--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This actually reduces down to just:
unsigned char f(unsigned char a)
{
signed char d = (signed char) a;
signed char e = d & ~1;
unsigned char t = e;
t &= ~2;
return t;
}
Not reducing to:
unsigned char f1(unsigned char a)
{
return a & ~3;
}
Most likely because of the int_fits_type_p in match.pd which returns false when
switching signs. Let me look into that issue.
