[Hideto Ueno via Phabricator via llvm-commits]

uenoku added inline comments.


================
Comment at: llvm/lib/Transforms/IPO/Attributor.cpp:597-598
+    const IRPosition &ACSArgPos = IRPosition::callsite_argument(ACS, ArgNo);
+    // Check if a coresponding argument was found or if it is on not associated
+    // (which can happen for callback calls).
+    if (ACSArgPos.getPositionKind() == IRPosition::IRP_INVALID)
----------------
I couldn't understand this. Could you show me an example?
