commit r14-11348-g19bf2732ae4ad0c37c2493e82cc500724de746a8 Author: Iain Sandoe <iains....@gmail.com> Date: Thu Jan 30 08:19:21 2025 +0000 c++: Update const_decl handling after r15-7259 [PR118673]. Objective-C++ uses CONST_DECLs to hold constant string objects these should also be treated as mergable lvalues. PR c++/118673 gcc/cp/ChangeLog: * tree.cc (lvalue_kind): Mark CONST_DECLs as mergable when they are also TREE_STATIC.
