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

Hi: I have extended the IR for adding flag. But I just want this flag to pass through the backend machine code. I know there're several passes like register relocation, schedualing, etc. But I think I just miss the part which is used to "parser" the LLVM IR to machine code instructions. Would you give me some help? Thank you ! > On Sun, 10 Jul 2005 shding at mtu.edu wrote:

Hi, In the directory of lib/CodeGen/SelectionDAG, I cann't find SelectionDAGISel.cpp. I only have DAGBuilder.cpp and SelectionDAG.cpp. I don't know why. My edtion is 1.4. Is it because of the edtion difference? Thanks! > On Mon, 11 Jul 2005 shding at mtu.edu wrote: >> I have extended the IR for adding flag. But I just want this flag to >> pass through the backend
