FF7777 is the UNIX Fortran 77 compiler. It accepts several types of argu-
ments:
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' sub-
stituted for `.f'.
Arguments whose names end with `.F' are also taken to be Fortran 77
source programs; these are first processed by the C preprocessor before
being compiled by ff7777.
Arguments whose names end with `.r' or `.e' are taken to be Ratfor or EFL
source programs respectively; these are first transformed by the ap-
propriate preprocessor, then compiled by ff7777.
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.
--cc Suppress loading and produce `.o' files for each source file.
--gg Produce additional symbol table information for dbx(1) and pass
the --llgg flag to ld(1) so that on abnormal terminations, the
memory image is written to file _c_o_r_e. Incompatible with --OO.
--oo _o_u_t_p_u_t
Name the final output file _o_u_t_p_u_t instead of `_a._o_u_t'.
--pp Prepare object files for profiling, see prof(1).
--ppgg Causes the compiler to produce counting code in the manner of
--pp, but invokes a run-time recording mechanism that keeps more
extensive statistics and produces a _g_m_o_n._o_u_t file at normal
termination. An execution profile can then be generated by use
of gprof(1).
--ww Suppress all warning messages. If the option is `-w66', only
Fortran 66 compatibility warnings are suppressed.
--DD_n_a_m_e =_d_e_f
--DD_n_a_m_e Define the _n_a_m_e to the C preprocessor, as if by `#define'. If
no definition is given, the name is defined as "1". (`.F' suf-
fix files only).
--II_d_i_r `#include' files whose names do not begin with `/' are always
sought first in the directory of the _f_i_l_e argument, then in
directories named in --II options, then in directories on a stan-
dard list. (`.F' suffix files only).
--OO Invoke an object-code optimizer. Incompatible with --gg.
--SS Compile the named programs, and leave the assembler-language
output on corresponding files suffixed `.s'. (No `.o' is
created.).
The following options are peculiar to ff7777.
--dd Used for debugging the compiler.
--ii22 On machines which support short integers, make the default in-
teger constants and variables short. --ii44 is the standard value
of this option). All logical quantities will be short.
--qq Suppress printing of file names and program unit names during
compilation.
--mm Apply the M4 preprocessor to each `.r' file before transforming
it with the Ratfor or EFL preprocessor.
--oonneettrriipp
--11 Compile DO loops that are performed at least once if reached.
(Fortran 77 DO loops are not performed at all if the upper lim-
it is smaller than the lower limit.)
--rr88 Treat all floating point variables, constants, functions and
intrinsics as double precision and all complex quantities as
double complex.
--uu Make the default type of a variable `undefined' rather than us-
ing the default Fortran rules.
--vv Print the version number of the compiler, and the name of each
pass as it executes.
--CC Compile code to check that subscripts are within declared array
bounds. For multi-dimensional arrays, only the equivalent
linear subscript is checked.
--FF Apply the C preprocessor to `.F' files, and the EFL, or Ratfor
preprocessors to `.e' and `.r' files, put the result in the
file with the suffix changed to `.f', but do not compile.
--EE_x Use the string _x as an EFL option in processing `.e' files.
--RR_x Use the string _x as a Ratfor option in processing `.r' files.
--NN[qqxxssccnn]_n_n_n
Make static tables in the compiler bigger. The compiler will
complain if it overflows its tables and suggest you apply one
or more of these flags. These flags have the following
meanings:
rr qq Maximum number of equivalenced variables. Default is 150.
xx Maximum number of external names (common block names,
subroutine and function names). Default is 200.
ss Maximum number of statement numbers. Default is 401.
cc Maximum depth of nesting for control statements (e.g. DO
loops). Default is 20.
_n Maximum number of identifiers. Default is 1009.
--UU Do not convert upper case letters to lower case. The default is
to convert Fortran programs to lower case except within charac-
ter string constants.
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._o_u_t'.
Programs compiled with ff7777 produce memory dumps in file _c_o_r_e upon abnor-
mal termination if the `--' flag was specified during loading. If the
environment variable f77_dump_flag is set to a value beginning with `_y'
or `_n', dumps for abnormal terminations are respectively forced or
suppressed.
