[PATCH] D124834: [fastregalloc] Fix bug when undef value is tied to def.

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added inline comments.


================
Comment at: llvm/lib/CodeGen/RegAllocFast.cpp:1118
+    unsigned TiedIdx = MI.findTiedOperandIdx(Idx);
+    auto TiedMO = MI.getOperand(TiedIdx);
+    return TiedMO.isUndef();
----------------
Please avoid `auto` when the type isn't immediately visible within the same line, it makes the code easier to read. See https://llvm.org/docs/CodingStandards.html#use-auto-type-deduction-to-make-code-more-readable
