simcomp - compile a Simula main program or separate
simcomp filename [-L=path] [-I=path] [-l] [-f] [-r] [-h]
[-list] [-e] [-w] [-x] [-z]
The normal action of the Simula compiler is to read the
input file and translate it into an object code file and an
attribute information file. This normal action can be
changed by the use of options.
All produced files have the same name as the input file, but
with different extensions. The object code file is given the
extension '.o'. The attribute information file is given
extension '.atr'. This file contains information used by the
debugger and for separate compilation.
If errors are detected, they are listed at the end of the
compilation. Errors are by default listed on standard error.
The filename can be givien with or without the extension
'.sim'. It must be present.
Options may appear in any order.
Colon separated list of directories of where to search
for libraries, specified by the -I= option. Search
order is: this environment variable is concatenated to
the content of the -L= option. Useful for a default
path to be used in a series of compilations.
Colon separated list of libraries of where to search
for Simula attribute files and include files. The full
pathname of the libraries are identified by searching
the directory searchlist defined by the -L= option and
the SIM_LIBRARY_PATH environment variable. The result
is the library searchpath with one element for each
item in the -I= parameter: '.', <dirn>/<lib1>,
-l Include a search of the libraries installed with the
Lund Simula system. Shorthand for
-f Report all files read during compilation. Useful to
sort out binding of dependencies on external files.
-r Specifies recompilation, the compilation is aborted if
the interface part of the attribute file would need to
-h Line numbers inhibited. Do not produce code to take
care of line numbers during run time. This option
should be used only in fully tested programs, since it
makes use of several of the debugger commands
impossible. The benefits resulting from use of the h
option are savings in object code size and in execution
-l ist Listing. Produce a list file with the same name as
the input file, but with extension '.lis' It contains
the source program text, line numbers and error
messages. file.lis will be produced, even if the
compiler was stopped by a fatal error.
-e Error listing. Produce an error list on file with
extension '.err'. This is really the same as
redirecting standard error. The error list normally
appearing on the terminal is written to the file with
extension '.err' instead.
-w Warning messages inhibited. Normally at most 64
warnings and errors will be produced, then the
compilation is aborted. With the w option all warnings
will be inhibited and not counted in the sum of errors
and warnings. Even when warning messages are inhibited
the number of warnings will be printed at the end of
-x Direct error messages. Error messages will be written
on the console as soon as the errors are detected. The
message will give less information than that at the end
of pass five. This option is mainly intended for
implementor use, but can be useful if the compiler for
some reason can not complete. See Appendix D for
matching error numbers with error messages.
-z Symbolic intermediate code. Produce symbolic
intermediate code on the file with extension '.zr'.
This option is mainly intended for implementor use.
