Arguments whose names end with `.f' are taken to be Fortran 77 source programs; they are compiled, and each object program is left on the file in the current directory whose name is that of the source with `.o' substituted for '.f'.
Arguments whose names end with `.r' or `.e' are taken to be Ratfor or EFL source programs, respectively; these are first transformed by the appropriate preprocessor, then compiled by f77.
In the same way, arguments whose names end with `.c' or `.s' are taken to be C or assembly source programs and are compiled or assembled, producing a `.o' file.
The following options have the same meaning as in cc (1). See ld (1) for load-time options.
-c Suppress loading and produce `.o' files for each source file.
-p Prepare object files for profiling, see prof (1).
-O Invoke an object-code optimizer.
-S Compile the named programs, and leave the assembler-language output on corresponding files suffixed `.s'. (No `.o' is created.).
-f Use a floating point interpreter (for PDP11's that lack 11/70-style floating point).
-o " output" Name the final output file output instead of `a.out'.
The following options are peculiar to f77 .
-onetrip Compile DO loops that are performed at least once if reached. (Fortran 77 DO loops are not performed at all if the upper limit is smaller than the lower limit.)
-u Make the default type of a variable `undefined' rather than using the default Fortran rules.
-q Suppress printing of procedure names during compilation.
-C Compile code to check that subscripts are within declared array bounds.
-w Suppress all warning messages. If the option is `-w66', only Fortran 66 compatibility warnings are suppressed.
-F Apply EFL and Ratfor preprocessor to relevant files, put the result in the file with the suffix changed to `.f', but do not compile.
-m Apply the M4 preprocessor to each `.r' or `.e' file before transforming it with the Ratfor or EFL preprocessor.
-E x Use the string x as an EFL option in processing `.e' files.
-R x Use the string x as a Ratfor option in processing `.r' files.
Other arguments are taken to be either loader option arguments, or F77-compatible object programs, typically produced by an earlier run, or perhaps libraries of F77-compatible routines. These programs, together with the results of any compilations specified, are loaded (in the order given) to produce an executable program with name `a.out'.
