# 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.

* GDB 8.1 release. Fix regressions.

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.

For an explanation of the changes please see the following website:
https://gcc.gnu.org/gcc-7/changes.html

[1]. Source package snapshots are defined when the compiler is only
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.

== Progress ==
o Linaro GCC/Validation
* GCC 6.4 and 7.2 binary releases deployed
* 2017.11 snapshots:
- 6.4 and 7.2 ready to be deployed
o LLVM ramp-up
* Upstream BZ 32999:
- Struggled to construct the testcases which
produce the DAGs needed for a good coverage
- Re-working sub-vectors indexes logic to handle
these testcases.
o Misc
* Various meetings and discussions.
# Progress #
* TCWG-1040, [6/10]
Update my patches to remove the last use of MAX_REGISTER_SIZE.
Post the whole patch series as an RFC. There are 15 patches, but I
rewrote them in seven times. This version is quite satisfying.
Targeting to GDB 8.2. One patch can't be merged until 8.1 is
branched.
* TCWG-1125, ARMv8 tagged address support in GDB.
Writing v3. [2/10]
* Misc, [2/10]
# Plan #
* TCWG-1125,
