Today we regressed with the introduction of IPA-SRA at -O2 and -O3:
ipa SRA : 387.53 (78%) usr 0.08 ( 5%) sys 387.79 (77%) wall
2939 kB ( 1%) ggc
my bet is at the alias-oracle walking (walk_aliased_vdefs), which is not
properly limited.
with VTA introduction we regressed at -O1 -g:
variable tracking : 592.31 (91%) usr 1.06 (48%) sys 593.55 (91%) wall
239922 kB (34%) ggc
