Interprocedural Optimization (IPO) Quick Reference

-ipo

or

-ipoN

/Qipo

or

/QipoN

Enables interprocedural optimization for multi-file compilations.

Normally, multi-file compilations result in a single object file only. Passing an integer value for N allows you to specify number of mock object files to generate. (See IPO for Large Programs; the default value is 0.)

For more information, see the following topic:

• -ipo compiler option

-ipo-separate

/Qipo-separate

Instructs the compiler to generate a separate, real object file for each mock object file. Using this option overrides any integer value passed for ipoN. (See IPO for Large Programs for specifics.)

For more information, see the following topic:

• -ipo-separate compiler option

-ip

/Qip

Enables interprocedural optimizations for single file compilations. Instructs the compiler to generate a separate, real object file for each source file.

For more information, see the following topic:

• -ip compiler option

-finline-functions

No equivalent

Enables specific interprocedural optimizations for single file compilation. Can be used with use the -finline-limit option to limit the expansion size for inlined functions.
