%description
Clspv is a prototype compiler for a subset of OpenCL C to Vulkan compute
shaders.

It consists of:

- A set of LLVM Module passes to transform a dialect of LLVM IR into a SPIR-V
  module containing Vulkan compute shaders.
- A command line compiler tool called 'clspv' to compile a subset of OpenCL C
  into a Vulkan compute shader.
