22 * DESCRIPTION
23 *
24 * all options for gcc start with '-' and are for the most part
25 * single options (no parameters as separate argument).
26 * There are of course exceptions to this rule, so here is an
27 * exhaustive list of options that do take parameters (potentially)
28 * as a separate argument:
29 *
30 * Compiler:
31 * -x language
32 * -o filename
33 * -aux-info filename
34 *
35 * Preprocessor:
36 * -D name
37 * -U name
38 * -I dir
39 * -MF file
40 * -MT target
41 * -MQ target
42 * (all -i.* arg)
43 * -include file
44 * -imacros file
45 * -idirafter dir
46 * -iwithprefix dir
47 * -iwithprefixbefore dir
48 * -isystem dir
49 * -A predicate=answer
50 *
51 * Linking:
52 * -l library
53 * -Xlinker option
54 * -u symbol
55 *
56 * Misc:
57 * -b machine
58 * -V version
59 * -G num (see NOTES below)
60 *
61 * NOTES
62 * There is -G option for compatibility with System V that
63 * takes no parameters. This makes "-G num" parsing ambiguous.
64 * This option is synonymous to -shared, and as such we will
65 * not support it for now.
66 *
67 * Special interest options
68 *
69 * Assembler Option
70 * -Wa,option
71 *
72 * Linker Options
73 * object-file-name -llibrary -nostartfiles -nodefaultlibs
74 * -nostdlib -s -static -static-libgcc -shared -shared-libgcc
75 * -symbolic -Wl,option -Xlinker option -u symbol --image-base
76 *
77 * Directory Options
78 * -Bprefix -Idir -I- -Ldir -specs=file
79 *
80 * Target Options
81 * -b machine -V version
82 *
83 * Please note that the Target Options are relevant to everything:
84 * compiler, linker, assembler, preprocessor.
85 *
