[PATCH] D57399: AMDGPU/GlobalISel: Add support for wide loads >= 256-bits

[Tom Stellard via Phabricator via llvm-commits]

tstellar updated this revision to Diff 208820.
tstellar added a comment.

I added a better comment to getOtherVRegDef.  I tried to come up with
a solution using the OperandsMapper, but in the end I had to implement
something similar to getOtherVRegDef to in order to verify that we retreived the
correct LegalizedInst from the LegalizeHelper.  It was also way more code and
might be more confusing.  Hopefully the new comment on getOtherVRegDef makes
it clear what is going on.
