[PATCH] D142019: ARM: skip debug instructions when matching jump-table patterns.

[Jeremy Morse via Phabricator via llvm-commits]

jmorse added inline comments.


================
Comment at: llvm/lib/Target/ARM/ARMConstantIslandPass.cpp:2282-2284
+      do {
+        Shift = Shift->getPrevNode();
+      } while (Shift && Shift->isDebugInstr());
----------------
I believe you should be able to use `skipDebugInstructionsBackward` to achieve this more concisely.
