similar to: [LLVMdev] llvmc: Can't find program 'llvm-g++'

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

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

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

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 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: >

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, I'm currenly working with clang, so I don't have any llvm-gcc installed (I used to have the 4.2 release version, but that broke a lot of tests). A number of tests (test/CFrontend and test/C++Frontend for example) won't run if you don't have llvm-gcc installed, which is good. However, the test/LLVMC tests do run, but fail. These tests test the llvmc2 compiler driver, but they

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

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

Hi, Is it intended that llvmc should search PATH for llc? For example, this means that llvmc 2.7 can invoke llc 2.8: % echo $PATH /home/jdenny/installs/llvm/2.8/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games % /home/jdenny/installs/llvm/2.7/bin/llvmc test.ll llc: Unknown command line argument '-f'. Try: 'llc -help' % strace -f

Hi, Apparently there are two bugs in tools/llvmc/c: /.../llvm/tools/llvmc/c:12: Error: Invalid top level configuration item /.../llvm/tools/llvmc/c:28: Error: Expecting a program name /.../llvm/tools/llvmc/c had 2 errors.

Without this patch, opt is never called for llvm-assembly (.ll) files when "-opt" is passed to llvmc: $ llvmc -clang -v test.ll llc -f -O2 test.ll -o /tmp/llvm_gvO2nK/test.s as /tmp/llvm_gvO2nK/test.s -o /tmp/llvm_gvO2nK/test.o llvm-ld -native -disable-internalize /tmp/llvm_gvO2nK/test.o -o a.out $ llvmc -clang -opt -v test.ll llc -f -O2 test.ll -o /tmp/llvm_2xiL86/test.s as

According to the FAQ llvmc is considered experimental/unsupported. But FWIW, here's an issue I found while trying to use it on 32 bit x86 systems. tools/llvmc/plugins/Base/Base.td hardcodes the -relocation-model=pic option into invocations of llc: def llc : Tool< [(in_language "llvm-bitcode"), (out_language "assembler"), (output_suffix "s"), (cmd_line

Thank you so much for your reply, Chris. If so, can I ask you two things more? First, is there any way to have various optimizations on LLVM assembly such as -O options in llvmc? llvm-gcc doesn't seem to be working for these -O options... Second, I'm still not sure about difference between *.s and *.ll. LLVM assembly *.s file can be made from llvm-gcc -S. Another assembly *.ll file comes

Hello, guys. I've tried to use llvmc to test optimization options but wasn't successful.
