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