[PATCH] D80258: Fix SourceMgrDiagnosticHandler::convertLocToSMLoc for unknown line/column scenerio.

[Mehdi AMINI via Phabricator via llvm-commits]

mehdi_amini added inline comments.


================
Comment at: mlir/lib/IR/Diagnostics.cpp:515
+  if (loc.getLine() == 0 || loc.getColumn() == 0)
+    return llvm::SMLoc();
+
----------------
How do we actually identify when the loc is referring really to the beginning of the file? There isn't a way to figure out?
