Last time I used this (many years ago) it all worked great, with almost all of the glibc test suite passing, including the wild tangle of thread-local storage, thread joins, thrown exceptions, stack unwinding, gdb and signals all happening at the same time. There were only a handful of rare, obscure cases that didn't pass. I know, as I did the work to make this all go.

Sorry for the late response. As Linas mentioned, Mentor maintains the that
set of tools. That latest version that was released can be found here:
https://sourcery.mentor.com/GNUToolchain/release2800
I haven't had a chance to test these tools myself though.
Hope that helps.

gcc-4.6 and a similarly aged binutils. Do they have anything newer, and can
they push it upstream?
