This patch provides libclc, an open source implementation of the library requirements of the OpenCL C programming language, as specified by the OpenCL 1.1 Specification. It is intended to be used with Clover (Mesa3D's OpenCL implementation for AMD GPUs. It needs to be compiled with host-clang, as it generates LLVM IR bitcode files containing device builtin functions for each target. Currently, libclc supports AMDGCN, R600 and NVPTX targets. As OpenCL kernels can be built dynamically on the target using libclang and libLLVM, it is necessary to have clc headers installed on the target. Buildroot removes /usr/include in its target-finalize step, so clc headers are installed to /usr/share/clc.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
