I have maintained unwind support for FreeBSD i386 and x86_64 in my
"gnat-aux" repository for many years (I created it). I've always
intended on contributing it back to GCC, but I never got around to
"proving" it worked until now.
The version I've been using actually has two flavors: FreeBSD 8 and
below and FreeBSD 9 and above. However, the last of the FreeBSD 8
releases reaches EOL at the end of June so the unwind support I've
attached here drops the FreeBSD 8 variation for simplicity's sake.
I was under the impression that MD unwinding was used for more than just
GNAT but it looks like that impression was wrong. When I ran the
testsuite, the only tests affected were Ada tests.
It is, libjava uses it.
Note that I provided a similar unwind support for DragonFly a few months
ago. Please consider applying the attached patch to gcc trunk. (copy
