Re: [WIP/RFC] MIPS registers overhaul

Unfortunately, it isn't reasonable to use an ABI-specific RDA to debug

work some of the time, but there are various things that won't work. You've just identified one of the problems.


BTW, because of this kind of problem, does it even make sense that
when talking to a mips64 kernel but using an o32 rda (or gdbserver
8-), you'd use a "mips64" protocol?  I.e., why wouldn't it just use
the 32-bit mips protocol, since from you're debugging a 32-bit binary
with a 32-bit debugging daemon...

Ignoring the FP registers, I think it does make sense. o32 code does run on a 64 bit ISA. Who is GDB to decide what the ISA should be.
