Just noticed that quite a few passes like LoopSimplify are implemented in a single .cpp file ... this makes it impossible to specify LoopSimplify using the "addRequired" method. Was there any particular reason to do it this way? I wouldn't mind doing the splitting myself, though I am not using the CVS versions right now. Also, it would be nice to have support for some sort of a

Try adding "AU.addRequiredID(LoopSimplifyID);AU.addPreservedID(LoopSimplifyID);" to your transformation pass. -Eli

Hello . I would like to add new custom data type to llvm C parser, I use LLVM/Clang version 3.1. Adding new type instructions from llvm.org site are out of date (http://llvm.org/docs/ExtendingLLVM.html#type). Could you please provide me with guidance?
