similar to: Re-numbering address space with a pass

Hi Erdem, Since it is a target specific pass, you should put your pass inside the target's folder (e.g. lib/Target/X86/) and declare your pass in Target.h. Then you need to modify the target's TargetPassConfig ( http://llvm.org/docs/doxygen/html/classllvm_1_1TargetPassConfig.html) to enable your pass. You can check out the existing MachineFunction passes (e.g. X86ExpandPseudo.cpp) to get

This seems to be what I am looking for. That was very helpful. Thank you. Erdem From: vlknkls at gmail.com Date: Wed, 16 Sep 2015 16:25:29 +0000 Subject: Re: [llvm-dev] How to add NOP?

I would like to convert a C file that uses OpenMP library to X86 code with a condition: I want to insert a NOP before each instruction that does a private memory access.I have written an optimization pass that inserts an inline assembly call (NOP) but it is applied at IR level, and I cannot determine where to insert it. How can I use LLVM to add NOPs accordingly? Thanks. --------------

Hello all, I am developing an out-of-tree backend for a unique simd processor and I'm looking for a bit of help. In my current design, it's possible for a case to arise where I decide during instruction legalization that a fixed-sized array of vectors which has been initially allocated on the stack needs to be lowered into the vector register file. I have this design working for the case

Dear all, I would like to store thread local variables in a different address space than global variables in an OpenMP program. Is it possible to do it using LLVM (perhaps with an optimization pass)? Erdem Derebasoglu -------------- next part -------------- An HTML attachment was scrubbed... URL:

I had INITIALIZE_PASS_BEGIN and INITIALIZE_PASS_END macros. I replaced them with INITIALIZE_PASS but I get the same error. If I understand correctly, I need to modify Passes.h, InitializePasses.h, and Codegen.cpp files to register my pass, right? Another question is: Is it necessary to have the createNoopInserterPass function? Erdem -------------- next part -------------- An HTML

Hi, If the special handling in the meg2reg pass is to look for lifetime intrinsics, shouldn't it cast to <IntrisicInst> and then use getInstrinsicID to check for lifetime_start and lifetime_end ? The thing that I don't understand is the following piece of code, which finds all the users and cast it to <Instruction> then eraseFromParent(). How can this guarantee that it only

Hi, In PromoteMemoryToRegister.cpp, it seems to rely on the fact that the only users of bitcast/GEP instruction are lifetime intrinsics (llvm.lifetime.start/end). I did some searching in llvm/test folder, it seems to be true. However, by reading LLVM IR manual, I don't see any restriction stated on the possible user of bitcast/GEP instruction. So my question is who impose the restriction ?

I'd like to get a quick feedback on the lifetime.end metadata kind I'm considering using. I'm planning to use it in cases where lifetime.end intrinsics do not give lifetime bounds that are tight enough. As an example of when lifetime.end cannot provide a tight lifetime bound, consider the following program: void test111(int n) { if (n < 10) { string str = "One";
