/* 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. */
