Typedef Documentation

typedef enum compiler_param compiler_param

The parameters in use by language-independent code.

typedef struct param_info param_info

The information associated with each parameter.

Enumeration Type Documentation

enum compiler_param

Enumerator:

LAST_PARAM

Function Documentation

void add_params	(	const param_info	params[],
		size_t	n
	)

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

int default_param_value ( compiler_param num )

Return the default value of parameter NUM.

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 )

Returns the number of entries in the table, for the use by plugins.

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 ( int * params )

Initialize an array PARAMS with default values of the
   parameters.

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, implicitly,
   if it has not been set explicitly by the user, in the table PARAMS
   using PARAMS_SET to indicate which have been explicitly 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.

Referenced by default_options_optimization(), and finish_options().

void set_default_param_value	(	compiler_param	num,
		int	value
	)

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

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 the
   table PARAMS using PARAMS_SET to indicate which have been
   explicitly set.

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