It accepts several<br /> types of arguments:<br /> <br /> Arguments whose names end with `.f' are taken to be Fortran<br /> 77 source programs; they are compiled, and each object pro-<br /> gram is left on the file in the current directory whose name<br /> is that of the source with `.o' substituted for '.f'.<br /> <br /> Arguments whose names end with `.r' or `.e' are taken to be<br /> Ratfor or EFL source programs, respectively; these are first<br /> transformed by the appropriate preprocessor, then compiled<br /> by f77.<br /> <br /> In the same way, arguments whose names end with `.c' or `.s'<br /> are taken to be C or assembly source programs and are com-<br /> piled or assembled, producing a `.o' file.<br /> <br /> The following options have the same meaning as in _c_c(1).<br /> See _l_d(1) for load-time options.<br /> <br /> -c Suppress loading and produce `.o' files for each source<br /> file.<br /> <br /> -p Prepare object files for profiling, see _p_r_o_f(1).<br /> <br /> -O Invoke an object-code optimizer.<br /> <br /> -S Compile the named programs, and leave the assembler-<br /> language output on corresponding files suffixed `.s'.<br /> (No `.o' is created.).<br /> <br /> -f Use a floating point interpreter (for PDP11's that lack<br /> 11/70-style floating point).<br /> <br /> -o output<br /> Name the final output file _o_u_t_p_u_t instead of `a.out'.<br /> <br /> The following options are peculiar to _f_7_7.<br /> <br /> -onetrip<br /> Compile DO loops that are performed at least once if<br /> reached. (Fortran 77 DO loops are not performed at all<br /> if the upper limit is smaller than the lower limit.)<br /> <br /> -u Make the default type of a variable `undefined' rather<br /> than using the default Fortran rules.<br /> <br /> -C Compile code to check that subscripts are within<br /> declared array bounds.<br /> <br /> -w Suppress all warning messages. If the option is<br /> `-w66', only Fortran 66 compatibility warnings are<br /> suppressed.<br /> <br /> -F Apply EFL and Ratfor preprocessor to relevant files,<br /> put the result in the file with the suffix changed to<br /> `.f', but do not compile.<br /> <br /> -m Apply the M4 preprocessor to each `.r' or `.e' file<br /> before transforming it with the Ratfor or EFL prepro-<br /> cessor.<br /> <br /> -E_x Use the string _x as an EFL option in processing `.e'<br /> files.<br /> <br /> -R_x Use the string _x as a Ratfor option in processing `.r'<br /> files.<br /> <br /> Other arguments are taken to be either loader option argu-<br /> ments, or F77-compatible object programs, typically produced<br /> by an earlier run, or perhaps libraries of F77-compatible<br /> routines. These programs, together with the results of any<br /> compilations specified, are loaded (in the order given) to<br /> produce an executable program with name `a.out'.<br /> <br /> == FILES ==<br /> file.[fresc] input file<br /> file.o object file<br /> a.out loaded output<br /> /usr/lib/f77pass1 compiler<br /> /lib/f1 pass 2<br /> /lib/c2 optional optimizer<br /> /usr/lib/libF77.a intrinsic function library<br /> /usr/lib/libI77.a Fortran I/O library<br /> /lib/libc.a C library, see section 3<br /> <br /> == SEE ALSO ==<br /> S.
