--- Comment #49 from Jakub Jelinek <jakub at gcc dot gnu.org> --- On the other side, we don't turn -fno-omit-frame-pointer or -mno-omit-leaf-frame-pointer for -fsanitize=address on other targets either, perhaps this is just a documentation issue. I'll add -mbackchain to this testcase. Perhaps we should just mention those flags in -fsanitize=address documentation in invoke.texi.
