.TH GAC "1" "March 2003" "The GAP team" "User Commands"
.SH NAME
GAC \- The GAP Compiler
.SH SYNOPSIS
.PP
gac [\fB-c\fR|\fB-d\fR] [\fB-o <output>\fR] {\fB-f<option>\fR} <input>...
.IP
.SH DESCRIPTION
GAC compiles the input files. Input files must be
GAP source code (suffix '.g' or '.gap'), C source code
(suffix '.c'), or compiled code files (suffix '.o').
.TP
If neither \fB-c\fR nor \fB-d\fR is given, then 'gac' produces
a new kernel, which contains the compiled code for all
the input files.
.TP
\fB-c\fR
Compiles the input files to statically loadable object files, which must be
linked together to a new kernel.
.TP
\fB-d\fR
Compiles the input files to dynamically loadable object files, which can be loaded by a kernel at runtime.
.TP
\fB-C\fR
Only compiles the input files to C code, which
will require compilation and linking to be usable.
.TP
\fB-r\fR
Statically compiled files will be assumed to be given by pathnames relative to
the GAP root, and will be compiled for automatic loading when files are sought
relative to the GAP root.
.TP
\fB-o <output>\fR
Name the output file <output>.
.TP
\fB-ffast-int-arith\fR
Emit code for arithmetic operations, which works faster if both operands are
small integers and slower otherwise.
.TP
\fB-ffast-plain-lists\fR
Emit code for list access, which works faster if the list is a plain
list and slower otherwise.
.TP
\fB-ffast-list-funcs\fR
Inline the functions 'Add' and 'Length' the code, which makes it a
bit faster.
.TP
\fB-fno-check-types\fR
Emit no error checks for list access, which makes it faster but
may dump core if an error happens.
.TP
\fB-p <option>\fR
Pass the option <option> to the C compiler.
.TP
\fB-P <option>\fR
Pass the option <option> to the C linker.
