/* List of all known ARC hardware modifier options (i.e., compiler
   options that are selecting a hardware facility).  There can be two
   types options: simple switches (e.g. code-density option can be
   on/off), or can accept multiple values (e.g., fpu options).

   For any valid HW option, define a macro:

   ARC_OPT (NAME, CODE, MASK, DOC)

   where:
   NAME	  Name (identifier) of a particular hardware modifier option,
	  as in enum cpu_flags.

   CODE	  64-bit mask used to encode NAME.

   MASK	  Corresponding GCC's MASK_<option> macro.

   DOC	  A string used when emitting compiler errors or warnings.

   For a multi-value option, define a macro for a valid value:

   ARC_OPTX (NAME, CODE, VAR, VAL, DOC)

   where:
   NAME	  Name (identifier) of a particular hardware modifier
	  configuration.

   CODE	  64-bit mask used to encode NAME.  It will be encoded in the
	  same variable like options given via ARC_OPT.

   VAR	  Corresponding GCC's option variable.

   VAL	  Value to be set in VAR.

   DOC	  A string used when emitting compiler errors or warnings.

   All multi-value options are defined using ARC_OPTX and ARC_OPT.
   ARC_OPT contains a mask with all valid values for the given
   option.  */
