| * |
| * DESCRIPTION |
| * |
| * all options for gcc start with '-' and are for the most part |
| * single options (no parameters as separate argument). |
| * There are of course exceptions to this rule, so here is an |
| * exhaustive list of options that do take parameters (potentially) |
| * as a separate argument: |
| * |
| * Compiler: |
| * -x language |
| * -o filename |
| * -aux-info filename |
| * |
| * Preprocessor: |
| * -D name |
| * -U name |
| * -I dir |
| * -MF file |
| * -MT target |
| * -MQ target |
| * (all -i.* arg) |
| * -include file |
| * -imacros file |
| * -idirafter dir |
| * -iwithprefix dir |
| * -iwithprefixbefore dir |
| * -isystem dir |
| * -A predicate=answer |
| * |
| * Linking: |
| * -l library |
| * -Xlinker option |
| * -u symbol |
| * |
| * Misc: |
| * -b machine |
| * -V version |
| * -G num (see NOTES below) |
| * |
| * NOTES |
| * There is -G option for compatibility with System V that |
| * takes no parameters. This makes "-G num" parsing ambiguous. |
| * This option is synonymous to -shared, and as such we will |
| * not support it for now. |
| * |
| * Special interest options |
| * |
| * Assembler Option |
| * -Wa,option |
| * |
| * Linker Options |
| * object-file-name -llibrary -nostartfiles -nodefaultlibs |
| * -nostdlib -s -static -static-libgcc -shared -shared-libgcc |
| * -symbolic -Wl,option -Xlinker option -u symbol --image-base |
| * |
| * Directory Options |
| * -Bprefix -Idir -I- -Ldir -specs=file |
| * |
| * Target Options |
| * -b machine -V version |
| * |
| * Please note that the Target Options are relevant to everything: |
| * compiler, linker, assembler, preprocessor. |
