NAME

       GAC - The GAP Compiler

SYNOPSIS

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

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').

       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>.

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

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

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

       -fno-check-types
	      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.
