Detailed Description

Trouts list all uses of types and entities.

Each type gets a list of all Alloc nodes allocating it. Each entity gets two lists:

one containing all accesses (Load, (Call), Store),
and one containing all uses to get a reference (Sel, SymConst).

Function Documentation

void compute_trouts ( void )

Computes the outs of types and entities.

Collects all reference from irnodes to types or entities in the corresponding types/entities. Further reverses references between types and entities.

Annotates the following nodes: Alloc –> get_Alloc_type() Cast –> get_Cast_type() Sel –> get_Sel_entity() SymConst –> get_SymConst_entity() Load(addr) –> get_addr_entity() \ ent von SymConst, oder falls Sel: ent von Store(addr) –> get_addr_entity() / outermost im compound. Ansonsten: nirgends. d.h. wir bekommen die array Elementzugriffe an die jack array Klasse annotiert. Call(Sel) –> get_Sel_entity() // ev. Tabellenzugriff –> Load.

type –> pointer type refering to this type. type –> entity of this type. @@ to be implemented.

Sets trout state to outs_consistent.

void free_trouts ( void )

Frees trout data.
