# inline-min-size, Qinline-min-size

Specifies the upper limit for the size of what the inliner considers to be a small routine.

## Syntax

Linux: | -inline-min-size=n -no-inline-min-size

macOS: | -inline-min-size=n -no-inline-min-size

Windows: | /Qinline-min-size=n /Qinline-min-size-

## Arguments

n | Is a positive integer that specifies the maximum size of what the inliner considers to be a small routine.

## Default

-no-inline-min-size or /Qinline-min-size- | The compiler uses default heuristics for inline routine expansion.

## Description

This option specifies the upper limit for the size of what the inliner considers to be a small routine (a function). The inliner classifies routines as small, medium, or large. This option specifies the boundary between what the inliner considers to be small and medium-size routines.

The inliner has a preference to inline small routines. So, when a routine is smaller than or equal to the specified size, it is very likely to be inlined.

If you specify -no-inline-min-size (Linux* and macOS) or /Qinline-min-size- (Windows*), there is no limit to the size of small routines. Every routine is a small routine; there are no medium or large routines.

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.
