[PATCH] D138757: [zero-call-used-regs] Mark only non-debug instruction's register as used

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

Could you add a test case?



================
Comment at: llvm/lib/CodeGen/PrologEpilogInserter.cpp:1237-1239
+          if (MI.isDebugInstr())
+            continue;
+
----------------
probably makes sense to put this outside the `MI.operands()` loop, so the loop isn't even run for debug instnructions
