void add_params ( )

Add the N PARAMS to the current list of compiler parameters.

References memcpy(), num_compiler_params, and params_finished.

Referenced by global_init_params().

int default_param_value ( )

Return the default value of parameter NUM.

Referenced by default_options_optimization().

void finish_params ( void )

Note that all parameters have been added and all default values
   set.

References params_finished.

Referenced by general_init(), and main().

size_t get_num_compiler_params ( void )

Return the current value of num_compiler_params, for the benefit of
   plugins that use parameters as features.

References num_compiler_params.

Referenced by init_options_struct().

void global_init_params ( void )

Add all parameters and default values that can be set in both the
   driver and the compiler proper.

References add_params(), and LAST_PARAM.

Referenced by general_init(), and main().

void init_param_values ( )

Initialize an array PARAMS with default values of the
   parameters.

Referenced by init_options_struct().

void maybe_set_param_value	(	compiler_param	num,
		int	value,
		int *	params,
		int *	params_set
	)

Set the value of the parameter given by NUM to VALUE in PARAMS and
   PARAMS_SET, implicitly, if it has not been set explicitly by the
   user.

References set_param_value_internal().

Referenced by default_options_optimization(), and finish_options().

void set_default_param_value ( )

Set the default value of a parameter given by NUM to VALUE, before
   option processing.

References params_finished.

Referenced by init_ggc_heuristics().

void set_param_value	(	const char *	name,
		int	value,
		int *	params,
		int *	params_set
	)

Set the VALUE associated with the parameter given by NAME in PARAMS
   and PARAMS_SET.

Referenced by common_handle_option(), and handle_param().

static void set_param_value_internal	(	compiler_param	num,
		int	value,
		int *	params,
		int *	params_set,
		bool	explicit_p
	)

static

Set the value of the parameter given by NUM to VALUE in PARAMS and
   PARAMS_SET.  If EXPLICIT_P, this is being set by the user;
   otherwise it is being set implicitly by the compiler.
