What do you mean by "a set of gdb"?

Cuda-gdb and ROCgdb are two separate forks of GDB, made to debug Cuda
and ROCm programs respectively.  They are not interchangeable, as they
are both designed to debug programs running on their respective
platforms.  They currently both reside outside of the upstream GDB tree.
I can't speak for Nvidia, but AMD intends on (and is actively working
on) contributing ROCgdb to upstream gdb.  So in some not too distant
future, it should be possible to debug ROCm programs with an upstream
GDB build.

I am not sure what kind of differences between the two you are after, so
feel free to ask further questions.
