GAC - The GAP Compiler


gac [-c|-d] [-o <output>] {-f<option>} <input>...


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').

If neither -c nor -d is given, then 'gac' produces
a new kernel, which contains the compiled code for all the input files.

-c Compiles the input files to statically loadable object files, which must be linked
together to a new kernel.

-d Compiles the input files to dynamically loadable object files, which can be loaded
by a kernel at runtime.

-C Only compiles the input files to C code, which will require compilation and linking
to be usable.

-r 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.

-o <output>
Name the output file <output>.

Emit code for arithmetic operations, which works faster if both operands are
small integers and slower otherwise.

Emit code for list access, which works faster if the list is a plain list and
slower otherwise.

Inline the functions 'Add' and 'Length' the code, which makes it a bit faster.

Emit no error checks for list access, which makes it faster but may dump core if
an error happens.

-p <option>
Pass the option <option> to the C compiler.

-P <option>
Pass the option <option> to the C linker.
