--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
With plain -O1 we also get
alias stmt walking : 14.78 (19%) usr 0.10 ( 6%) sys 14.90 (19%) wall
0 kB ( 0%) ggc
tree SSA incremental : 31.81 (41%) usr 0.01 ( 1%) sys 31.82 (40%) wall
6645 kB ( 1%) ggc
ick. Similar to old KDE testcases with a very big initializer function.
Here it is 30000 lines gli_init_gl_entrypoint_descs (I suppose auto-generated).
>From a quick look it's a single gigantic basic-block doing a sequence of
global stores.
