Function Documentation

void add_compound_ent_value	(	ir_entity *	ent,
		ir_node *	val,
		ir_entity *	member
	)

Beware: Has a bad runtime for array elements (O(|array|) and should be avoided there. Use add_compound_ent_value_w_path() instead and create the path manually.

void add_compound_ent_value_w_path	(	ir_entity *	ent,
		ir_node *	val,
		compound_graph_path *	path
	)

int entity_has_compound_ent_values

(

const ir_entity *

entity

)

void free_compound_graph_path

(

compound_graph_path *

gr

)

size_t get_compound_ent_n_values

(

const ir_entity *

ent

)

Asserts if the entity has variability_uninitialized.

ir_node* get_compound_ent_value	(	const ir_entity *	ent,
		size_t	pos
	)

ir_node* get_compound_ent_value_by_path	(	const ir_entity *	ent,
		compound_graph_path *	path
	)

The path must contain array indices for all array element entities.

ir_entity* get_compound_ent_value_member	(	const ir_entity *	ent,
		size_t	pos
	)

unsigned get_compound_ent_value_offset_bit_remainder	(	const ir_entity *	ent,
		size_t	pos
	)

This requires that the layout of all concerned types is fixed.

Parameters:

ent	Any entity of compound type with at least pos initialization values.
pos	The position of the value for which the offset is requested.

unsigned get_compound_ent_value_offset_bytes	(	const ir_entity *	ent,
		size_t	pos
	)

This requires that the layout of all concerned types is fixed. Asserts if bit offset is not byte aligned.

Parameters:

ent	Any entity of compound type with at least pos initialization values.
pos	The position of the value for which the offset is requested.

compound_graph_path* get_compound_ent_value_path	(	const ir_entity *	ent,
		size_t	pos
	)

long get_compound_graph_path_array_index	(	const compound_graph_path *	gr,
		size_t	pos
	)

size_t get_compound_graph_path_length

(

const compound_graph_path *

gr

)

ir_entity* get_compound_graph_path_node	(	const compound_graph_path *	gr,
		size_t	pos
	)

ir_type* get_compound_graph_path_type

(

const compound_graph_path *

gr

)

int is_compound_graph_path

(

const void *

thing

)

int is_proper_compound_graph_path	(	compound_graph_path *	gr,
		size_t	pos
	)

If the path contains a NULL, assumes the path is not complete and returns non-zero.

compound_graph_path* new_compound_graph_path	(	ir_type *	tp,
		size_t	length
	)

void remove_compound_ent_value	(	ir_entity *	ent,
		ir_entity *	value_ent
	)

Does not free the memory of the paths. (The same path might be used for several constant entities.

void set_array_entity_values	(	ir_entity *	ent,
		ir_tarval **	values,
		size_t	num_vals
	)

The array must have a lower and an upper bound. Keeps the order of values. Does not test whether the number of values fits into the given array size. Does not test whether the values have the proper mode for the array.

void set_compound_ent_value	(	ir_entity *	ent,
		ir_node *	val,
		ir_entity *	member,
		size_t	pos
	)

void set_compound_ent_value_w_path	(	ir_entity *	ent,
		ir_node *	val,
		compound_graph_path *	path,
		size_t	pos
	)

void set_compound_graph_path_array_index	(	compound_graph_path *	gr,
		size_t	pos,
		long	index
	)

void set_compound_graph_path_node	(	compound_graph_path *	gr,
		size_t	pos,
		ir_entity *	node
	)
