Detailed Description

The array type represents linear arrangement of objects of the same type.

• *size: number of elements in the array.
• *element_type: The type of the array elements.

Function Documentation

ir_type* get_array_element_type

(

const ir_type *

array

)

Returns the array element type.

ir_node* get_array_size

(

const ir_type *

array

)

Returns the size (number of elements) of an array.

unsigned get_array_size_int

(

const ir_type *

array

)

Works only if bound is Const node with tarval that can be converted to long.

int has_array_size

(

const ir_type *

array

)

returns true if lower size != Unknown

int is_Array_type

(

const ir_type *

array

)

Returns true if a type is an array type.

int is_array_variable_size

(

const ir_type *

array

)

Returns the array variable size flag.

set_array_variable_size()

ir_type* new_type_array

(

ir_type *

element_type

)

Create a new type array.

void set_array_element_type	(	ir_type *	array,
		ir_type *	tp
	)

Sets the array element type.

void set_array_size	(	ir_type *	array,
		ir_node *	size
	)

Sets the size (number of elements) of the array, i.e.

[0,size[

void set_array_size_int	(	ir_type *	array,
		unsigned	size
	)

Sets array size of array to size elements.

void set_array_variable_size	(	ir_type *	array,
		int	variable_size_flag
	)

Sets the array variable size flag.

If this flag is set then no upper/lower bounds need to be set and get_type_size_bytes() returns -1
