Hi: I want to pass some message of instructions from LLVM Internal representation to backend code. For example, I make a flag for some certain operands of certain instructions. How can it be passed to the backend instructions? Which programs I should look into? Would someone give me some idea? Thank you ! -- Shuhan

As a simple example of this, you can take a look at how the PHINode class has an extra 'reservedspace' member (ignore what it is used for though), or the load/store instructions track the 'isVolatile' flag. -Chris -- http://nondot.org/sabre/ http://llvm.cs.uiuc.edu/

All, Is it possible to create something which has the same effect of a variable-length phi node in the C++ api. Specifically, create a phi-node where the number of incoming values is not known at the time of its creation. If there is no such way of creating a phinode like that, would it be possible to create a dummy instruction and perform a replaceAllUsesWith? If so, what should the dummy
