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 ?

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: >

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

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, 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 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

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 list, As long as I know English the word "bit" is a "small pice", . Why in set of documentation ir is "bytecode", in other set or llvm source is "bitecode"? What is the right?

Hello, I am using gdb to debug the -instcount pass. The steps I followed were: 1. gdb opt 2. break llvm::PassManager::run 3. run -stats -analyze -instcount filename.bc I got the bc file using -emit-llvm option as following: llvm-gcc -O3 -emit-llvm filename.c -c -o filename.bc But when I started debugging, the debugger never really went into my bitecode file, filename.bc and it returned me the

When you say "spit bitecode from the JIT the first time, load it on subsequent sessions" : - do you want to write the IR in a file via BitcodeWriter and re-read it via BitcodeReader ? (you will pay the cost of native code emission on each load ?) - do you want to write the native code ? In that case, how do you retrieve the size of the buffer prepared by the

Hello everyone I've a following problem with the speex codec. I'm developing application that is supposed to read sounds from the microphone with DirectSoundCapture. Unfortunately when I want to compress and decompress the sound buffer from DirectSound I only have jitter. Maybe you have some code samples how to compress standard DS buffers: LPDIRECTSOUND8 lpDS = NULL;
