@ -212,12 +212,12 @@ Whether identical functions should be merged into one function.
Default: yes.
* `-fsubroutine-extraction`, `-fno-subroutine-extraction` –
Whether identical fragments of functions should be extracted into subroutines.
Whether identical fragments of functions should be extracted into subroutines (experimental).
Makes the code smaller. Computationally very expensive.
`.ini` equivalent: `subroutine_extraction`.
Default: no.
* `-Os`, `--size` – Optimize for size, sacrificing some speed (experimental).
Also enables `-fsubroutine-extraction`.
* `-Of`, `--fast` – Optimize for speed, even if it increases the size a bit (experimental).
Also enables `-finline`.
