--- Comment #19 from Steven Bosscher <steven at gcc dot gnu.org> 2012-08-28 09:34:10 UTC --- With r190665, compile time is mostly spent in: loop doloop : 130.15 ( 8%) usr variable tracking : 990.72 (60%) usr var-tracking dataflow : 76.34 ( 5%) usr So this isn't a DF issue in GCC 4.8 at least, but yet another var-tracking issue (but probably not related to bug 53958, because var-tracking dataflow time is almost reasonable here). I'll have a look at the doloop issue, but the var-tracking issue is for Alex.
