[PATCH] D91921: [ARM] Introduce MVETRUNC ISel lowering

[Sam Tebbs via Phabricator via llvm-commits]

================
Comment at: llvm/lib/Target/ARM/ARMISelLowering.h:140
 
+      MVETRUNC,     // Legalization aid for truncating two vectors into a single.

----------------
Can we instead delay the splitting of a truncate instead of coining a new node for it? I suppose that future stages in the pipeline may depend on it being legal so the splitting would have to happen early.
