.SH DESCRIPTION
|
|
.LP
|
|
.I afpc
|
|
is a fast
|
|
.B Pascal
|
|
compiler. It translates
|
|
.B Pascal
|
|
programs
|
|
into ack(1)-compatible relocatable object modules, and does so in one pass.
|
|
Then, if the \fB\-c\fP flag is not given,
|
|
.I afpc
|
|
offers the object modules to a link-editor,
|
|
to create an executable binary.
|
|
.LP
|
|
.I Fpc
|
|
accepts several types of filename arguments. Files with
|
|
names ending in
|
|
.B .p
|
|
are taken to be
|
|
.B Pascal
|
|
source programs.
|
|
They are compiled, and the resulting object module is placed in the current
|
|
directory.
|
|
The object module is named after its source file, the suffix
|
|
.B .o
|
|
replacing
|
|
.BR .p
|
|
in the name of the object.
|
|
A file with suffix
|
|
.B .p
|
|
is passed through the C preprocessor if it begins with a '#'.
|
|
.LP
|
|
Other arguments refer to loader options,
|
|
object modules, or object libraries.
|
|
Unless the
|
|
.B \-c
|
|
flag is given, these modules and libraries, together with the results of any
|
|
specified compilations, are passed (in the order given) to the
|
|
link-editor to produce
|
|
an output file named
|
|
.IR a.out .
|
|
You can specify a name for the executable by using the
|
|
.B \-o
|
|
option.
|
|
.LP
|
|
If a single
|
|
.B Pascal
|
|
program is compiled and loaded all at once, the object module
|
|
file is deleted.
|
|
.SH OPTIONS
|
|
.LP
|
|
.IP \fB\-c\fP
|
|
.br
|
|
Suppress the loading phase of the compilation, and force an object module to
|
|
be produced, even if only one program is compiled.
|
|
A single object module can be named explicitly using the
|
|
.B \-o
|
|
option.
|
|
.IP \fB\-D\fIname\fR\fB=\fIdef\fR
|
|
Define a symbol
|
|
.I name
|
|
to the
|
|
preprocessor, as if by "#define".
|
|
.IP \fB\-D\fIname\fR
|
|
.br
|
|
same as \fB\-D\fIname\fB=1\fR.
|
|
.IP \fB\-I\fIpathname\fR
|
|
.br
|
|
Add
|
|
.I pathname
|
|
to the list of directories in which to search for
|
|
.B #include
|
|
files with filenames not beginning with slash.
|
|
The preprocessor first searches for
|
|
.B #include
|
|
files in the directory containing
|
|
.I sourcefile,
|
|
then in directories in
|
|
.B \-I
|
|
options, and finally, in
|
|
.I /usr/include.
|
|
.IP "\fB\-o \fIoutput\fR"
|
|
Name the final output file
|
|
.I output.
|
|
.IP \fB\-U\fIname\fR
|
|
.br
|
|
Remove any initial definition of
|
|
.I name.
|
|
.IP \fB\-v\fP
|
|
.br
|
|
Verbose. Print the commands as they are executed.
|
|
.IP \fB\-vn\fP
|
|
.br
|
|
Verbose, no execute. Only print the commands, do not execute them.
|
|
.IP \fB\-L\fP
|
|
.br
|
|
do not generate code to keep track of
|
|
the current location in the source code.
|
|
.IP \fB\-w\fP
|
|
.br
|
|
suppress warning messages.
|
|
.IP \fB\-d\fP
|
|
.br
|
|
allow for "long"s.
|
|
.IP \fB\-i\fInum\fR
|
|
.br
|
|
set size for integer sets. By default, the set size is the word size.
|
|
.IP \fB\-C\fP
|
|
.br
|
|
distinguish between lower case and upper case. Normally, upper case letters
|
|
are considered equal to their lower case counterpart.
|
|
.IP \fB\-t\fP
|
|
.br
|
|
trace calls and exits of procedures and functions.
|
|
.IP \fB\-R\fP
|
|
.br
|
|
disable all range-checks.
|
|
.IP \fB\-A\fP
|
|
.br
|
|
enable extra array bound checks. Unfortunately, the back-end used for this
|
|
compiler is a bit sloppy, so extra array bound checks are needed if you want
|
|
detection of array bound errors.
|
|
.IP \fB\-a\fP
|
|
.br
|
|
disable assertions. Assertions are skipped instead of evaluated.
|
|
.IP "\fB\-U+\fP, \fB\-u+\fP"
|
|
.br
|
|
allow for underscores within identifiers. Identifiers may not start
|
|
with an underscore, even if this flag is given.
|
|
.IP \fB-s+\fP
|
|
.br
|
|
allow only standard
|
|
.BR Pascal .
|
|
This disables the \fB\-c+\fP, \fB\-d\fR, \fB\-u+\fR,
|
|
\fB\-U+\fR and \fB\-C\fR options.
|
|
Furthermore, assertions are not recognized at all.
|
|
.IP \fB-c+\fP
|
|
.br
|
|
allow C-like strings. This option is mainly intended for usage with
|
|
C-functions. This option will cause the type 'string' to be known.
|
|
.IP \fB\-M\fIcompiler\fR
|
|
.br
|
|
use \fIcompiler\fR as Modula-2 compiler instead of the default.
