Hi all, I have been developping a out-of-tree backend. I would like to integrate it with clang. Note that my backend is rather simple, generates elf32, and I do not need about linux, libary paths, ... Can someone give me a pointer to a readme, an article, or maybe a good (i.e. simple) example ? Note :on a second step, I would like to support inline assembly in C code.. -- Frederic Heitzmann

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
