Hi all, Unfortunately, all my Hunks are failed when I apply : patch -p1 < da.patch command. The problem might be due to the fact that da.patch file was created against revision 167549, but I am on revision 167719 (I believe the most recent one). I am not sure if this cause the problem ? But Preston may I ask you to generate the patch file against revison 167719 ? Thanks in advance. On

Hello, I'm currently trying to develop new LLVM Pass that will generate simple data dependencies graph. For now I'm trying to get familiar with DependenceAnalysis. My general idea is to traverse each function (runOnFunction) top to bottom Instruction by Instruction, using DA.depends( I, I2, ...) on every Instructions combination in function to check if they are dependent on any

Dear all, I have already checked some related posted messages, such as: http://lists.cs.uiuc.edu/pipermail/llvmdev/2008-January/012315.html and http://lists.cs.uiuc.edu/pipermail/llvmdev/2008-February/012466.html After getting rid of some error messages, I was able to run the following commands: 1) opt -insert-path-profiling matmul.bc -o matmul.pp.bc 2) lli -load

Dear all, I want to build an LLVM pass by using CMake. After reading the ralevant part of the documentation ( http://llvm.org/releases/3.1/docs/CMake.html#passdev), I copied the files in the llvm/lib/Transforms/Hello to another folder in order to give a try. Then I renamed the folder as Hello2. Then I have changed CMakeLists.txt as following: cmake_minimum_required(VERSION 2.8) # A

What version of LLVM are you using? The profiling framework is completely messed up in the newer versions of LLVM.. I used to work with profiling in 2.5 some time ago, and it seemed to work fine.. If you really need this to work quickly, you might want to just get the old version and get on with it.. The newer versions of LLVM need to get the profiling part fixed soon..It is messing up my work as

Preston, thanks for the explanation and patch. Now it's printing the direction and distance values.

Erkan, you're right. Sorry about that. Attached is the most recent version. Preston Hi Preston, > I am trying to use DA as well.

Hi Guys, I noticed that the operation actions( promote/expand/custom) are set per operation basis. Wondering if we can set it up globally? For example, I have native supported 32 bits registers, to handle 8 bits value operations, I want to do promote. and to support 64 bit operations, I want to expand. If I can set up the operation actions for the same type globally, then I can avoid to

Hi everyone! Here, I have a question and am curious about i128. I want to know how the LLVM handle i128, because many compiler backend doesn't support i128 directly. So I am very curious and want to how the llvm handle this situation? Besides i128, such as i256, i512, even i24? Thanks.

Hey there! I've started to embark on a path to try and create a backend for a 39 year old CPU with only an accumulator, two index registers, and a 256 byte stack. It does have a bank of 256 bytes before the stack that are pretty quick though. Really, if I can get an assembler out of `llc`, that'll be success enough for me. Clang would be better, but I think that might be crazy talk.

Hi, I am new to LLVM and I find TableGen language really cryptic. The reference manual to the language is not helpful either. I can look at the existing .td file and reverse engineer but I am looking for a detailed manual. Specifically, I have below questions: 1. What is a basic syntax for writing a dag? From the lang ref manual I can see that its something like operator followed by ArgList which

Hi, The DependenceAnalysis pass will find loop-carried dependences. However, it is a conservative analysis and will sometimes suggest there may be more dependences than actually exist. In your example, I expect the analysis is confused for some reason and is returning the default confused response. You could test it using the isConfused() method. Note that the DVEntry::ALL direction is always

Hello. I am using the post-RA (Register Allocation) scheduler to avoid data hazards by inserting other USEFUL instructions from the program (besides NOPs) and it breaks apart some sequences of instructions which should remain "glued" together. More exactly, in my [Target]ISelDAGToDAG.cpp it is possible that I replace for example a BUILD_VECTOR with a machine SDNode called

I am interested in developing a backend for the PIC microcontrollers. Specifically, I plan to write for the 8-bit MCUs, but would hopefully also support the 16 and 32 bit models (eventually). It is my understanding that a backend for PIC16 was previously a part of the project but was dropped in version 2.9. Is there any development on this front currently? Is there any interest in developing this
