# Progress #

* TCWG-332, [1/10], patch is posted for review.
* TCWG-187, [1/10], looks like a kernel (~3.4) bug on setting VFP
registers through ptrace. Fails go away after I upgrade the kernel.
* TCWG-387, [2/10], binutils patch is committed, while GDB
patches are being reviewed.
* TCWG-422, [3/10], Read AAPCS and gcc source code to understand the
calling convention. On going.

* FSF patch review, [2/10]
** Review patch set "all-stop on top of non-stop for remote".
** Review ARM fast tracepoint patches.
** Reopen PR 15564, as the fail isn't fixed.

* Misc, meeting, [1/10]

# Plan #

* TCWG-422
* Support ST on using AArch64 multi-arch GDB if needed.
* Review ARM GDBserver software single step patch.

- Waiting on feedback from Maxim who is running patch on Linaro
validation

* TCWG-369 - Exploit wide add operations when appropriate for Aarch64 (4/10)

== Progress ==
* Validation
- comparing results and build times between the 2 labs
- tuning jobs scheduling to avoid deadlocks

* GCC trunk monitoring
- lots of validation results to check after 1 week of holidays :-)
- a few regressions/new failures/wrong tests reported

* Backports
- a few reviews

== Next ==
* Infrastructure/Validation
