◆ ConstantEmitter() [2/3]

clang::CodeGen::ConstantEmitter::ConstantEmitter ( CodeGenFunction & CGF )

inline

Initialize this emission in the context of the given function.

Use this if the expression might contain contextual references like block addresses or PredefinedExprs.

Member Function Documentation

◆ emitAbstract() [1/2]

llvm::Constant * ConstantEmitter::emitAbstract	(	const Expr *	E,
		QualType	T
	)

Emit the result of the given expression as an abstract constant, asserting that it succeeded.

This is only safe to do when the expression is known to be a constant expression with either a fairly simple type or a known simple form.

◆ getCurrentAddrPrivate()

llvm::GlobalValue * ConstantEmitter::getCurrentAddrPrivate ( )

Get the address of the current location.

This is a constant that will resolve, after finalization, to the address of the 'signal' value that is registered with the emitter later.

Is the current emission context abstract?

◆ registerCurrentAddrPrivate()

void ConstantEmitter::registerCurrentAddrPrivate	(	llvm::Constant *	signal,
		llvm::GlobalValue *	placeholder
	)

Register a 'signal' value with the emitter to inform it where to resolve a placeholder.

The signal value must be unique in the initializer; it might, for example, be the address of a global that refers to the current-address value in its own initializer.

Uses of the placeholder must be properly anchored before finalizing the emitter, e.g. by being installed as the initializer of a global variable. That is, it must be possible to replaceAllUsesWith the placeholder with the proper address of the signal.
