Package: oclminify
oclminifyis anOpenCL™source
minifier. It takes OpenCL source code and makes it as small as possible
by stripping comments, removing unnecessary space, renaming symbols,
rewriting vector indices, etc. The minified source can be optionally
compressed and then saved as is or as a C header. The latter makes it
very easy to embed into a compiled application. The original source and
the minified source are functionally identical and should compile into
the exact same byte code.If you’re targeting platforms with OpenCL 2.0 or later support, you
should consider usingSPIR™instead.oclminify was originally developed by thePhoduitteam.PrerequisitesPython®>= 2.7 (Python 3 is also

with an actual OpenCL driver, install pyopencl with:pip install pyopenclUsageoclminify [-h] [--preprocessor-command PREPROCESSOR_COMMAND]

          inputoclminify takes a single input file. If the input file is - (a single
hyphen), input will be read from STDIN. If the –output-file option is
omitted, the output is written to STDOUT.The available options are:-h, --help            show this help message and exit
--preprocessor-command PREPROCESSOR_COMMAND
                      Command to preprocess input source before
                      minification. Defaults to "gcc -E -undef -P -std=c99
                      -"
--preprocessor-no-stdin
                      Pass input to preprocessor using a temporary file
                      instead of stdin.
--no-preprocess       Skip preprocessing step. Implies --no-minify.
--no-minify           Skip minification step. Useful when debugging.
--compress            Compress output using zlib.
--strip-zlib-header   Strips the two byte zlib header from the compressed
                      output when --compress is used.
--header              Embed output in a C header file.
--header-function-args
                      Include function argument mappings in C header file.
--minify-kernel-names
                      Replace kernel function names with shorter names.
--global-postfix GLOBAL_POSTFIX
                      Postfix appended to each symbol name in the global
                      scope. Used for preventing name collisions when
                      minifying multiple source files separately. Implies
                      --minify-kernel-names.
--try-build           Try to build the input using an OpenCL compiler before
                      minifying. The compiled output is discarded. Requires
                      pyopencl.
--output-file OUTPUT_FILE
                      File path where output should be saved. Omit to write
                      to stdout.ExamplesTo simply minify an OpenCL source file and write the result to file,
run:oclminify --output-file output.minified.cl input.clThe examples directory contains more examples:examples/minimal— shows how to create a minimal project that
minifies an OpenCL source file and builds a C based project using a
shell script.examples/cmake— shows how to integrate oclminify with aCMakebased C++ project.examples/compress— shows how to use oclminify in a CMake project
to compress an OpenCL source file at compile time and then decompress
it at run time.LegalOpenCL is a trademark of Apple Inc., under license by Khronos.SPIR is a trademark of the Khronos Group Inc.Python is a registered trademark of the Python Software Foundation.Copyright (c) 2016 StarByte Software, Inc. All rights reserved.
