[llvm-dev] llvm pass

[Varun Patil via llvm-dev]

I want to insert new alloca Instruction after existing alloca Instruction
in llvm pass so what attribute to be passed at last in following
newallocaI =  new AllocaInst(llvm::Type::getInt32PtrTy(context,0), //type
                                                0, // ArraySize
                                                8, // Alignment
                                                "p", // const

                                                allocaI);  // InsertBefore
Presently I am passing previous allocaInstr Poiter as last argument as i
shown above So New allocaInstr is inserting before previous allocaInstr in
LLVM IR as follows output

 %p1 = alloca i32*, align 8 // New Alloca Instrctions
 %b = alloca i32, align 4   // previous Alloca Instrctions

how can I get output like below
 %b = alloca i32, align 4   // previous Alloca Instrctions
 %p1 = alloca i32*, align 8 // New Alloca Instrctions

Please help me to the needful Thank you

Thanks and Regards
Varun
