Modules
	Class
	If the type opcode is set to type_class the type represents class types.
	Struct
	A struct type represents aggregate types that consist of a list of fields.
	Union
	The union type represents union types.

Detailed Description

Function Documentation

void default_layout_compound_type

(

ir_type *

tp

)

layout members of a struct/union or class type in a default way.

ident* get_compound_ident

(

const ir_type *

tp

)

Returns the identifier of a compound type.

ir_entity* get_compound_member	(	const ir_type *	tp,
		size_t	pos
	)

Returns the member of a Firm compound type at position pos.

Parameters

tp	The type (must be struct, union or class).
pos	The number of the member.

Returns

The member entity at position pos.

size_t get_compound_member_index	(	ir_type const *	tp,
		ir_entity const *	member
	)

Returns index of member in tp, -1 if not contained.

size_t get_compound_n_members

(

const ir_type *

tp

)

Returns the number of elements in a Firm compound type.

This is just a comfortability function, because structs and classes can often be treated be the same code, but they have different access functions to their members.

Parameters

tp	The type (must be struct, union or class).

Returns

Number of members in the compound type.

const char* get_compound_name

(

const ir_type *

tp

)

Returns compound identifier as c-string.

int is_compound_type

(

const ir_type *

tp

)

Checks whether a type is a compound type.

Parameters

tp	- any type

Returns

true if the type is class, structure, union or segment type.

void remove_compound_member	(	ir_type *	compound,
		ir_entity *	entity
	)

Remove a member from a compound type.
