typedef struct param_info param_info

   The information associated with each parameter.

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.

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.  

void global_init_params

(

void

)

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

References params_finished.

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.  

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.  

     Make sure nobody tries to set a parameter to an invalid value.  

     Scan the parameter table to find a matching entry.  

     If we didn't find this parameter, issue an error message.
