[PATCH] D56554: [ELF] Add '-z nognustack' opt to suppress emitting PT_GNU_STACK

[Rui Ueyama via Phabricator via cfe-commits]

ruiu added a comment.

The absence of PT_GNU_STACK segment makes stack area executable on systems that recognizes PT_GNU_STACK segment. So, I think if `-z execstack` is specified, we should omit PT_GNU_STACK segment rather than adding it, which I think you guys want. If we do that, it seems `-z nognustack` is a redundant option. That option name is unfortunate (you don't really mean you want an executable stack area), but that's I think still better than adding an option that is very similar to an existing feature.
