@ -11291,9 +11291,17 @@ recursion depth can be guessed from the probability that function recurses
via a given call expression. This parameter limits inlining only to call
expressions whose probability exceeds the given threshold (in percents).
@item early-inlining-insns-O2
Specify growth that the early inliner can make. In effect it increases
the amount of inlining for code having a large abstraction penalty.
This is applied to functions compiled with @option{-O1} or @option{-O2}
optimization levels.
@item early-inlining-insns
Specify growth that the early inliner can make. In effect it increases
the amount of inlining for code having a large abstraction penalty.
This is applied to functions compiled with @option{-O3} or @option{-Ofast}
optimization levels.
@item max-early-inliner-iterations
Limit of iterations of the early inliner. This basically bounds
