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.
