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. */
