[LEDE-DEV] [PATCH v2] toolchain/arc: update to the most recent release arc-2016.09
Alexey Brodkin

Mon Feb 27 10:27:50 PST 2017
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:

Changes v1 -> v2:
* GCC_USE_GRAPHITE option is restored, only dependency on
!GCC_VERSION_4_8_ARC is now removed.

+I talked to Andrew about what files he changed in GCC and created and
+tested this new patch. Andrew also mentioned changing some assembly
+files in glibc but I don't see any use of '.section .note.GNU-stack' in
+any assembly files in glibc (for any platform) so I wasn't planning on
+creating a glibc to add them to mips glibc assembly language files.
+
+OK to check in this patch?
