--- Comment #171 from Jan Hubicka <hubicka at gcc dot gnu.org> 2013-01-16 17:25:04 UTC --- Created attachment 29182 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29182 Patch to compress line info This patch removes column information from LTO (so we lose carret diagnostics in warnings/errors output at LTO time that seems resonable thing to do) and avoid entering duplicate locators into the linemap. The patch reduces linemap usage from 23% to 5% of GGC memory saving 1-2GB on Mozilla. (also reducing LTO file size).
