This part is broken, it needs to be indented with spaces instead of tabs.

Please drop this change, it is unnecessary.

[OpenWrt-Devel] [PATCH 1/2 v3] 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

Changes compared to v2:
 * Rebased on top of the current master.
   In particular that commit touches uClibc files:
   
http://git.openwrt.org/?p=openwrt.git;a=commit;h=b70a36d1d969f5aa9ad081c9a395633793582a5a

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
