Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|c |middle-end Keywords| |wrong-code Last reconfirmed| |2021-06-09 Ever confirmed|0 |1 Status|UNCONFIRMED |WAITING --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- So the tree level looks fine for me: _1 = (unsigned int) i_5(D); _2 = -_1; _9 = (unsigned int) m_6(D); _3 = _2 & _9; _4 = _3 - _1; _7 = (int) _4; ---- CUT ---- This is for: int f (long int m, long int i) { return ((m & ~(i - 1)) - i); } ---- CUT ---- The assembly produced for both x86_64 and aarch64 looks correct. What target is this on?
