All,
During Connect the suggestion was made that each working group should have
its own IRC Channel for discussions and topics relating to the group in
particular (as opposed to #linaro which is 'generic' Linaro conversations).
Therefore I have just set up #linaro-tcwg on Freenode for the Toolchain
Working Group.
This channel is public and open to anyone who wants to talk with the TCWG
group about anything toolchain related.
Thanks,
Matt

- LLVM+compiler-rt build seems OK, but still unable to run the tests on Juno
* Neon intrinsics tests (3/10)
- continued conversion to GCC testsuite
- fixed checks for Neon QC flags
- patch reviews
* Misc (4/10)
- meetings, conf-calls, emails, ....

* TCWG/LAVA lab interactions working with just a couple hacks
* Jenkins job created (thanks Rob) and beginning to work
Misc - [4/10]
* Included a quick look at Will's single-thread performance patches -
unfortunately, no time to actually do anything with them
=Plan=
Benchmarking storage/automation
Look though Will's single-thread performance patches
Switch to TCWG Junos
Write up/think about where to go next with libm exercising
Test benchmark repeatability
=Absences=
On holiday Monday 22nd Dec to Friday 2nd Jan

QEMU kernel debugging setup [3/10] [TCWG-568]
-- Finally figured out the steps to debug kernel with ARM cortex A9 core.
Kernel debugging to investigate limitation of ARM watchpoint
implementation [2/10] [TCWG-569]
-- Debug kernel code with gdb to investigate problems.
Miscellaneous [1/10]
-- Meetings, Emails etc
-- Wiki updates
Sick Leave [4/10]
== Plan ==
QEMU kernel debugging setup [TCWG-568]
-- Figure out steps to debug kernel with ARM cortex A15 core.
More Kernel debugging to investigate limitation of ARM watchpoint
implementation [TCWG-569]
-- Get A15 core running on QEMU and debug kernel hw debug
implementation on both A9 and A15.
Updates to GDB wiki pages with kernel debugging howto.
I've completed renaming Cbuildv2 to Abe, as well as modifying all the
board files for remote testing to match what the new DNS server is
using. Please stop using the existing cbuild2 repository, as all changes
are now done in the new repository. I'll leave the old repository for a
while, I know there are branches there people depend on. For those, I'm
sorry for the pain (having just gone through that myself), but please
migrate any important branches to the new repository. URLs for that are
here:

* A further round of changes, got an OK
Raised a bug on GCC re questionable generation of pow calls - TCWG-558 [0/10]
* Upstream fixed it really fast
Misc - [2/10]
=Plan=
Switch to TCWG Junos, perhaps start using gprof
Think about where to go next with libm exercising
Look though Will's single-thread performance patches
Test benchmark repeatability
Port benchmarking scripts to ABE repo
Start on storage/automation, if Rob has time
