Configuration bits for ARC port:

toplevel:

2013-02-25  Simon Cook  <simon.cook@embecosm.com>

        Changes to build configuration to allow big endian ARC ELF toolchain
        * configure.ac: Also add target-libgloss to noconfigdirs for arceb-*-*.
        * configure: Regenerate.

gcc:

2013-04-03  Joern Rennecke  <joern.rennecke@embecosm.com>
            Brendan Kehoe  <brendan@zen.org>
            Simon Cook  <simon.cook@embecosm.com>

         * config.gcc (arc*-*-elf*, arc*-*-linux-uclibc*): New configurations.

libstdc++-v3:

2012-08-16  Joern Rennecke  <joern.rennecke@embecosm.com>

        * acinclude.m4 (GLIBCXX_ENABLE_SJLJ_EXCEPTIONS): Also check for
        _Unwind_SjLj_Register when deciding if to set enable_sjlj_exceptions.
        * configure: Regenerate.

contrib:

2013-09-05  Joern Rennecke  <joern.rennecke@embecosm.com>

        * config-list.mk: Add arc configurations.
