Sir, your answer put me in starting situation.As I told I am not able to generate .bc file of hello.cpp(the pass file) as it is giving errors when I use clang -emit-llvm -c hello.cpp -o hello.bc.So please if you can help me.

...ns(StringMap<Option*>& map) to get a map that maps strings (e.g. "help") to the Option* . This gives the client a lot of control over options. I made an example project that demonstrates my changes to the LLVM CommandLine library. Here's some of the code. https://github.com/delcypher/sample-llvm-cmd/blob/master/tools/sample/main.cpp Cheers, Dan.

Hi all, I can't seem to get the simplest CMakeLists.txt file working from http://llvm.org/docs/CMake.html#embedding-llvm-in-your-project. Do any of the LLVM projects use `find_package(LLVM REQUIRED CONFIG)`? Should I just be using `llvm-config` directly? http://llvm.org/bugs/show_bug.cgi?id=20884 David

Indeed! It seems that the people relying on our apt service wouldn't bother much where we move it to. So, I'm ok with any solution that replaces the functionality.

...a client at minimum ``-std=c++11 -f-no-rtti`` are needed. This information is shown by the ``llvm-config --cxxflags`` command but why aren't we exposing this information in LLVMConfig.cmake so clients can make use of it. For example in [1] I had to specify these by hand. [1] https://github.com/delcypher/srg-llvm-pass-tutorial [2] http://llvm.org/docs/CMake.html#embedding-llvm-in-your-project Thanks, Dan Liew.

...impler but not very useful because it means those who want to use the official LLVM binary release builds on their machine can't unless they have root access (so they can write to /usr/local/).

Mixing LLVM built with NDEBUG defined but then including LLVM header files in a project with NDEBUG not defined can lead to trouble (e.g. trying to use facilities in llvm/Support/Debug.h causes problems).

Hi, I'm currently working on the KLEE tool that uses LLVM (2.9 because that's what KLEE currently uses) and in particular I'm having an unexpected problem with the llvm::cl::bits class. I try something like this... enum testx { A,B }; cl::bits<testx> queryLoggingOptions("option",cl::values( clEnumVal(A,"this is a"),

Hi, I'm having problems compiling llvm-gcc-4.2-2.9 (from [1]). I need to use this version because I am trying to use KLEE (see [3]) which needs these versions. I am compiling on Arch Linux using gcc (GCC) 4.7.0 20120505 (prerelease) the output of `gcc -v` can be found at http://pastebin.com/8j2m3wzD I have tried the following 1. Extracted llvm-2.9 (from [2]) 2. Applied a patch (adds
