6 gac - Compile GAP input files
7
9 gac [-d] [-c|-C] [-o <output>] {-f<option>} <input> ...
10
12 GAC compiles GAP input files, which must be GAP source code (suffix
13 '.g' or ´.gap'), C source code (suffix '.c'), or compiled code files
14 (suffix '.o').
15
17 If neither -c nor -C is given, then gac compiles the code completely,
18 producing a new kernel for static compilation or a dynamically loadable
19 '.so' file for dynamic compilation.
20
21 -d, --dynamic
22 Compile for dynamic loading.
23
24 -c, --compile
25 Only compile the input files to '.o' object files, which must be
26 further linked to make a static kernel or dynamically loadable
27 module.
28
29 -C, --create-c
30 Only compile the input files to C code, which will require com‐
31 pilation and linking to be usable.
32
33 -r Statically compiled files are assumed to be given by pathnames
34 relative to the GAP root, and will be compiled for automatic
35 loading when files are sought relative to the GAP root.
36
37 -o, --output <output>
38 Set the name of the output file.
39
40 -ffast-int-arith
41 Emit code for arithmetic operations which works faster if both
42 operands are small integers, and slower otherwise.
43
44 -ffast-plain-lists
45 Emit code for list access which works faster if the list is a
46 plain list, and slower otherwise.
47
48 -ffast-list-funcs
49 Inline the list functions 'Add' and 'Length', for a small speed
50 boost.
51
52 -fno-check-types
53 Emit no error checks for element types, which improves perfor‐
54 mance but may result in a crash if an error happens.
55
56 -fno-check-list-elms
57 Emit no error checks for list access, which improves performance
58 but may result in a crash if an error happens.
59
60 -p <option>
61 Pass the given option to the C compiler.
62
63 -P <option>
64 Pass the given option to the C linker.
65
66 -k, --gap-compiler <path>
67 Use the given path to find the GAP binary, instead of the
68 default.
69
70 -i, --gap-include <path>
71 Use the given path to find the GAP header files, instead of the
72 default.
73
74 -l, --gap-binary <path>
75 Use the given path to find the GAP binary directory, instead of
76 the default.
