[PATCH] D69288: [GISel][ArtifactCombiner] Relax the constraint to combine unmerge with concat_vectors

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: test/CodeGen/AArch64/GlobalISel/legalizer-combiner.mir:91
+    %2:_(<4 x s64>) = G_CONCAT_VECTORS %0(<2 x s64>), %1(<2 x s64>)
+    ADJCALLSTACKDOWN 0, 0, implicit-def $sp, implicit $sp
+    %3:_(s64), %4:_(s64), %5:_(s64), %6:_(s64) = G_UNMERGE_VALUES %2(<4 x s64>)
----------------
Is there a reason to have the ADJCALLSTACK?
