Specifies the lower limit for the size of what the inliner considers to be a large routine.
Linux and macOS:
- Is a positive integer that specifies the minimum size of what the inliner considers to be a large routine.
- The compiler sets the maximum size (n) dynamically, based on the platform.
This option specifies the lower limit for the size of what the inliner considers to be a large routine (
a function). The inliner classifies routines as small, medium, or large. This option specifies the boundary between what the inliner considers to be medium and large-size routines.
The inliner prefers to inline small routines. It has a preference against inlining large routines. So, any large routine is highly unlikely to be inlined.
If you specify
/Qinline-max-size-(Windows*), there are no large routines. Every routine is either a small or medium routine.
To see compiler values for important inlining limits, specify option
[q or Q]opt-report.
When you use this option to increase the default limit, the compiler may do so much additional inlining that it runs out of memory and terminates with an "out of memory" message.
