−/* 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.  */
