[PATCH] D129693: [ARM] Don't emit Arm speculation hardening thunks under Thumb and vice-versa

[Dave Green via Phabricator via llvm-commits]

dmgreen updated this revision to Diff 451167.
dmgreen added a comment.

The old version of this was only inserting one set of thunks even if the file contained multiple subtargets. This now uses InsertedThunks as a bitvector to distinguish between Thumb and Arm thunks being added. It should still only add each thunk once, but won't add both sets (arm/thumb) if they are not required.
