@item max-inline-insns-single
-@item max-inline-insns-single-O2
Several parameters control the tree inliner used in GCC@. This number sets the
maximum number of instructions (counted in GCC's internal representation) in a
single function that the tree inliner considers for inlining. This only
affects functions declared inline and methods implemented in a class
declaration (C++).
-For functions compiled with optimization levels
-@option{-O3} and @option{-Ofast} parameter @option{max-inline-insns-single} is
-applied. In other cases @option{max-inline-insns-single-O2} is applied.
-
@item max-inline-insns-auto
When you use @option{-finline-functions} (included in @option{-O3}),
execute function prologue and epilogue
@item inline-heuristics-hint-percent
-@item inline-heuristics-hint-percent-O2
The scale (in percents) applied to @option{inline-insns-single},
@option{inline-insns-single-O2}, @option{inline-insns-auto}
when inline heuristics hints that inlining is
very profitable (will enable later optimizations).
-For functions compiled with optimization levels
-@option{-O3} and @option{-Ofast} parameter
-@option{inline-heuristics-hint-percent} is applied. In other cases
-@option{inline-heuristics-hint-percent-O2} is applied.
-
@item uninlined-thunk-insns
@item uninlined-thunk-time
Same as @option{--param uninlined-function-insns} and
@option{--param uninlined-function-time} but applied to function thunks
@item inline-min-speedup
-@item inline-min-speedup-O2
When estimated performance improvement of caller + callee runtime exceeds this
threshold (in percent), the function can be inlined regardless of the limit on
@option{--param max-inline-insns-single} and @option{--param
max-inline-insns-auto}.
-For functions compiled with optimization levels
-@option{-O3} and @option{-Ofast} parameter @option{inline-min-speedup} is
-applied. In other cases @option{inline-min-speedup-O2} is applied.
-
@item large-function-insns
The limit specifying really large functions. For functions larger than this
limit after inlining, inlining is constrained by
expressions whose probability exceeds the given threshold (in percents).
@item early-inlining-insns
-@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.
-For functions compiled with optimization levels
-@option{-O3} and @option{-Ofast} parameter @option{early-inlining-insns} is
-applied. In other cases @option{early-inlining-insns-O2} is applied.
-
@item max-early-inliner-iterations
Limit of iterations of the early inliner. This basically bounds
the number of nested indirect calls the early inliner can resolve.
