Which registers are available to talk to is a property of the target;
you might want to look at target descriptions, which have been my
project for the last year or two.  Which ones a DWARF number refers to
are a gdbarch property.

No, I mean, you use the OSABI setting to determine which set of dwarf
registers you mean.  I don't know what you meant by "another
difference is the OSABI setting"; you should not be setting the OSABI
in your arc_gdbarch_init, you should be using the normal sniffers and
letting gdbarch_init_osabi dispatch appropriately.
