  20 /* List of all known ARC hardware modifier options (i.e., compiler
  21    options that are selecting a hardware facility).  There can be two
  22    types options: simple switches (e.g. code-density option can be
  23    on/off), or can accept multiple values (e.g., fpu options).
  24
  25    For any valid HW option, define a macro:
  26
  27    ARC_OPT (NAME, CODE, MASK, DOC)
  28
  29    where:
  30    NAME   Name (identifier) of a particular hardware modifier option,
  31           as in enum cpu_flags.
  32
  33    CODE   64-bit mask used to encode NAME.
  34
  35    MASK   Corresponding GCC's MASK_<option> macro.
  36
  37    DOC    A string used when emitting compiler errors or warnings.
  38
  39    For a multi-value option, define a macro for a valid value:
  40
  41    ARC_OPTX (NAME, CODE, VAR, VAL, DOC)
  42
  43    where:
  44    NAME   Name (identifier) of a particular hardware modifier
  45           configuration.
  46
  47    CODE   64-bit mask used to encode NAME.  It will be encoded in the
  48           same variable like options given via ARC_OPT.
  49
  50    VAR    Corresponding GCC's option variable.
  51
  52    VAL    Value to be set in VAR.
  53
  54    DOC    A string used when emitting compiler errors or warnings.
  55
  56    All multi-value options are defined using ARC_OPTX and ARC_OPT.
  57    ARC_OPT contains a mask with all valid values for the given
  58    option.  */
