Hi, I found out that Auto-Vectorization was implemented as a part of GSoC 2009. Can someone point me to the code repository including any documentation available? I would also like to know if there is any progress/future plans to include this in the main trunk? Best Regards, Raj

hi, we are developing a plugin(http://wiki.llvm.org/Polyhedral_optimization_framework) for LLVM, and need to find the LLVM libraries directory so we can locate the loadable module. The testing guide said that we can locate the libraries directory by the variable "$llvmlibsdir". So i put this option after opt in the RUN line of test case: -load=$llvmlibsdir/LLVMPolly.so. bu...

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 the ideas that can be implemented in Polly is listed below. Please let me know your comments on this. 1. Increas...

Hi all, I would like to participate in Google's Summer of Code this year, for LLVM(Polly), The polyhedral optimization framework ( http://wiki.llvm.org/Polyhedral_optimization_framework ) which i am already working on with Tobias. Polly is a polyhedral optimization framework for llvm, which similar to Graphite for gcc (http://gcc.gnu.org/wiki/Graphite). The main work flow of Polly is: 1. Transfer LLVM IR to polyhedral model represent (Polyhedral IR) with the LLVM Region fra...

...oal is to drive vectorization and openmp parallelism with polly. Furthermore I know of at least one project working on OpenMP support for clang, which is unfortunately not public. I tried to ping the guys to check if they are interested in giving it back to LLVM. Tobi [1] http://wiki.llvm.org/Polyhedral_optimization_framework

...y". Folks, is anyone interested mentoring this tasks for me? I have some practical experience in parallel programming with MPI, OpenMP, participated at university autoparallezation research. So this work is linked with my activity and I believe I can handle it.

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
