Specifies the lower limit for the size of what the inliner considers to be a large routine.

Is a positive integer that specifies the minimum size of what the inliner considers to be a large routine. |
-no-inline-max-size |
The compiler uses default heuristics for inline routine expansion. |
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 -no-inline-max-size (Linux and Mac OS X) or /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 compiler option -opt-report (Linux and Mac OS X) or /Qopt-report (Windows).
To see compiler values for important inlining limits, specify compiler option -opt-report (Linux and Mac OS X) or /Qopt-report (Windows).
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.
