Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dmalcolm at gcc dot gnu.org, | |jakub at gcc dot gnu.org --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The compiler represents locations and even location ranges as 32-bit integers, so for normally sized sources can encode both line and column and range information, but with too many columns or lines gradually loses the ranges/column information and later the line information as well. Will defer to David for details.
