Get the Init value of the specified bit.

◆ isComplete()

bool llvm::ExistsOpInit::isComplete ( ) const

Is this a complete value with no unset (uninitialized) subvalues?

Reimplemented from llvm::Init.

References ProfileExistsOpInit().

◆ resolveReferences()

const Init * ExistsOpInit::resolveReferences ( Resolver & R) const
overridevirtual

This function is used by classes that refer to other variables which may not be defined at the time the expression is formed.

If a value is set for the variable later, this method will be called on users of the value to allow the value to propagate out.

Reimplemented from llvm::Init.

Definition at line 2240 of file Record.cpp.
