[arm] Distinguish the /U[qytnms]/, 'Uv', 'Q', and 'm' inline assembly memory constraints.

Authored by dsanders on Mar 10 2015, 7:49 AM.



But still handle them the same way since I don't know how they differ on
this target.

Of these, /U[qytnms]/ do not have backend tests but are accepted by clang.

No functional change intended. Depends on D8173.

Added the missing portion of the patch which handled /U[qytnms]/


The main thing I'm looking for is for is for someone with knowledge of the target to say whether they're aware of any supported constraints that this patch doesn't cover.

Sorry for the delay. This looks fine to me. If anything I'd be inclined to drop the ones not documented by GCC, but that's more of a policy debate we can have when someone feels strongly enough about it.
