--- Comment #12 from Ben Barrowes <barrowes at alum dot mit.edu> --- I use these intermediate files during the software analysis process, but then delete them later. They are useful for me to have. When I am given a makefile, it is often 1000's loc. I am not sure I want to go in and modify it such as you suggest below and tell the customer it is for their own good. I'd rather be able to set a couple of switches to the preprocessor and get what I want. gfortran already allows to create a *.d file in each directory for each file. Is that poor software design as well? And when gfortran files are preprocessed all into a *.f90 file, except when they are not (see Thomas's email below), is that poor software design? ifort allows for the creation of these intermediate preprocessed files, creating *.i and *.i90 files. IBM XL allows this as well using the -d switch: https://www.ibm.com/docs/en/xl-fortran-aix/16.1.0?topic=preprocessor-passing-fortran-files-through-c And the intermediate filename becomes Ffilename.f* Can gfortran be modified to have the option to do this as well?
