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

* Infrastructure:
- tcwg-buildapp + lava now triggered daily, to check lava/lab reliability.
- updated builder dockerfiles with postfix config. Patch under review
- some progress on enabling use of Linaro binary release on old
distro. My proposal was rejected, but the discussion moved forward.
- fixed toolchain build not to ship 'runtest' anymore, and moved
gdbserver from bin/ to sysroot dir
* misc (conf-calls, meetings, emails, ....)

== Progress ==
* GCC
- FDPIC
- rebased GCC and GDB patches on top of recent master branches.
- adjusted some of the GDB (gdbserver) patches to cope with gcc-8
complaints.
- adjusted CI testsuite to cope with gcc-8
* GCC upstream validation:
- no regression to report this week :-)
- still checking go/libgo random results on some tests
* Infrastructure:
- improved tcwg-buildapp (Using Lava, thanks to Remi). Now retries
lava job several times if needed.
- managed to configure postfix to send emails from our build
containers (thanks Ben). Once this is properly configured/deployed,
we'll finally be able to send GCC validation results to the
appropriate list
- resurrected my old work to force use of the old memcpy version
such that our binary toolchains work on older distros (such as
RHEL6...)
* misc (conf-calls, meetings, emails, ....)
== Next ==
* GCC/FDPIC
* GCC upstream validation
== This Week ==
* Code hoisting (TCWG-1234) (6/10)
- Working on approach to add basic block info to ANTIC sets
* GCC bugs (3/10)
- Extend sincos to handle sin 2x (PR83661): Patch completed.
* Misc (1/10)
- Meetings

classes must be is_trivially_destructible.

[2/5]
Patches v2 are updated and posted.
* Fix one GDB issue with OpenOCD, which is a long standing issue. [1/5]
Patch is tested, but not committed yet.
