Detailed Description

Structure describing the result of decoding an option.

Field Documentation

const char* cl_decoded_option::arg

The string argument, or NULL if none. For OPT_SPECIAL_* cases, the option or non-option command-line argument.

Referenced by display_help(), generate_option(), handle_option(), read_cmdline_options(), and set_option_handlers().

const char* cl_decoded_option::canonical_option[4]

The canonical form of the option and its argument, for when it is necessary to reconstruct argv elements (in particular, for processing specs and passing options to subprocesses from the driver).

Referenced by generate_canonical_option(), and handle_option().

size_t cl_decoded_option::canonical_option_num_elements

The number of elements in the canonical form of the option and arguments; always at least 1.

Referenced by generate_canonical_option(), and handle_option().

int cl_decoded_option::errors

Any flags describing errors detected in this option.

Referenced by generate_option(), and handle_option().

size_t cl_decoded_option::opt_index

The index of this option, or an OPT_SPECIAL_* value for non-options and unknown options.

Referenced by cancel_option(), display_help(), generate_option(), handle_option(), and merge_and_complain().

const char* cl_decoded_option::orig_option_with_args_text

The original text of option plus arguments, with separate argv elements concatenated into one string with spaces separating them. This is for such uses as diagnostics and -frecord-gcc-switches.

Referenced by generate_option(), handle_option(), and merge_and_complain().

int cl_decoded_option::value

For a boolean option, 1 for the true case and 0 for the "no-" case. For an unsigned integer option, the value of the argument. 1 in all other cases.

Referenced by display_help(), and handle_option().

const char* cl_decoded_option::warn_message

Any warning to give for use of this option, or NULL if none.

Referenced by generate_option(), and handle_option().
