portability of OpenCL programs with the kernel compiler and the task run-time,
reducing the need for target-dependent manual optimizations.

pocl uses Clang as an OpenCL C frontend and LLVM for kernel compiler
implementation, and as a portability layer.  Thus, if your desired target has
an LLVM backend, it should be able to get OpenCL support easily by using
pocl.")
