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

[Jing Pu via Phabricator via llvm-commits]

Jing added a comment.

I found there are some internal tests (on diagnostics) that rely on column zero being the first column.
I am not so sure whether we should adopt that behavior and change API (i.e. treating only row zero being an unknown location) or fix the tests.
