clcc is an offline compiler for OpenCL kernels

git clone https://github.com/Maratyszcza/clcc.git
cd clcc
pip install --upgrade .

Active projects:

• Apple ships an offline OpenCL compiler openclc for OS X with XCode. It compiles to portable bitcode for CPUs or GPUs, which is recognized by Apple drivers. Mac Developer library documents how to use it.
• AMD maintains CLOC - OpenCL Offline Compiler for compiling OpenCL kernels to HSAIL and BRIG formats.
• Intel OpenCL SDK contains a KernelBuilder. However, it can not build kernels for devices which are not installed on the host system.
• Mali offline compiler can compile OpenCL shaders for ARM's OpenCL-enabled Mali devices and reports some statistics useful for performance optimization. However, it doesn't let you save the machine code for a kernel.

Unmaintained projects:

• Command line interface to the NVIDIA OpenCL compiler from Leith Bade wraps undocumented interfaces of nVidia OpenCL driver. No updates since 2013.
• CLCC - The OpenCL kernel Compiler from George van Venrooij. No updates since 2012.
• OpenCLcc from Isaac Gelado. No updates since 2011.
• CLC: OpenCL compiler and syntax checker from Matias Holm. No updates since 2010.
