Is there an OS-independent way to transpile OpenCL kernels into SPIR-V?
Yes, there is an OS-independent way to transpile OpenCL kernels into SPIR-V (Standard Portable Intermediate Representation). You can use the Khronos Group's official SPIR-V Tools library, which provides a command-line tool called spirv-tools
that can convert OpenCL C code to SPIR-V.
Here are the general steps to transpile OpenCL kernels into SPIR-V using the SPIR-V Tools library:
Install the SPIR-V Tools library: Download and install the SPIR-V Tools library from the official Khronos Group GitHub repository: https://github.com/KhronosGroup/SPIRV-Tools
Write your OpenCL kernel code: Create or obtain the OpenCL kernel code that you want to transpile to SPIR-V. Save the code in a file with the
.cl
extension.Use
spirv-tools
to transpile OpenCL to SPIR-V: Open a command prompt or terminal and run the following command:cssspirv-tools --target-env opencl --target-env-version <version> -o output.spv input.cl
Replace
<version>
with the desired OpenCL version (e.g.,1.2
,2.0
) andoutput.spv
with the desired output file name for the generated SPIR-V code.input.cl
should be replaced with the path to your OpenCL kernel file.This command will transpile the OpenCL kernel code to SPIR-V and save it in the specified output file.
The spirv-tools
command-line tool provided by the SPIR-V Tools library is available on multiple platforms, including Windows, macOS, and Linux, making it OS-independent for transpiling OpenCL kernels into SPIR-V.
