Tells the compiler to optimize across multiple files and generate a single assembly file. This feature is only available for ifort.

Syntax

Linux:

-ipo-S

macOS:

-ipo-S

Windows:

/Qipo-S

Arguments

None

Default

OFF

The compiler does not generate a multifile assembly file.

Description

This option tells the compiler to optimize across multiple files and generate a single assembly file (named ipo_out.s on Linux* and macOS systems; ipo_out.asm on Windows* systems).

It performs the same optimizations as the [Q]ipo option, but compilation stops before the final link stage, leaving an optimized assembly file that can be used in further link steps.

None

Alternate Options
