4.3 is also broken. Using the simpler test case in PR43732 and a collection of
cross-compilers to mips-unknown-linux I see:
gcc-4.1.2: -O2 only: ok; -O2 -ffixed-23: ok
gcc-4.2.4: -O2 only: ok; -O2 -ffixed-23: ok

Isn't this just a user error then? You should have used -ffixed-20 if you use
a call saved register as global register IMHO.

Well -ffixed-reg-r20 is also broken the same way :) See the duplicated bug
which has a patch which I have not looked into to see if it is the correct fix
yet or not.
