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.
