Gallium3D / LLVMpipe With LLVM 2.8

Gallium3D / LLVMpipe With LLVM 2.8: While LLVM 2.8 was just released, we have been curious to see how the latest Low-Level Virtual Machine compiler code affects the performance of the LLVMpipe driver. This is the Gallium3D graphics driver that lives in Mesa and leverages the unique modular LLVM compiler to efficiently handle processing the graphics rendering workload on a modern CPU as a much faster alternative to that of their legacy software rasterizer. To see how much of a performance impact - for better or worse - that LLVM 2.8 has on this open-source software driver we tested it when being built with LLVM 2.6, 2.7, and the 2.8 SVN code.
