* TCWG-180 Debugging - LTO bootstrap failure in Aarch64 with GCC 4.9. (4/10)
Completed. Patch that sets same tune parameters solves the bootstrap
compare errors in Branch. Closed the JIRA cards. There are still LTO
IR streaming issues in trunk which needs to tracked down and fixed at
tree level. and no plans of doing that now.
* TCWG-520 ICE in linaro compiler for ARMv7 target. Bisected the
revision in trunk which fixes that. Backported and tested and fixes
tha bug. (4/10)
* Others (2/10)
* Bug migration from launchpad
* Meetings Christophe, Ryan, Maxim and GCC status meeting
* Misc and internal meeting.
* setup LLVM.

* Continue Bug fix (TCWG 520).
* Benchmark Core mark with LTO (TCWG-181).
* Upstream patch review.
== MISC ==
* Local Holiday on 29th August
== Progress ==
* TCWG-413 - Release benchmarking (2/10)
- Analysed all the patches gone into the release for performance impact

TCWG-521(3/10)
- Studied Coremark and have additional patches in development for
missing cases.
* bswap pr43550 (No card yet) (3/10)
