--- Comment #14 from Jakub Jelinek <jakub at gcc dot gnu.org> --- By streaming the line_table directly you'd stream lots of location_t that are not actually used for anything that is streamed into the LTO. I don't understand why the tables would be huge, the string would of course use normal LTO section string sharing, and if we stream right now every location_t as the triplet, it would mean in case a single location_t is never used by more than one tree we'd stream an integer extra to what we stream now (just the triplets would be streamed in a different place), but in the more common case where one location_t is used by many trees, we'd stream less than what we stream now, due to the additional indirection.
