--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Before the changes, -Walloca-larger-than wasn't enabled by default, warn_alloca_limit (and warn_vla_limit) defaulted to 0, which means e.g. pass_walloca::gate in the second pass would return false. Note, neither of these options is meant to be included in -Wall or -Wextra. But newly the options default to HOST_WIDE_INT_MAX, but the gate really hasn't been adjusted. The options weren't enabled by default before and for a good reason, so I wonder why you've changed that. I'd vote for changing their default to Init(-1) from Init(HOST_WIDE_INT_MAX) and changing back documentation, to match previous behavior.
