Ok, that makes sense.  Until the front-ends all get updated, they can
always just provide 0 as the column number to preserve current behavior...

Right, but they still have to be updated to request a source_location from the global line_table since that would be the new type of input_location, DECL_LOCUS, etc. A few well-chosen macros should make that easy. Note that input_line would no longer be an lvalue but an rvalue-only macro that may call a function. -- --Per Bothner per@bothner.com http://per.bothner.com/
