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

Syntax

Linux and macOS:

-inline-max-size=n

-no-inline-max-size

Windows:

/Qinline-max-size=n

/Qinline-max-size-

Arguments

n

Is a positive integer that specifies the minimum size of what the inliner considers to be a large routine.

Default

-inline-max-size
or /Qinline-max-size

The compiler sets the maximum size (n) dynamically, based on the platform.

Description

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 macOS*) 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 option [q or Q]opt-report.

CAUTION

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.
