This is the common base class of value handles.

ValueHandle's are smart pointers to Value's that have special behavior when the value is deleted or ReplaceAllUsesWith'd. See the specific handles below for details.

◆ HandleBaseKind

This indicates what sub class the handle actually is.

This is to avoid having a vtable for the light-weight handle pointers. The fully general Callback version does have a vtable.

◆ clearValPtr()

void llvm::ValueHandleBase::clearValPtr ( ) inlineprotected

Clear the underlying pointer without clearing the use list.

This should only be used if a derived class has manually removed the handle from the use list.
