--- Comment #8 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Martin Jambor <jamb...@gcc.gnu.org>: https://gcc.gnu.org/g:d019ab4f115caab48316c185c007765719e93052 commit r15-6769-gd019ab4f115caab48316c185c007765719e93052 Author: Martin Jambor <mjam...@suse.cz> Date: Sat Jan 4 20:40:07 2025 +0100 ipa-cp: Fold-convert values when necessary (PR 118138) PR 118138 and quite a few duplicates that it has acquired in a short time show that even though we are careful to make sure we do not loose any bits when newly allowing type conversions in jump-functions, we still need to perform the fold conversions during IPA constant propagation and not just at the end in order to properly perform sign-extensions or zero-extensions as appropriate. This patch does just that, changing a safety predicate we already use at the appropriate places to return the necessary type. gcc/ChangeLog: 2025-01-03 Martin Jambor <mjam...@suse.cz> PR ipa/118138 * ipa-cp.cc (ipacp_value_safe_for_type): Return the appropriate type instead of a bool, accept NULL_TREE VALUEs. (propagate_vals_across_arith_jfunc): Use the new returned value of ipacp_value_safe_for_type. (propagate_vals_across_ancestor): Likewise. (propagate_scalar_across_jump_function): Likewise. gcc/testsuite/ChangeLog: 2025-01-03 Martin Jambor <mjam...@suse.cz> PR ipa/118138 * gcc.dg/ipa/pr118138.c: New test.
