whats the status of debugging nvptx targets?

I know nothing about debugging CUDA devices so I can't provide you with any status. However, I assume that whatever works with C CUDA programs should work with Rust CUDA programs.

If we are talking about debugging CUDA host programs then GDB and LLDB should be very well supported. Debugging a Rust CUDA program should be no different than debugging a normal Rust program.

is there any plans to support radeon graphicscards?

@BadFactor Radeon graphic cards don't run PTX code (AFAIK) so they are outside of scope for this repository. Long time ago someone was working on enabling the LLVM backend that emits the AMD counterpart of PTX but, AFAIK, they didn't arrive at something functional. You can see their work in this PR. That means that rustc, itself, cannot emit PTX-like code for AMD cards so that would need to be fixed first.
