[Buildroot] [PATCH v4 00/11] llvm for mesa3d

[Valentin Korenblit]

Hello all,

This series provides llvm support for Mesa 3D:


Changes v1 -> v2:

The series has been simplified:

*Build only backend for target architecture by default.
*Support for AMDGPU(PATCH 3/4 in v1) was removed because I cannot test
it currently. 
*Host: make options modified to build only llvm-config and llvm-tblgen
(reduces drastically build time for host).
*Target: support only x86 currently (tested), I will test on ARM soon.

Changes v2 -> v3:

* Full installation of LLVM (tools and libLLVM.so) for the host.
* Disable Mesa 3D static linking, it now links with shared lib.
* Options to disable building each tool one by one were removed.
* Support for AMDGPU.
* Support for ARM and AArch64.
*-DLLVM_HOST_TRIPLE=$(GNU_TARGET_NAME) added. This fixes the error:
"No available targets are compatible with this triple" for llvmpipe.

Changes v3 -> v4:

This series is focused on OpenCL support

* Add Clang for host (needed to build libclc)
* Add Clang for target (libOpenCL needs libclang and libLLVM)
* Add libclc
* Add OpenCL support in Mesa3D
* Add package clinfo

Regards,

Valentín
