  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
  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  *
