Since I posted the port the last time, there have been a number of changes as well in GCC trunk as in the port, so a new patch set is required to build the port in trunk. Sanity-checked by bootstrapping i686-pc-linux-gnu. OK to apply? 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.
