[Karl-Johan Karlsson via Phabricator via llvm-commits]

Ka-Ka added inline comments.


================
Comment at: lib/CodeGen/RegisterCoalescer.cpp:1322-1324
+        // Move the debug value directly after the def of the rematerialized
+        // value in DstReg.
+        MBB->splice(std::next(NewMI.getIterator()), UseMI->getParent(), UseMI);
----------------
The alternative to moving the debug value is to remove it.
