1This directory contains SPIR-V builtin functions used by 2the LLVM module converted from SPIR-V by the SPIR-V/LLVM 3converter. The SPIR-V consumers need to add these builtin 4functions to their runtime library. 5 6For OpenCL, most of the SPIR-V instructions are translated 7to either LLVM instructions or OpenCL builtin function calls 8by the converter. Therefore only a few SPIR-V instructions 9need to be implemented in the runtime.
