[LLVMdev] llvm-mc build fails

[John Myers]

Hi,

I'm looking for some pointers on how to troubleshoot this problem. I'm
trying to write a backend for the AVR.
There is an undefined reference at line 48 which is the line FrameInfo() is
on. I've tried to use the MSP430 and other targets as references so I'm not
sure
what changes I did would cause a problem on this line?


AVRTargetMachine::AVRTargetMachine(const Target &T, const std::string &TT,
                                       const std::string &FS)
  : LLVMTargetMachine(T, TT),
    Subtarget(TT, FS),
    DataLayout("e-p:16:8:8-i8:8:8-i16:8:8-i32:8:8"),
    InstrInfo(Subtarget),
    TLInfo(*this),
    FrameInfo(TargetFrameInfo::StackGrowsDown, 1, 0) { }
