[PATCH] D81322: [AArch64][GlobalISel] Allow G_DUP for elements smaller than 32 B.

[Amara Emerson via Phabricator via llvm-commits]

aemerson added inline comments.


================
Comment at: llvm/test/CodeGen/AArch64/GlobalISel/select-dup.mir:23
     %4:fpr(<4 x s32>) = G_DUP %0(s32)
-    $q0 = COPY %4(<4 x s32>)
-    RET_ReallyLR implicit $q0
----------------
I would prefer that we don't delete these copies, thus relying on not deleting dead instructions (which is a bit surprising to me).
