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

[Michał Górny via Phabricator via llvm-commits]

mgorny added a comment.

@ruiu, what if one of the systems changes defaults (e.g. due to Hardening) and starts defaulting to noexecstack? In that case we'd want `-z execstack' to actually emit PT_GNU_STACK, and I don't think we really are able to 100% detect the default in clang. I'd really see this as a trinary option: emit RW, emit RWX or not emit at all. I don't think it's a good idea to make linker rely on implicit assumptions or hidden guesses that could easily confuse user as to what's happening and why.
