--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
With checking turned on aarch64-linux-gnu:
tree VRP : 804.96 (61%) usr 0.28 ( 9%) sys 805.19 (61%) wall
35850 kB (14%) ggc
dominator optimization : 286.56 (22%) usr 0.19 ( 6%) sys 286.66 (22%) wall
24718 kB (10%) ggc
I don't have a compiler right now without checking but this seems huge even for
checking case.
