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

Progress:
* VIRT-65 [QEMU upstream maintainership]
- more work on rST doc conversion. I've started in on converting the
documentation that we auto-generate from doc comments in json files
(this covers QEMU's QMP protocol and a similar protocol for the
guest-agent).
I now have something that is basically the right shape and correctly
handles 'Command' and 'Object' (with 'Enum' and Alternate' and some
other corner cases still to do). Might be able to send a patchset out
next week with luck. This is I think the last major obstacle to the
rST conversion -- once it's done the rest is just simple-but-tedious
conversion of the remaining document files.
- code review:
+ aspeed 'misc fixes and extensions' patchset
+ "Stop wrongly programming GICR_PENDBASER.PTZ bit" bugfix patch
+ KVM 'adjust virtual time when VM starts/stops' patchset
+ last few unreviewed patches in RTH's VHE patchset respin

== Progress ==
* BFD Linker:
- GNU-629: non-contiguous memory support: fixed bugs found when
running the testsuite with the new option activated. Adding warnings
to help understand potential placement changes.
* GCC:
* GCC-9: continued work for validation of -mpure-code on v6m: the
patch applies cleanly in the branch, but there are unexpected failures
compared to trunk. Debugging.
* GCC upstream validation:
- reported a couple of failures/regressions
* misc:
- infra fixes / troubleshooting / reviews
== Next ==
* Binutils: GNU-629: support non-contiguous memory regions in linker
* GCC-9: continue work for validation of -mpure-code on v6m
== Progress ==
* Updating lldb for the latest Morello architecture changes
* Started running the tests for llvm 10.0.0-rc1
== Plan ==
* Check up on the release
* More Morello

Fixed interworking problem causing Thumb2 kernel not to
Some diagnosis of LLD problem when .ctor and .init_array initialisers are used.
[LLVM-MC]
Upstream reviews for some methods to avoid llvm-mc making symbols
inter-positionable that the code generator has assumed are not.

Clean up my Jira tickets so that they can be passed on or closed.
This is my last week as a Linaro assignee, will be going back to the
Arm as of next week. I've really enjoyed my time here, thank you for
having me.
Buildbots, busy week that took up most of spare time
- deploying timezone fix to containers
- a couple of weekend patches that broke Arm and AArch64 bisected and
followed up.
- difficult to track down stage-2 failure that was difficult to work
out whether there was a bug in clang, or a code-gen failure in the
backend, also made it harder to bisect. Turned out that it had caused
more easy to bisect failures in other projects and by the time I'd
found the patch it had been fixed.
[ClangBuiltLinux]
LLD's simplified interworking looks to be insufficient for the linux
kernel thumb-2 build. Got agreement with upstream on how to proceed.
Have a patch ready to send upstream.
A small amount of upstream review and bisecting some Linaro CI build
failure for the -fpatchable-functions feature in Clang-10. Looks to
have been resolved.
[VIRT-327 # Richard's upstream QEMU work ]
* tcg patch queue flush, including some VHE prereqs.
* target/hppa patch queue flushing.
* combined the two in-flight avr patch sets, hoping
to move that project to completion.
* patch review.
* target/s390x local variable "leak" fix,
to satisfy a static analyzer.
[VIRT-263 # ARMv8.1-VHE Virtual Host Extensions ]
* started rebasing, and addressing the collected
comments from v4 in December.

Progress:
* VIRT-65 [QEMU upstream maintainership]
- code review:
+ RTH's bug fix for the PAuth ComputePAC operation
+ patchset adding DMA support for Exynos4210 UARTs
- small patchset documenting the right way to conditionally run
expensive computations that are only needed for trace event output,
and updating a handful of places that used an older (worse) method
- more QEMU documentation conversion to rST; in particular wrote a
Sphinx 'hxtool' extension to handle pulling out fragments of documentation
from QEMU's '.hx' files which define and document command line options
