Nothing to get excited about.
OpenCL == JITted C code.
How many c99 compiler do you know that can jit C code?
Its been open secret for long time in fact first entry of opencl in wikipedia
mentioned clang/llvm but was removed after sometime. Intel podcast mentioned it.
gcc mailing list pondered it. etc...
Apple has used LLVM to jit OpenGL. so it is natural progression with OpenCL.
In fact why do you think all the interpreted languages are jumping to
using LLVM. free JIT and multicore support.
