Function Documentation

void analyze_irg_args

(

ir_graph *

irg

)

Analyze how pointer arguments of a given ir graph are accessed.

Parameters

irg	The ir graph to analyze.

void analyze_irg_args_weight

(

ir_graph *

irg

)

Analyze the parameters of a given ir graph.

Parameters

irg	The ir graph to analyze.

ptr_access_kind get_method_param_access	(	ir_entity *	ent,
		size_t	pos
	)

Returns for a method with pointer parameter if they will be read or written.

Parameters

ent	The entity that represent this method.
pos	The position of method's parameter for that we need information.

If the pos'th parameter is NOT of a pointer type, ptr_access_none is returned;

unsigned get_method_param_weight	(	ir_entity *	ent,
		size_t	pos
	)

Returns for a method the 'weight' that every parameter has on optimization possibility.

Higher values allows higher optimization with procedure cloning.

The values are calculation on demand only.
