The call graph generator takes a set of Fortran source files and produces a call graph with optional index and called-by tables. C files and fpp-processed files are not handled.
The call graph generator understands the following compiler options with the same meaning: -132, -dcfuns, -double, -dryrun, -dusty, -encoding, -english, -f2003, -f2008, -f95, -fixed, -free, -help, -I, -i8, -indirect, -info, -kind, -max_parameter_size, -maxcontin, -mismatch, -mismatch_all, -nihongo, -nocheck_modtime, -nomod, -noqueue, -o, -openmp, -Qpath, -r8, -strict95, -thread_safe, -u, -u=sharing, -v, -V, -w and -xlicinfo.
The “@filename” syntax may also be used, with the same effect as the “-indirect filename” option.
The call graph is written to the file specified by the -o option, or to standard output if no -o option is specified.
The following additional options control the output produced.
ENTRY
point names in the call graph; without this option, calls to
an ENTRY
point are shown as calls to the containing subprogram.
USE
statement, show the renaming.
