I might be missing some relevant context here, but have you looked at how the AMDGPUStructurizeCFG pass is added in R600/AMDGPUTargetMachine.cpp? -Hal > > > > _______________________________________________ > LLVM Developers mailing list > LLVMdev at cs.uiuc.edu http://llvm.cs.uiuc.edu > http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev >

...on of the backend: The r600 backend is being developed as a part of the Open Source compute stack in Mesa (http://www.mesa3d.org/), which uses the Gallium API. It uses large portions of the AMDIL backend which was open-sourced last December and you'll notice the TargetMachine for this backend (AMDGPUTargetMachine) is a sub-class of AMDILTargetMachine. We are also currently working on an LLVM backend for Southern Islands GPUs, and we would like to get that code into the LLVM tree as well, once it has been approved for release. The Southern Islands backend will be used for compute shaders and also graphics...

Hi, I've prepared patches for both LLVM and Clang to change the datalayout for R600. This may seem like a bold move, but I think it is warranted. R600/SI is a strange architecture in that it uses 64bit pointers but does not support 64 bit arithmetic except for load/store operations that roughly map onto getelementptr. The current datalayout for r600 includes n32:64, which is odd

Hi all, I'm looking into the performance difference of a benchmark compiled with NVCC vs NVPTX (coming from Julia, not CUDA C) and I'm seeing a significant difference due to PTX instruction ordering. The relevant source code consists of two nested loops that get fully unrolled, doing some basic arithmetic with values loaded from shared memory: > #define BLOCK_SIZE 16 > >
