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

1 day off (Friday)
== Progress ==
* GCC
- FDPIC
- debugging crash during program startup (self-relocation), and
linker assert when using -static
* GCC upstream validation:
- reported a couple of regressions, tested a couple of patches for upstream
- incremental improvements for more robustness, and easier
configuration of validations
* Infrastructure:
* misc (conf-calls, meetings, emails, ....)
== Next ==
Holidays until Jan 2nd, 2018
Merry Christmas and happy new year!
# Progress #
* GDB 8.1 release. [2/10]
Triage regressions on aarch64 and arm.
* PR 21698. [3/10]
During the patch review, I doubt the patch fixes an invalid
python use in gdb. The GDB doc is quite unclear on how
that python api should be used. Ask the python api owner to
clarify.
* Misc, [5/10]
Two days travel to Manchester.
# Plan #
* GDB 8.1 release. Fix regressions.

No response, people are busy on release.

The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2017.11
snapshot of Linaro GCC 6 and 7 source packages.
o The GCC 7 series introduced an ABI change for ARM targets by fixing a bug
(present since GCC 5, see link below) that affects conformance to the procedure
call standard (AAPCS). The bug affects some C++ code where class objects are
passed by value to functions and could result in incorrect or inconsistent code
being generated. If the option -Wpsabi is enabled (on by default) the compiler
will emit a diagnostic note for code that might be affected by this ABI change.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77728

put through unit-testing and full validation is not performed.
[2]. Stable source package releases are defined as releases where the
full Linaro Toolchain validation plan is executed.
