Tells the compiler to optimize across multiple files and generate a single assembly file.
Linux and macOS:
- 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
systems; ipo_out.asm on Windows* systems).
It performs the same optimizations as the
[Q]ipooption, but compilation stops before the final link stage, leaving an optimized assembly file that can be used in further link steps.
