‑‑[no_]autoinline

2.1.7. ‑‑[no_]autoinline

This option enables or disables automatic inlining of functions.

The compiler automatically inlines functions where it is sensible to do so. The ‑Ospace and ‑Otime options, together with some other factors such as function size, influence how the compiler automatically inlines functions.

Selecting ‑Otime, in combination with various other factors, increases the likelihood that functions are inlined.

Default

For optimization levels ‑O0 and ‑O1, the default is --no_autoinline.

For optimization levels ‑O2 and ‑O3, the default is ‑‑autoinline.
