--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The numbers I got is that something grew up a little bit, something shrunk a little bit, sometimes .debug_info grew up and .debug_loc shrunk, sometimes the other way around, but in general it wasn't significant. Debug info size growth in itself is not something bad if it means better variable location coverage, on the other size shrinking is something bad if it means fewer variables are covered or on a smaller set of instructions.
