Command-line options for optimization
8.1
-inline
Specifies inline options. Default settings are smart, noauto.
Syntax
-inline keyword
The options for keyword are:
off | none
Turns off inlining.
on | smart
Turns on inlining for functions declared with the inline qualifier. This is the default.
auto
Attempts to inline small functions even if they are declared with inline.
noauto

deferred
Refrains from inlining until a file has been translated. This allows inlining of functions in both
directions.

Inlines functions up to n levels deep. Level 0 is the same as -inline on. For n, enter 1 to
8 levels. This argument is case-sensitive.
