Why do we need to do that? The raw, architecture register
is still 64-bit, right?
Sounds to me that if you want to present a 32-bit pc to the user, then
gdb should handle this, via a pseudo register, similarly to how
x32 sends 64-bit rip, and then gdb shows a 32-bit pc. Mips does
something like this too, to a larger extent, see mips_register_name.
