-To run the conformance tests you need SPIR-V binaries.
-
-If you are using a conformance package then the binaries are included in the
-package. If you are using conformance tests from gitlab repositories then the
-binaries need to be picked up from Khronos SVN URL mentioned below:
-
-https://cvs.khronos.org/svn/repos/OpenCL/trunk/Khronos/spirv/spirv10_2015.11.25.zip

-Alternatively you can check out and build all of the below repositories.
-

-LLVM with support for SPIR-V (required by clang compiler)
-Repository: https://gitlab.khronos.org/opencl/SPIRV-LLVM
-Branch: spec_constants 
-Notes: spirv-3.6.1 is a main branch with support for OpenCL C++ kernel language,
-  spec_constants is based on it, but it adds support for specialization constants.
