[cfe-dev] clang fails to build with latest LLVM revision

[Chris Lattner]

It looks like the mainline interfaces were changed.  Before it used  
to have several versions, including one that took a an array of  
operands as a base pointer + count, now it only takes two iterators  
as input.

Please change stuff like this:
   llvm::Value *ImagPtr = Builder.CreateGEP(SrcPtr, Zero, One,  
Name.c_str());

to:

   Value *Ops[] = {Zero, One};
   llvm::Value *ImagPtr = Builder.CreateGEP(SrcPtr, Ops, Ops+2,  
Name.c_str());

and it should work.
