--- Comment #6 from Aldy Hernandez <aldyh at gcc dot gnu.org> --- The attached patch adds a separate TV_* timer to see the actual break down for VRP and the VRP threader. Could you incorporate this patch and run the problematic file with ./cc1 -ftime-report -O2? I'd like to see the table at the end. If you're so inclined, could you also email me the entire -ftime-report so I can see the GC output as it compiles?
