[Jason Liu via Phabricator via llvm-commits]

jasonliu added inline comments.


================
Comment at: llvm/lib/Target/PowerPC/PPCISelLowering.cpp:5287
-    // If there exists a user-declared function whose name is the same as the
-    // ExternalSymbol's, then we pick up the user-declared version.
-    const Module *Mod = DAG.getMachineFunction().getFunction().getParent();

Please consider the case in llvm/test/CodeGen/PowerPC/aix-user-defined-memcpy.ll
