[PATCH] D29813: [DAGCombiner] Fix DebugLoc propagation when folding !(x cc y) -> (x !cc y)

[Adrian Prantl via Phabricator via llvm-commits]

aprantl added inline comments.


================
Comment at: test/CodeGen/X86/xor-combine-debugloc.ll:2
+; RUN: llc < %s | FileCheck %s
+;
+; CHECK: foo:x <- %EDI
----------------
Please add a comment that explains what is being checked here.
It might be more robust to run llc -stop-after=.. and check the MIR right after ISEL.
