--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:9258ac53cfcbe546e8b86a433e59343538743f74 commit r12-6135-g9258ac53cfcbe546e8b86a433e59343538743f74 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Dec 28 17:41:24 2021 +0100 fold-const: Fix up fold_truth_andor_1 shift handling [PR103813] 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. 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.
