| OFF | The compiler does not generate a multifile assembly file. |
This option tells the compiler to optimize across multiple files and generate a single assembly file (named ipo_out.s on Linux and Mac OS systems; ipo_out.asm on Windows systems).
It performs the same optimizations as -ipo (Linux and Mac OS) or /Qipo (Windows), but compilation stops before the final link stage, leaving an optimized assembly file that can be used in further link steps.
