Definition at line 1657 of file CGExprConstant.cpp.
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.

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.

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.
