Hi, I notice that there are several different methods called inside getAnalysisUsage(). The parameters of addRequiredID and addPreservedID are passID. What is the difference between Required and Preserved? There are also function named addRequired<PassName>() called. What is the difference between addRequired<PassName>() and addRequiredID(PassID)? Thanks a lot! Best,...

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 Adding new type instructions from llvm.org site are out of date (http://llvm.org/docs/ExtendingLLVM.html#type).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?

Hello, I have two for loops (one inside the other), that after indvars, looprotate, etc. (the important here is the loop rotate), is similar to this (I've stripped the real operations): define i32 @f() nounwind { entry: br label %bb1 bb1: ; preds = %bb3, %bb1, %entry %i.0.reg2mem.0.ph = phi i32 [ 0, %entry ], [ %i.0.reg2mem.0.ph, %bb1 ], [ %indvar.next9, %bb3 ] ;
