Hi, I am trying to use the new LLVM-2.7 release in Xcode for my analysis and development. However, I do not see the top level Xcode directory as in LLVM-2.6. Can someone tell me how to develop on top of LLVM-2.7 using Xcode? Best Regards, Raj

Try using cmake: http://www.llvm.org/docs/CMake.html

Hi, I am wondering if there is any generic graph data structure along with its traversal routines already available in LLVM-2.7. In particular, I am looking for creating both directed and undirected graphs and be able to perform dfs, topsort, and scc on them. Best regards, Raj

Hi Nadav, Unfortunately I'm not attending the dev meeting, but the BoF looks interesting. One thing that I'd like to throw into the mix is that, while dealing with autovectorisation of LLVM compiled down from C-like languages (or maybe Fortran-like languages) is clearly a very big area for fruitful work both algorithmically and in terms of practical relevance, it'd also be interesting

In trying to set up a LLVM development environment, CMake seemed "too easy" - cmake <srctree>. No configuration options necessary whatsoever. But it worked, at least for Xcode on MacOS and for Visual Studio on Windows. Builds were successful. I have not tried running any of the output yet, though, since I don't yet have a front-end set up. Yet in discussion here, a lot of

Hi all, I'm unable to compile R under an HPC system (which like many HPC systems doesn't always have the latest and greatest software). The version of GCC is 4.1.2 under CentOS 5.7. Running ./configure gives the following output: R is now configured for x86_64-unknown-linux-gnu Source directory: . Installation directory: /home/tbarik C compiler: gcc

Hello Everyone, I've been looking at benchmarks of LLVM recently, and overall they look pretty good. Aside from things that use OpenMP or benefit from autovectorisation, Clang/LLVM and GCC seem to come fairly close, with no overall winner. But: there do seem to have been a number of performance regressions between 2.9 and 3.0: http://openbenchmarking.org/result/1110178-AR-1110173AR66

Hi folks, I like open technologies, epecially LLVM compiler. I want to implement a new interface layer in LLVM to plug-in optimizers as a part of GSoC, and then load the interface with optimizers. This would improve LLVM application for people who want to use their optimizations in compilers. The first "educative" step is to add Doxygen (for .h files) to the build and integrate it

LLVM already has a plug-in framework for loading new analysis and optimization passes

Dear all, I am Raghesh, a student pursuing M.Tech at Indian Institute of Technology, Madras, India. I would like to make contribution to the Polly project (http://wiki.llvm.org/Polyhedral_optimization_framework) as part of GSOC 2011. I have gained some experience working in OpenMP Code generation for Polly. This is almost stable now and planning to test with the polybench benchmarks. Some of

hi all, The patch in the attachment add a new pass - region pass to the llvm system. A region pass is similar to a loop pass, all of them execute on a group of BasicBlocks at one time, but it operate on a single entry single exit region, not the nature loop. The original purpose to add such a pass to llvm system is to allow us find out the static control part (SCoP) for the polyhedral
