...n. For the same reason, I have tried to re-use as much as possible what LLVM/CLANG offers: compiler, jit, build system, diagnostic routines, testing infrastructure, ... Currently I have implemented an OpenCL backend for i386 and X86_64 CPUs. I have coded work-item stacks by hand because after some sintetic benchmarks I have observed that both ucontext and setjmp/longjmp contain some extra overheads. Code is not fully documented -- sorry -- and some mandatory features are still missing (e.g. local variables). Looking at the code, you can observe that there are a lot of LLVM passes. I have implemente...

If you have not already seen it, you (and anyone else working on OpenCL runtimes) might be interested in this paper from AMD: http://dl.acm.org/citation.cfm?id=1854302 In particular, Section 4...

Do we have a list of these open-source LLVM-based OpenCL projects somewhere? Off the top of my head, we have: libclc: http://www.pcc.me.uk/~peter/libclc/ pocl: https://launchpad.net/pocl clover: http://cgit.freedesktop.org/~steckdenis/clover/ (I think that all of these have BSD- or MIT-style licenses). Are there any others? -Hal On Wed, 2011-10-19 at 14:47 +0100, Peter Collingbourne wrote:

Hi, This is to announce the availability of libclc, an open source, BSD licensed implementation of the library requirements of the OpenCL C programming language, as specified by the OpenCL 1.1 Specification. libclc is intended to be used with Clang's OpenCL frontend. libclc website: http://www.pcc.me.uk/~peter/libclc/ libclc is designed to be portable and extensible. To this end, it
