The operand scanner is the problem at -O3. Richi, this is one you may want to try on the alias improvements branch, if most of the time is spent on virtual SSA names (I haven't checked, but it's likely with so many aggregate-typed variables). -- steven at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- AssignedTo|unassigned at gcc dot gnu |steven at gcc dot gnu dot |dot org |org Status|NEW |ASSIGNED Last reconfirmed|2008-12-15 21:27:40 |2008-12-16 16:26:45 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38474
