Spotted while looking into
<http://gcc.gnu.org/ml/gcc-patches/2011-11/msg02001.html> (and
yes, I fixed the ChangeLog typo before commit) and also
mentioned at <http://gcc.gnu.org/ml/gcc/2011-11/msg00406.html>.
Emulating TLS has nothing to do with exception-handling, nor is
there something that might throw while calling one of its
functions, so no need to pass -fexceptions and thus lower
optimizations (which happens at least for targets with
delayed-slots) or carry around exception tables. Tested cross
to cris-elf, no regressions.
Ok to commit?
