| -ipo-jobs[n] |
Specifies the number of commands (jobs) to be executed simultaneously during the link phase of Interprocedural Optimization (IPO). The default is 1 job |
| -finline-functions -finline-level=2 |
This option enables function inlining within the current source file at the compiler's discretion. This option is enabled by default at -O2 and -O3. |
| -finline-factor=n |
This option scales the total and maximum sizes of functions that can be inlined. The default value of n is 100, i.e., 100% or a scale factor of one |
