Hi Arpith, That is exactly what it is :). My bad, I thought I copied over the libraries to where LIBRARY_PATH pointing but apparently it was copied to a wrong destination. Thanks a lot.

Hi, I wanted to ask whether there is ongoing effort (or an already established tool) that enables to convert CUDA kernels (that uses CUDA specific intrinsics, e.g., threadId.x, __syncthreads(), ...) to LLVM IR. I am aware that I can do this for OpenCL with the help of libclc but I can not find something similar for CUDA. Thanks -------------- next part -------------- An HTML attachment was

Hi, My goal is to use Clang/LLVM/libclc to compile an OpenCL kernel and eventually generate a PTX code. I already did this but I am not sure if the PTX code I am generating is correct (is the one that is supposed to be generated). For example, currently, In OpenCL : get_global_id(0) translates to In LLVM : %call = tail call i32 @get_global_id(i32 0) which translates to In PTX:

Hi, I was wondering if there is a paper or a technical report that documents the performance impact of the different optimizations passes on a some set of benchmarks. Is something like this available ? Best regards, Ahmed -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I get this error when compiling a code that contains "__sync_synchronize()" fatal error: error in backend: Cannot select: 0x85ddfb0: ch = AtomicFence 0x85fd8d8, 0x85c7890, 0x85dd9e8 [ORD=4] [ID=27]example.c:378:13 0x85c7890: i64 = Constant<7> [ID=5]example.c:378:13 0x85dd9e8: i64 = Constant<1> [ID=6]example.c:378:13 I believe it should be equivalent to
