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:
47 * -iwithprefixbefore dir
59 * -G num (see NOTES below)
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.
67 * Special interest 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
78 * -Bprefix -Idir -I- -Ldir -specs=file
81 * -b machine -V version
83 * Please note that the Target Options are relevant to everything:
84 * compiler, linker, assembler, preprocessor.
