[PATCH] D48791: [AArch64] Implement execute-only CodeGen Support.

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

It looks like this patch does two things:

1. Adds MC layer support for the SHF_ARM_PURECODE flag on AArch64.
2. Adds the AArch64 SHF_ARM_PURECODE flag to all sections containing code if the "execute-only" subtarget feature is enabled.

I guess nothing else is necessary because the AArch64 backend doesn't generate inline constant pools anyway?

What happens if the input IR has a mix of execute-only and non-execute-only functions?  Does the output .text section have the SHF_ARM_PURECODE flag?
