similar to: [LLVMdev] Problem while building llvm

Hi, all I come across the problem when building llvm. The errors are as follows ... etJITInfo&, llvm::JITMemoryManager*, llvm::CodeGenOpt::Level, bool)': : undefined reference to `__register_frame' collect2: ld returned 1 exit status make[2]: *** [/home/lishengmei/llvm-2.6/Release/bin/lli] Error 1 make[2]: Leaving directory `/home/lishengmei/llvm-2.6/tools/lli'

Hi, all I use llvm-gcc -O4 to compile SPEC 2000, some benchmarks can't be built successfully, such as 164.gzip, 175.vpr etc. The error messages are as follows. .. zh.o unlzw.o unpack.o unzip.o util.o zip.o -o gzip bits.o: file not recognized: File format not recognized collect2: ld returned 1 exit status specmake: *** [gzip] Error 1 specmake options 2> options.err |

I found the following problem when I try to debug "target does not support mc emission" in linux (the same code executes OK in windows): Below is a snippet extracted from this method, if (UseMCJIT && ExecutionEngine::MCJITCtor) { ExecutionEngine *EE = ExecutionEngine::MCJITCtor(M, ErrorStr, JMM, OptLevel,

Thanks, sands My gcc version is 3.4.6. Any problems? Shengmei ---------------- Hi, > / : undefined reference to `__register_frame' / this is defined in libgcc on most platforms and is used for registering exception handling frames. LLVM's JIT makes use of it on some platforms. What version of gcc are you using? Ciao, Duncan.

Hello everyone, i’m using LLVM (updated to 3.1 after seeing that bug, but it’s the same with 3.0) for running a bitcode on a C++ program, and Clang for compiling it. My code work perfectly, as expected on x64, but crash on x86. I’m on Windows 7 x64 and LLVM + Clang was compiled using Visual Studio 2010 (tested in both Release and Debug build). Project was make using CMake. Here is my code:

Hi Evan, My apologies: I've been so excited on sharing the functionality that I forgot to review my patch!

Nobody give comments on this? Is the source to source transformation of LLVM robust enough? Thanks in advance. Shengmei _____ Problems of source to source transformation of LLVM Hi, I did experiments of the source transformation of LLVM on SPEC2000 C programs. But I found most benchmarks can't be transformed from source to source successfully. The steps are as

Hi, all We want to learn the IR of LLVM. Are there any information or documents you can suggest? Or any suggestions are welcome.

Hi, I want to know what benchmarks can LLVM compile and run successfully. Such as SPEC CPU2000, SPEC CPU2006 or other benchmarks.

Hi Paul, I'm surprised to hear that you aren't seeing any adverse effects. As I understand it, the memory for the function pointer returned by getPointerToFunction is owned by the JITMemoryManager which was used in creating the ExecutionEngine. In the case of the legacy JIT engine, the JITMemoryManager is owned by the JITEmitter which in turn is owned by the JIT ExecutionEngine. In the
