Re: [PATCH] add Altivec/VMX state to coredumps

You're probably right :)

What cores have SPE at the moment? Also, perhaps more importantly,
are there any plans to have Altivec and SPE in the same core?

The e500 cores's from Freescale.

No, they are pretty much mutually exclusive.

I've been working with Carlos Eduardo Seo (Cc'ed on this mail) on
the GDB side of this.

 From comments it looks like the expectation is that the combination
of note type and name which is expected to be unique.

I'm wondering if we should handle this via
elf_coredump_extra_notes_size() & elf_coredump_extra_notes_write().
Does GDB care about the order it sees the various sections in?

I don't think those callbacks will work in this case, they're only
called for the primary thread that's doing the coredump, not for each
thread. Perhaps there's a way to adapt it though.

I think the easiest solution for now is just to make the note type a
#define and create a new value for Altivec.

Oh, well.  It shouldn't be too difficult to abstract vector handler  
similar to how we do GPRs today to the core dump code.
