[PATCH] D126085: [RISCV] Add a subtarget feature to enable unaligned scalar loads and stores

[Philip Reames via Phabricator via llvm-commits]

reames added a comment.

The topic of Tag_RISCV_unaligned_access handling was discussed in today's risc-v sync up call.  The conclusion of that discussion is that we're going to leave it unset in this patch, and that I'm going to file an issue against the psABI to clarify a couple points in the spec.  Once that clarification has been done, we may revisit setting the tag.

In the short run, we believe that leaving the tag in the unset state is the lowest risk strategy, and the least likely to break assumptions which may have been made about the meaning of the tag.
