The patches I posted last week do this for PowerPC, in fact!
But there are places where we can't do it this way - at least not
without bigger changes. For instance, on MIPS the
dwarf2_reg_to_regnum method returns pseudo registers. The numbering
of pseudo registers starts at NUM_REGS, which varies depending on
the OS/ABI and on what target we end up connected to :-(
