Developers from the member companies involved with Linaro are planning continued improvements to the LLVM compiler infrastructure that will benefit ARM developers and customers. With this ARM LLVM work there should also be Gallium3D LLVMpipe enhancements.
Last week at Linaro Connect Asia 2013, aside from talking about OpenGL ES 3.0 improvements, there were also sessions about improving LLVM ARM support.
The Toolchain Working Group started playing with LLVM optimizations and other improvements to this compiler infrastructure in January. They've made some progress so far, but plans were revealed for a lot more.
The LLVM team goals within the Linaro Toolchain Working Group are to improve performance for 32-bit and 64-bit ARM (both AArch32 and AArch64) and supporting the community. The performance work is mostly focused upon back-end work while there's some mid-end work involved too.
