[PATCH] D120989: Support debug info for alias variable

[David Blaikie via Phabricator via cfe-commits]

dblaikie added a comment.

I think it'd potentially go somewhere in `DWARFDebugLine::LineTable::getFileLineInfoForAddress` for instance - which could inspect the candidate row in the line table, and if it's line zero, it could go back one row in the table. This would avoid probing addresses that are defined by the same row and will have the same result. (& could keep going back rows until it finds a non-zero row) & document that it's a fuzzy match. Or always produce the precise result and a separate non-zero fuzzy result if the main result is zero. "Nearest preceeding non-zero" or something.
