inline-forceinline, Qinline-forceinline

Instructs the compiler to force inlining of functions suggested for inlining whenever the compiler is capable doing so.

Syntax

Linux and macOS:
-inline-forceinline
Windows:
/Qinline-forceinline
Default
OFF
The compiler uses default heuristics for inline routine expansion.
Description
This option instructs the compiler to force inlining of functions suggested for inlining whenever the compiler is capable doing so.
Without this option, the compiler treats functions declared with the inline keyword as merely being recommended for inlining. When this option is used, it is as if they were declared with the keyword __forceinline keyword.
Because C++ member functions whose definitions are included in the class declaration are considered inline functions by default, using this option will also make these member functions "forceinline" functions.
To see compiler values for important inlining limits, specify option
[q or Q]opt-report
.
When you use this option to change the meaning of inline to "forceinline", the compiler may do so much additional inlining that it runs out of memory and terminates with an "out of memory" message.
Alternate Options
None
