--- Comment #10 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?=
