This patch will have to be rebased, since I just made some changes to
get rid of the old uClibc version. I also removed version configuration,
and the version suffix of the config directory.

Thanks for letting me know.
I'll do this shortly.

In the meantime would be good if people comments on this v2 series so I may do 
required
changes in v3 as well.

[OpenWrt-Devel] [PATCH 1/2 v2] toolchain: add support of ARC architecture

2015-11-02 Thread Alexey Brodkin 
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
Makefile:699: recipe for target 'stamp-5mloop' failed
make[7]: *** [stamp-5mloop] Error 1
>8

Prerequisites are:
 [1] http://patchwork.ozlabs.org/patch/539068/ which bumps uClibc-ng version
 from 1.0.6 to 1.0.8
 [2] http://patchwork.ozlabs.org/patch/502022 which updates config.guess
 and config.sub

Changes compared to v1:
 * Binutils Kconfig description is now similar to Gcc and uClibc.
   This allows selection of different versions of binutils.

 * CONFIG_BINUTILS_VERSION_2_23_ARC is used for deciding if we need to
   obtain ARC's binutils.

 * Rebased on current master
