The Khronos Group today announced the ratification and public release of the SPIR 1.2 specification that provides a non-source encoding, and binary level portability, for OpenCL 1.2 device programs. SPIR (Standard Portable Intermediate Representation) is the industry's first open, cross-platform Intermediate Representation standard for portable heterogeneous parallel computing and is based on LLVM IR. SPIR enables developers to avoid exposing sensitive kernel source and enables a diversity of language front-ends to easily target OpenCL platforms and devices in addition to OpenCL C. The SPIR specification and registry can be found on the Khronos website.
Stop by the Khronos booth at HiPEAC on 21st Jan for the latest updates on SPIR and discussion on compiler technology for parallel computation.
The Khronos Group recently launched the SPIR 1.0 specification for OpenCL. The specification defines version 1.0 of the OpenCL Standard Portable Intermediate Representation (SPIR). SPIR is a mapping from the OpenCL C programming language into LLVM IR.
