Steven Bosscher <steven at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |steven at gcc dot gnu.org --- Comment #3 from Steven Bosscher <steven at gcc dot gnu.org> 2013-03-03 00:57:04 UTC --- Can you add a few options and report back the reports? You can add -ftime-report to the command line to let the compiler dump a report about how much time it spent in different parts of the compiler. With your observation about cselib, I suspect this is another issue with the scalability of var-tracking. Can you try with -g -fno-var-tracking?
