Well, if H.J.'s proposed backport of the builtin cost sizes helps, I guess it
is sane
way to fix this. I will take a look why main inliner don't do the job when
early inliner
ignores the call.
I am not sure how much of heuristics changes makes sense to backport to 4.5.
Depends on importance
of the regression I guess.
