--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Alexandre Oliva <aol...@gcc.gnu.org>: https://gcc.gnu.org/g:fb488cba571539b6644e8f99f1dd997cdb4c82c1 commit r12-7801-gfb488cba571539b6644e8f99f1dd997cdb4c82c1 Author: Alexandre Oliva <ol...@adacore.com> Date: Thu Mar 24 10:02:29 2022 -0300 hardened conditionals: drop copied identifiers The copies of identifiers, indended to associate hardening SSA temporaries to the original variables they refer to, end up causing -fcompare-debug to fail, because DECL_UIDs are not identical, and the nouid flag used in compare-debug dumps doesn't affect the uids in naked identifiers, so the divergence becomes apparent. This patch drops the naked identifiers. Though somewhat desirable, they're not necessary. for gcc/ChangeLog PR debug/104564 * gimple-harden-conditionals.cc (detach_value): Keep temps anonymous. for gcc/testsuite/ChangeLog PR debug/104564 * c-c++-common/torture/harden-comp.c: Adjust. * c-c++-common/torture/harden-cond.c: Adjust.
