Re: Xtensa port
Thanks for your comment, Michael,
I think I need to look closely at the "multi-arch" mechanism and see if
it's adequate to Xtensa configurability.

Michael,
Thanks much for the quick response.
At a quick first glance, it looks pretty good.
Do you have a copyright assignment on file
Once in a while, Daniel Jacobowitz mentioned that he has all the
necessary paper work for Xtensa port. I hope it still true.
One question -- is there a reason for splitting xtensa-config.c
into a separate file? Not necessarily a problem, but it seems
to be mostly stuff that would traditionally go in the xxx-tdep.c
file (such as the struct gdbarch_tdep object).
It's because Xtensa is all about configurability. Historically,
Tensilica uses a special configuration called FSF for all our FSF
submissions. It's been used for Xtensa GCC and BFD work. Now, I'm trying
to use it for GDB. So when we have to deal with a different
configuration of the Xtensa processor all we need is to update
xtensa-config.c file.
Ah, but that's what we have a thing called multi-arch for!
Wouldn't you rather have a single gdb that could debug *any*
of your xtensa configurations (as opposed to having to build
a separate gdb for each one)?
