void DerivedType::notifyUsesThatTypeBecameConcrete

(

)

[protected]

notifyUsesThatTypeBecameConcrete - Notify AbstractTypeUsers of this type that the current type has transitioned from being abstract to being concrete.

Definition at line 1436 of file Type.cpp.

References llvm::Type::AbstractTypeUsers, DOUT, and llvm::AbstractTypeUser::typeBecameConcrete().

void DerivedType::dropAllTypeUses

(

)

[protected]

dropAllTypeUses - When this (abstract) type is resolved to be equal to another (more concrete) type, we must eliminate all references to other types, to avoid some circular reference problems.

Definition at line 529 of file Type.cpp.

References llvm::Type::ContainedTys, llvm::OpaqueType::get(), and llvm::Type::NumContainedTys.

void DerivedType::refineAbstractTypeTo

(

const Type *

NewType

)

refineAbstractTypeTo - This function is used to when it is discovered that the 'this' abstract type is actually equivalent to the NewType specified. This causes all users of 'this' to switch to reference the more concrete type NewType and for 'this' to be deleted.
