* TCWG-181 - Bench marking core mark with LTO (2/10)
Measuring -O3 -flto vs -O3 on Aarch64 machine with Linaro GCC and
Trunk FSF GCC.
* TCWG-520 ICE in linaro compiler for ARMv7 target (4/10).

* Cbuildv2 preparation for hack session in LCU14.
== Progress ==
* Regression on alphaev68-linux-gnu due to uxt/sxt commit (7/10)
- built cross alphaev68-linux-gnu and reproduces it with qemu.
- Issue is due to PROMOTE_MODE definition and VRP truncating values.
- discussed upstream and after a failed patch, it was suggested that
the value ranges have to be calculated in promoted_mode precision.
- Patch to do VRP in promoted_mode is in testing. There are few
failures to fix.
- An easier fix probably is to check the promoted mode against
word_mode and disable uxt/sxt elimination.
* TCWG-521 - Analysed Coremark and Spec2k for uxt/sxt optimizations
TCWG-521(2/10)
- Continue with Coremark and have additional patches in development for
missing cases.
* bswap pr43550 (No card yet) (1/10)
- Finished regression testing. Will post the patch after resolving
regression with alpha.
== Paln ==
* Continue with VRP in promoted mode, TCWG-521 and bswap pr43550.
== Issues ==
* Multiple validation infrastructure issues (gerrit/jenkins/git.linaro.org)
now fixed.
* aarch64-none-elf is now really long to complete (~11hrs) whereas it
