[PATCH] D102474: AArch64: support atomic load/store in GISel

[Amara Emerson via Phabricator via llvm-commits]

aemerson added inline comments.


================
Comment at: llvm/lib/CodeGen/GlobalISel/CombinerHelper.cpp:487
       // For atomics, only form anyextending loads.
       if (MMO.isAtomic() && UseMI.getOpcode() != TargetOpcode::G_ANYEXT)
         continue;
----------------
Why is this change needed? Does this line not prevent SEXTLOAD/ZEXTLOAD atomics from being formed?
