This parameter is useful primarily to avoid extreme compilation time caused by non-linear

The limit specifying really large functions. For functions larger than this
limit after inlining inlining is constrained by
@option{--param large-function-growth}. This parameter is useful primarily
to avoid extreme compilation time caused by non-linear algorithms used by the
backend.
This parameter is ignored when @option{-funit-at-a-time} is not used.
The default value is 3000.
@item large-function-growth
Specifies maximal growth of large function caused by inlining in percents.
This parameter is ignored when @option{-funit-at-a-time} is not used.
The default value is 200.
The default value is 100 which limits large function growth to 2.0 times
the original size.
@item inline-unit-growth
Specifies maximal overall growth of the compilation unit caused by inlining.
This parameter is ignored when @option{-funit-at-a-time} is not used.
The default value is 150.
The default value is 50 which limits unit growth to 1.5 times the original
size.
