void add_params ( )
   Add the N PARAMS to the current list of compiler parameters.  
     Allocate enough space for the new parameters.  
     Copy them into the table.  
     Keep track of how many parameters we have.  
int default_param_value ( )
   Return the default value of parameter NUM.  

References num_compiler_params.

void finish_params ( void  )
   Note that all parameters have been added and all default values

References params_finished.

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.  
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 ( )
   Initialize an array PARAMS with default values of the
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
void set_default_param_value ( )
   Set the default value of a parameter given by NUM to VALUE, before
   option processing.  

References num_compiler_params, and params_finished.

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