Detailed Description

Function Documentation

ir_type* clone_frame_type ( ir_type * type )

Makes a clone of a frame type.

Sets entity links from old frame entities to new onces and vice versa.

Allocate an area of size bytes aligned at alignment at the start or the end of a frame type.

The frame type must already have a fixed layout.

Parameters

frame_type	a frame type
size	the size of the entity
alignment	the alignment of the entity
at_start	if true, put the area at the frame type's start, else at end

int is_frame_type ( const ir_type * tp )

Checks, whether a type is a frame type.

ir_type* new_type_frame ( void )

Makes a new frame type.

Frame types are class types, so all class access functions work. Frame types are not in the global list of types.
