.SH "DESCRIPTION"
.PP
GAC compiles GAP input files, which must be GAP source code (suffix '.g' or
\'.gap'), C source code (suffix '.c'), or compiled code files (suffix '.o').
.SH "OPTIONS"
If neither \fI\-c\fP nor \fI\-C\fP is given, then gac compiles the code
completely, producing a new kernel for static compilation or a dynamically
loadable '.so' file for dynamic compilation.
.TP
\fB\-d\fP, \fB\-\-dynamic\fP
Compile for dynamic loading.
.TP
\fB\-c\fP, \fB\-\-compile\fP
Only compile the input files to '.o' object files, which must be further
linked to make a static kernel or dynamically loadable module.
.TP
\fB\-C\fP, \fB\-\-create\-c\fP
Only compile the input files to C code, which will require compilation and
linking to be usable.
.TP
\fB\-r\fP
Statically compiled files are 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\fP, \fB\-\-output\fP \fI<output>\fP
Set the name of the output file.
.TP
\fB\-ffast\-int\-arith\fP
Emit code for arithmetic operations which works faster if both operands are
small integers, and slower otherwise.
.TP
\fB\-ffast\-plain\-lists\fP
Emit code for list access which works faster if the list is a plain list, and
slower otherwise.
.TP
\fB\-ffast\-list\-funcs\fP
Inline the list functions 'Add' and 'Length', for a small speed boost.
.TP
\fB\-fno\-check\-types\fP
Emit no error checks for element types, which improves performance but may
result in a crash if an error happens.
.TP
\fB\-fno\-check\-list\-elms\fP
Emit no error checks for list access, which improves performance but may
result in a crash if an error happens.
.TP
\fB\-p\fP \fI<option>\fP
Pass the given option to the C compiler.
.TP
\fB\-P\fP \fI<option>\fP
Pass the given option to the C linker.
.TP
\fB\-k\fP, \fB\-\-gap\-compiler\fP \fI<path>\fP
Use the given path to find the GAP binary, instead of the default.
.TP
\fB\-i\fP, \fB\-\-gap\-include\fP \fI<path>\fP
Use the given path to find the GAP header files, instead of the default.
.TP
\fB\-l\fP, \fB\-\-gap\-binary\fP \fI<path>\fP
Use the given path to find the GAP binary directory, instead of the default.
