similar to: [LLVMdev] debugger doesn't go inside the bitecode file

Hello, I am getting to know how the Runtime Optimization feature of LLVM works and how I can use it. I want to know how I could print the results of any analysis and transformation pass. Say, I have a program written in c and I ran the edge-profiling pass onto it. Now I want to see the result. How could I do it? Also if I happen to change one of the passes inside folder

The patch file is a diff file generated by "svn diff". It is about other modifications such as adding some lines to make files to make the added .c and .cpp files compiled. You may apply the patch file to LLVM source code by using a "patch" command or make the changes manually by reading the patch file. Xiaoming On Wed, Sep 28, 2011 at 6:05 AM, Himanshu Shekhar

Hello guys, I am trying to know how clang generates AST from source code. But it is not clear for me how clang generates it. Can you tell me which class or function of clang is building/generating AST? I want to see the specific function or algorithm of clang which generates AST. Thanks in advance for your idea.

Hello, What you're describing is basically the parsing and codegen portions of clang. I'd suggest reading through the code there and posting to clang-dev if you have any specific questions. The clang devs are more likely to see your questions there as not all of them also hang out here. Regards, Jim On Sep 28, 2011, at 8:28 PM, eyasu getahun <eya.get at gmail.com> wrote: >

Hey guys, I have seen your interesting conversion. I am new for LLVM as well as clang compiler. I am going to use it now. it is quite difficult when someone starts it from scratch. But it is enjoyable and it is possible to familiarize with the environment by short time. Am gonna to use clang + llvm to generate AST from source code by using clang and to do high level transformation. Then I want to

Hey Xiaoming, Thanks for those source codes. Can you please explain what this llvm-memory-profiling.patch does ?

Hi, I was trying to write a LLVM Pass, so I first read http://llvm.org/docs/WritingAnLLVMPass.html#quickstart about how to write a llvm pass. Here, under setting up the build environment settings, it was instructed to configure and build LLVM directly inside the LLVM source tree rather than in a separate objects directory. Now, my LLVM source tree is C:\LLVM\llvm-2.9 while my build is in

Hi, Himanshu. I once wrote an LLVM IR-based memory profiling pass. Basically, I followed the code for EdgeProfiling. The source code is enclosed here, which worked with LLVM 2.8. Hope it is helpful. MemoryProfiling.cpp---the instrumentation pass, which inserts profiling function calls into the original program MemoryProfiling.c---the profiling library containing the profiling calls

I am getting this error while using the command "llvmc -O3 -Wall hello.cpp" where hello.cpp is some cpp file on my machine. llvmc is the driver calling a bunch of tools like llvm-g++, opt, llc etc. I think the llvmc tool could not probably locate the llvm-g++ tool. I would like to know where should I specify the path to llvm-g++ for llvmc to find them. Also can someone give me the link

Hey chenwj, Thanks for the reply.Actually, I tried Cygwin to get things work on windows.Any idea how does it compare with MinGW?

Hey John, Thank you for the detailed reply. I tried to figure out myself which IR should I use for my purpose ( Clang's Abstract Syntax Tree (AST) or LLVM's SSA Intermediate Representation (IR). ), but couldn't really figure out which one to use. Here is what I m trying to do. Given any C/C++ program (like the one given below), I am trying to insert calls to some function, before and

Hi, I'm trying to compile the benchmarks from Mibench suite with the application of the all LLVM's tranformation passes. Moreover, I'm trying to generate assembly code for Mips architecture for extraction of energy and performance metrics. For this, for example, initially I compile the sources and link them generating a bitecode file. After, I apply each optimization using opt tool:

I just read that LLVM project could be used to do static analysis on C/C++ codes using the analyzer Clang which the front end of LLVM. I wanted to know if it is possible to extract all the accesses to memory(variables, local as well as global) in the source code using LLVM. Is there any inbuilt library present in LLVM which I could use to extract this information. If not please suggest me how to

Here I assume that your llvm-gcc is for x86-64-linux, since there was no MIPS release. So, you're feeding x86-oriented IR to MIPS backend. This won't work, you will need to provide MIPS-aware IR. Also, in 2.9 the MIPS was definitely not so mature. Hopefully

Thanks a lot Chris. Regarding basic block size I wish to calculate both: - The number of bytecode bytes - The number of machine code bytes for some target?

Hi, I am new to llvm and have read all the documents and managed to get the llvm tool working on linux without much problem. I am trying to generate some static analysis information about my program using llvm virtual machine architecture. the file is really simple hello world program with a small loop which increments a variable until a particular iteration. main() { int a,b,c; a=0; b=0; c=1;
