rtl-expansion bits.

- benchmarking tcwg-310 on cortex-a53, cortex-a57, r1-a12, cortex-a17
- submitted job for INT benchmarks for SPEC2006 for aarch64
* backports (2/10)
- r232688 automated backport build failed for aarch64-linux-gnu on
tcwg-backport-gerrit:
Unrecognized macro 'GERRIT_PATCHSET_REVISION' in '#664-
${GERRIT_PATCHSET_REVISION,length=8}'
Build successful on tcwg-backport-maxim

* ccp (2/10)
- enhancement to hoist stmt thru phi with all constant args
- patch: http://people.linaro.org/~prathamesh.kulkarni/ccp-mov.diff
- rejected by Richard, since PRE handles this case when it's
trivially profitable and phiprop does similar transform. In general,
it's not profitable to have this transform included.
* Public Holiday (2/10)
* Misc (2/10)
- Meetings
- Slides: short & long term activities
== Next Week ==
- PR43721: look at using define_expand instead of hook, add test-cases
and few nits
- tcwg-319 - analyse with perf
- LTO INT benchmarking for arm, aarch64 and x86
- LTO Slides
# Progress #
In general, GDB mainline is in a good state. All known bugs are fixed,
but still have some patches pending for review. The release can be
created after these pending patches are in.
* Fix fail in gdb.base/interrupt-noterm.exp. TCWG-517. Done. [2/10]
* Fix fail in gdb.fortran/vla-value.exp. TCWG-521. Done. [1/10]
* PR 19474. [3/10]
Tried different approaches, but still cause regression.
Fortunately get the right maintainer involved. Will discuss with
him on this bug next week.
* Range stepping doesn't work on arm-linux, which slows down stepping
over a line of source. TCWG-518. [2/10]
* Prepare slides for Linaro Connect. [2/10]
# Plan #
* Off on Mon. to Wed.
* Linaro connect slides.
* Thailand visa.
* Other issues on GDB 7.11 release, if any.

The Linaro Toolchain Working Group is pleased to announce the availability
of the Linaro Stable Binary Toolchain GCC 5.2-2015.11-2 Release Archives.
http://releases.linaro.org/components/toolchain/binaries/5.2-2015.11-2/http://releases.linaro.org/components/toolchain/gcc-linaro/5.2-2015.11-2/
These archives provide cross-toolchain executables (compiler, debugger,
linker, etc.) and shared libraries (libstdc++, libc, etc.) that target ARM
or Aarch64 GNU/Linux and bare-metal environments. The cross-toolchain
binaries execute on a Linux or MS Windows (under mingw32) host
operating-system.
Please evaluate this release-candidate for correctness. Linaro will shortly
spin the Linaro GCC 5.2-2015.11-2 release if this release-candidate passes
stakeholder validation.

Hi!
When using the linaro-4.9-2015.05 toolchain on the Linux master and on Linux stable releases
I am seeing a build issue below when using the allyesconfig. This does not seem to occur on the 5.2 tool chain.
We cannot move to 5.2 tool chain for our releases as they are based on 4.9.

Please advise to how to resolve this issue within the 4.9 Linaro tool chain
