--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Tue Dec 10 21:04:08 2019 New Revision: 279193 URL: https://gcc.gnu.org/viewcvs?rev=279193&root=gcc&view=rev Log: PR middle-end/92825 * cfgexpand.c (add_stack_protection_conflicts): Change return type from void to bool, return true if at least one stack_vars[i].decl is addressable. (record_or_union_type_has_array_p, stack_protect_decl_p): Remove. (expand_used_vars): Don't call stack_protect_decl_p, instead for -fstack-protector-strong set gen_stack_protect_signal to true if add_stack_protection_conflicts returned true. Formatting fixes. * doc/invoke.texi (-fstack-protector-strong): Clarify that optimized out variables or variables not living on the stack don't count. (-fstack-protector): Likewise. Clarify it affects >= 8 byte arrays rather than > 8 byte. * gcc.target/i386/pr92825.c: New test. Added: trunk/gcc/testsuite/gcc.target/i386/pr92825.c Modified: trunk/gcc/ChangeLog trunk/gcc/cfgexpand.c trunk/gcc/doc/invoke.texi trunk/gcc/testsuite/ChangeLog
