Hi! Some time ago I've changed const_binop -> wide_int_binop, so that it punts on shifts by negative count. fold_truth_andor_1 doesn't check the results of const_binop (?SHIFT_EXPR, ) though and assumes they will be always non-NULL, which is no longer the case. Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk? 2021-12-28 Jakub Jelinek <ja...@redhat.com> PR middle-end/103813 * fold-const.c (fold_truth_andor_1): Punt of const_binop LSHIFT_EXPR or RSHIFT_EXPR returns NULL. Formatting fix. * gcc.c-torture/compile/pr103813.c: New test.
OK jeff
