> Let's remove it.
Two things to consider:
. Regardless of whether someone votes to remove an option, a segfault
should always be analyzed. It's easy enough to otherwise just hide
an error that will only reappear later on.
. As long as the AVR backend has a substantial number of PRs open about
"missed optimization", related to [u]int8_t -> int promotions, the
-mint8 option should stay, as it appears to be useful in particular
to people using very small controllers (ATtiny13, also think about
the new ATtiny4/5/6/9 series). Non-applicability of this option to
avr-libc is not a serious issue for those targets anyway, so this
(counter-)argument doesn't count here.
