◆ ~Metadata()

llvm::Metadata::~Metadata ( ) protecteddefault

◆ dump() [1/2]

User-friendly dump.

If M is provided, metadata nodes will be numbered canonically; otherwise, pointer addresses are substituted.

Note: this uses an explicit overload instead of default arguments so that the nullptr version is easy to call from a debugger.

◆ handleChangedOperand()

void llvm::Metadata::handleChangedOperand ( void * , Metadata * ) inlineprotected

Default handling of a changed operand, which asserts.

If subclasses pass themselves in as owners to a tracking node reference, they must provide an implementation of this method.
