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.c...@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.renne...@embecosm.com>
Brendan Kehoe <bren...@zen.org>
Simon Cook <simon.c...@embecosm.com>
* config.gcc (arc*-*-elf*, arc*-*-linux-uclibc*): New configurations.
libstdc++-v3:
2012-08-16 Joern Rennecke <joern.renne...@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.renne...@embecosm.com>
* config-list.mk: Add arc configurations.
