arc-2016.09 is the most recent toolchain for ARC cores and
it is based on top of upstream Binutils 2.27 and GCC 6.2.1.

With updated major version of GCC we copied all GCC 6.x patches
for ARC as well as Bintils 2.27 patches.

Note that toochain sports ARCv4 ABI and so must be used
with 4.8+ Linux kernels. Even though it will build v4.4 kernel
perfectly fine on attempt to run user-space apps they won't
work with older kernel. That said previuosly sent RFC patches with
Linux kernel update are required:

-fno-plt and musl-libc patches already get upstream, then dropped
in GCC 6. Other patches are almost identical compared to GCC 5.4.

This includes binutils, gcc, gdb and uClibc-ng.

Latest release of ARC gcc (as of today it is "arc-2015.06")
is based on upstream gcc 4.8.4.

Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/gcc

Latest release of ARC binutils (as of today it is "arc-2015.06")
is based on upstream binutils 2.23.

Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06

Latest release of ARC GDB (as of today this is "arc-2015.06-gdb")
is based on upstream gdb 7.9.1.

Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06-gdb



Note that for binutils and gdb that come from unified git repository
(which is the case for upstream binutils/gdb today) we need to disable
building of gdb in binutils and binutils in gdb hence in binutils:
------>8------
--disable-sim
--disable-gdb
------>8------

and in gdb:
------>8------
--disable-binutils
--disable-ld
--disable-gas
------>8------

Also in gdb we disable sim because if the following breakage while
building with it:
------------>8------------
/usr/bin/env bash ./../common/genmloop.sh -shell /usr/bin/env bash \
        -mono -fast -pbb -switch sem5-switch.c \
        -cpu a5f -infile ./mloop5.in \
        -outfile-suffix 5
unknown option: bash
