I'm not sure if it's possible. I want to study OpenCL in-depth, so I was wondering if there is a tool to disassemble an compiled OpenCL kernel.
For normal x86 executable, I can use objdump to get a disassembly view. Is there a similar tool for OpenCL kernel, yet?
I know that this is an old question, but in case someone comes looking here for disassembling a AMD GPU kernel, you can do the following in linux:
export GPU_DUMP_DEVICE_KERNEL=3
This make any kernel that is compiled on your machine dump the assembled code to a file in the same directory.

The simplest solution, in my experience, is to use clangs OpenCL C compiler and emit SPIR. It even works on Godbolt's compiler explorer: https://godbolt.org/z/_JbXPb
Clang can also emit ptx (https://godbolt.org/z/4ARMqM) and amdhsa (https://godbolt.org/z/TduTZQ), but it may not correspond to the ptx and amdhsa assembly generated by the respective driver at runtime.
