@PROCESS
None.
Purpose
Previews the compilation steps specified on the command line, without actually invoking any compiler components.
At the points where the compiler executes commands to perform different compilation steps, this option displays a simulation of the commands it would run and the system argument lists it would pass, but it does not actually perform these actions.
Defaults
Not applicable.
Usage
- What files are involved
- What options are in effect for each step
It avoids the overhead of compiling the source code and avoids overwriting any existing files, such as .lst files. (If you are familiar with the make command, it is similar to make -n.)
This option produces the same output as -v and -V, but does not perform the compilation.
Note that if you specify this option with -qipa, the compiler does not display linker information subsequent to the IPA link step. This is because the compiler does not actually call IPA.
