omf77 is a program to compile OpenMP programs written in Fortran77.
omf77 processes input files through one or more of with stages:
compilation, assembly, and linking, with preprocessing as a option.
This compiler is a kind of "f2c" (Fortran to C) program, which use the
native C compiler as the backend.
This man page contains descriptions for only omf77-specific
aspects of the compiler, though it also contains summaries
of some general-purpose options.
omf77 is a translator which translate Fortran 77 program
into a C program. For a fuller explanation
of the compile options, see options of the backend C compiler which
is specified in the installation. Fortran source files use the suffix
'.f' or '.F': Fortran 77 programs to be preprocessed by cpp use
the suffix '.F'.
Display Omni version.
Specify a name of configuration, listed below (Omni configuration and
platform dependent) as examples:
If not specified, default configuration (depend on Omni configuration
and platform) is used.
Specify a command name of backend C compiler. If not specified,
default C compiler (depend on Omni configuration and platform) is used.
Compile or assemble the source files, but do not
link. The compiler output is an object file corresponding to each
Define macro macro with the string `1' as its definition.
Define macro macro as defn.
Produce debugging information.
Append directory dir to the list of directories
searched for include files.
Add directory dir to the list of directories to be searched for `-l'.
Use the library named library when linking.
Place output in file.
Stop after the stage of compilation proper; do not assemble.
The output is an assembler code file for each non-assembler input file specified.
Undefine macro macro.
Stop after parsing leaving the intermediate file.
Stop before calling the backend compiler. Leave the intermediate
C file after OpenMP transformation.
INTEGER (integer type declaration without size and implicitly
declared integer type) will be treated
as INTEGER*#. '#' must be one of 2, 4, and 8. The default is 4. 8 is
avairable only when a backend C compiler supports 64 bit integer.
REAL (single precision real type and implicitly declared real type) will be treated
as REAL*#. '#' must be 4 or 8. The default is 4.
DOUBLE PRECISION (double precision real type) will be treated
as REAL*#. '#' must be 4 or 8. The default is 8.
(If configured with '--enable-mreal') Specify a precision of
MULTIPLE PRECISION and/or REAL*16 type with '#' in bits. If '#' is
less than 52, it will be raised to 52.
Treat variables decalared implicitly as error.
Generate floating point exception checking code.
Generate floating point exception checking code and dumping core when the exception occur.
Not allow to be equivalent character variables to other types by
Not allow to initialize non-character variables with characters
by DATA statement.
Not allow non-standard initialization in common block.
Imply all other -pedantic* options.
If alignment of double is NOT sizeof double, treat alignment of double is sizeof double.
Disable complex and quad/multiple precision real (If configured
with '--enable-mreal') constant folding for (slight) precision improvement.
(If configured with '--enable-mreal') Disable quad/multiple
precision real specific optimization.
If set (as any value) at execution of a program generated by
omf77, I/O runtime routines swap the byte oredr of data for direct
access I/O mode.
In addition to OpenMP standard environment variables
Omni environment variables controls the parallel execution.
