Is there a way to emit only the kernel ast on the device side

[malixian]

I have a dpc++ code and want to emit only the device code AST. I use a clang command follows:

clang++ -Xclang -ast-dump -fsycl vector_add.cpp

When executing this command, there will be a lot of AST host code that I don’t need.
So is there any way to generate only the kernel ast?

Tagging @Fznamznon to correct me if I'm wrong, but it looks like -fsycl-device-only is an argument you are looking for, @malixian

I don't think we have a way to do that. Even if -fsycl-device-only is passed - AST will be built and dumped by ast-dump for the whole translation unit including host code.

Yes, you are right, I have tried it.
