read/write analyze of graph argument, which have mode reference

Definition in file analyze_irg_args.h.

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.
