--- Comment #17 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:ee636671898c6bce63d9b2a698007b609aabbfe8 commit r16-919-gee636671898c6bce63d9b2a698007b609aabbfe8 Author: Jason Merrill <ja...@redhat.com> Date: Fri May 23 09:41:25 2025 -0400 fold: DECL_VALUE_EXPR isn't simple [PR120400] This PR noted that fold_truth_andor was wrongly changing && to & where the RHS is a VAR_DECL with DECL_VALUE_EXPR; we can't assume that such can be evaluated unconditionally. To be more precise we could recurse into DECL_VALUE_EXPR, but that doesn't seem worth bothering with since typical uses involve a COMPONENT_REF, which is not simple. PR c++/120400 gcc/ChangeLog: * fold-const.cc (simple_operand_p): False for vars with DECL_VALUE_EXPR.
