Wait... just yesterday you wrote:
"I do think so too.
I have just written a patch so that gdb unwinds correctly on cortex-m
exceptions, and this of course requires that gdb knows about at least
psp."
Maybe I'm confused. I presumed DWARF was involved in unwinding to some
extent, but if its purely just used for debugging, it might not
require PSP / MSP at all.
In any case PSP / MSP are most definitely used in unwinding.
