XL Fortran Enterprise Edition for AIX : User's Guide - IBM

-# Option
Syntax
-#
Generates information on the progress of the compilation without actually running
the individual components.
Rules
At the points where the compiler executes commands to perform different
compilation steps, this option displays a simulation of the system calls it would do
and the system argument lists it would pass, but it does not actually perform these
actions.
Examining the output of this option can help you quickly and safely determine the
following information for a particular compilation:
v What files are involved
v 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. (For those who are familiar with the make
command, it is similar to make -n.)
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.
Related Information
The “-v Option” on page 273 and “-V Option” on page 274 produce the same
output but also performs the compilation.
