Hi, I'm new to LLVM, and I'm trying to get things set up. So far I've successfully gotten the C and C++ frontends to run, using the pre-compiled Mac OS X PPC binaries. I've also successfully compiled the main LLVM package (minus the gcc frontend). I'm now trying to get the Stacker sample project to co...

Hello all, I am a LLVM newer who want to add a new backend(EBC) into LLVM. After coping the related files from another target and modifying it, I meet a problem when I build the project. The error message is as follows: ================================================================ [ 94%] Built target llvm-dis Linking...

Hi On Windows 10 when using a debug build of LLVM 10, I get this assertion failure: Assertion failed: (KV.second.getFlags() & ~WeakFlags) == (I->second & ~WeakFlags) && "Resolving symbol with incorrect flags", file C:\work\github\llvm-10.0.0.src\lib\ExecutionEngine\Orc\Core.cpp, line 450 The same failure occurred in...

Hi, I might just be doing something stupid, but when I do $ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/llvm-2.8 -DCMAKE_BUILD_TYPE=Release .. $ sudo make install I don't get the expected headers in /usr/local/llvm-2.8/include/llvm It is simply an empty directory.

Greetings, I am having trouble getting the Kaleidoscope example to build from tutorial #3 on Mac OS X 10.6.2. I didn't have too much trouble getting llvm-2.6 and llvm-gcc-frontend to build.

Hi I am trying to use latest version of llvm and clang, and I have gotten them by svn. ./configure --enable-shared has run successfully, but make REQUIRES_RTTI=1 returns error: make[2]: Entering directory `/home/ryjiao/Downloads/llvm-dev/llvm/tools/llvm-config' make[2]: Nothing to be done for `all'. make[2]: Leaving directory `/home/...

...ng to access any hardware. I am using clang to analysis the ARM binaries. The binary is 483.xalancbmk in CPU SPEC2006. When I use the optimization O0, no crash will occur. The crash occurs when I set optimization level as O1,O2,O3 and Os. If I have to recompile and rerun the tests. What version of llvm is suggested. It would be better if anyone could provide the patch on this bug.

...ar problem while linking the opt. In my case, I was not being able to create the shared library when enable-shared were passed through the configure script. I just had to realize that my default compiler was not being able to generate the binaries, probably because of its version (it was the stable llvm-gcc 4.1). Therefore, if I had compiled the llvm+clang from svn without the enable-shared flag, and installed it in some temp folder (configured in the PATH), I could use this one to configure and recompile the source with the flag enabled without this linkage error. I guess you could give it a try....
