--- Comment #4 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:618ae596ebcd1de03857d20485d1324931852569 commit r12-160-g618ae596ebcd1de03857d20485d1324931852569 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Apr 27 15:46:16 2021 +0200 aarch64: Fix UB in the compiler [PR100200] The following patch fixes UBs in the compiler when negativing a CONST_INT containing HOST_WIDE_INT_MIN. I've changed the spots where there wasn't an obvious earlier condition check or predicate that would fail for such CONST_INTs. 2021-04-27 Jakub Jelinek <ja...@redhat.com> PR target/100200 * config/aarch64/predicates.md (aarch64_sub_immediate, aarch64_plus_immediate): Use -UINTVAL instead of -INTVAL. * config/aarch64/aarch64.md (casesi, rotl<mode>3): Likewise. * config/aarch64/aarch64.c (aarch64_print_operand, aarch64_split_atomic_op, aarch64_expand_subvti): Likewise.
