Hmm, good question. I could make an argument either way. Every port
has this same problem, but then again only the default
print_registers_info and those with their own print_registers_info
would have to be fixed.
Still, it's nasty that value_of_register can handle user registers but
nothing else can. Maybe frame.c should also?
I've been starting to use user registers more heavily lately, since
pseudo registers have strange problems - they only come from a
regcache, not from a frame.
