[avr-gcc-list] Does longjmp() work with avr6?


Hi.

Traditionally Avr-libc's longjmp() function uses
the 'eijmp' instruction to make jump (and destroys
EIND register). Does avr6 GCC extension known
about this?

And, in general, what is the status of EIND register?
Is it needed to save/restore in assembler functions?
In inline assembler?

Thanks,
Dmitry.
