Methods

ASTCallbackVH(
    llvm::Value* V,
    llvm::AliasSetTracker* AST = nullptr)

Declared at: llvm/include/llvm/Analysis/AliasSetTracker.h:332

Parameters

llvm::Value* V
llvm::AliasSetTracker* AST = nullptr

void allUsesReplacedWith(llvm::Value*)

Description

Callback for Value RAUW. Called when this->getValPtr()->replaceAllUsesWith(new_value) is called, _before_ any of the uses have actually been replaced. If WeakTrackingVH were implemented as a CallbackVH, it would use this method to call setValPtr(new_value). AssertingVH would do nothing in this method.

Declared at: llvm/include/llvm/Analysis/AliasSetTracker.h:329

Parameters

llvm::Value*

void deleted()

Description

Callback for Value destruction. Called when this->getValPtr() is destroyed, inside ~Value(), so you may call any non-virtual Value method on getValPtr(), but no subclass methods. If WeakTrackingVH were implemented as a CallbackVH, it would use this method to call setValPtr(NULL). AssertingVH would use this method to cause an assertion failure. All implementations must remove the reference from this object to the Value that's being destroyed.
