from ktkachov at gcc dot gnu.org ---
Hmmm...
int main (void)
{
int a = 0;
unsigned b = (a * 64 & 192) | 63;
return 0;
}
works (i.e. 63 without the U).
I suspect there's something dodgy with the implementation of
mask_with_tz (tree type, double_int x, double_int y) in fold-const.c that I
added with r202652.
Interestingly, the wide-int branch that rewrites that function to use the new
wide-int interface makes this ICE go away.
