[Pkg-opencl-devel] Bug#857591: libclc-amdgcn: apply upstream Mesa patch

[Ian Bruce]

Package: libclc-amdgcn
Version: 0.2.0+git20160907-3
Severity: important
Tags: upstream patch

Running the "clinfo" utility (with AMD GPU), from the package of the
same name, produces the following openCL compile error:

    unsupported call to function get_local_size

This is a known problem, and is being widely complained of, as it makes
openCL unusable on AMD GPUs:

Fortunately, a patch is now available from Mesa upstream:

https://bugs.freedesktop.org/show_bug.cgi?id=99856#c24

However, it is suggested that "distros will probably have to apply that
patch individually":

Please do so; until this is done, libclc-amdgcn is effectively unusable.
