--- Comment #8 from Daniel Berlin <dberlin at gcc dot gnu.org> 2012-03-05 17:20:36 UTC --- I still have an unfinished patch to convert SCCVN to http://dl.acm.org/citation.cfm?id=512536 This actually makes it significantly easier to integrate better congruence finding (and lets us use predicates properly during value numbering). It also was significantly faster in large functions (also functiojns containing large SCC's) due to a significantly better iteration strategy (it will only iterate values that are changing, while SCCVN will iterate all values in an SCC). I'm happy to attach the patch if you like :) On Sat, Mar 3, 2012 at 7:45 PM, pinskia at gcc dot gnu.org <gcc-bugzi...@gcc.gnu.org> wrote: > http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32120 > > --- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> 2012-03-04 > 00:45:50 UTC --- > I might even have a patch for my tree combine branch later today.
