# Progress #
* TCWG-333, Fix gdb.base/func-ptrs.exp fails in thumb mode. [4/10]
Finish the patch, tested it on arm and ppc64. Post patches for
review.
* TCWG-556, aarch32 GDB buildbot slave. In progress. [1/10]
Sergio needs to adjust buildbot setting to customize my buildslave.
* TCWG-547, [2/10]
Ping the patch series, and commit some obvious ones.
* Misc, [3/10]
** Ask two people about using OpenOCD with AArch64 board.
** Review kernel patch to fix kernel limitation of byte address select.
Patches look good, but GDB needs to detect that such limitation is
removed.
** Read "C++ Primer". Need more knowledge on C++.

* 3 days off
* Connect week
== Progress ==
* Validation
- patch reviews (jenkins jobs, abe)
* GCC
- reported a few regressions on trunk, helped validating fixes
- ran benchmarks with "deprecated IT blocks" patch.
A few regressions, need to reproduce on other HW
* Binutils
- fixed https://sourceware.org/bugzilla/show_bug.cgi?id=20608
"Relocation truncated to fit: R_ARM_THM_JUMP24 for relocation to PLT entry"
- requested backport approval for branches 2.26 and 2.27, but
no answer so far
* misc (conf-calls, meetings, emails, ....)
== Next ==
* (try to) handle backlog of GCC trunk regressions
* ABE patches reviews and bug fixes
* backports/reviews
* GCC: run benchmarks on other HW
o Two days off post-connect (4/10)
== Progress ==
o Linaro GCC/Validation (3/10)
- Restart work on 4.9.4 branch merge.
- Restart backport activity.
- Investigate binary release size issue (Lin. bug #2544)
o Misc (3/10)
* Various meetings and discussions.
* Reviewing release tools branch
== Plan ==
o Continue on-going tasks (backports, 4.9.4 merge, release tools)
o ABE bugzillas
== This Week ==
* TCWG-807 (2/10)
- Upstream patch iterations with Honza and Martin.
- Committed to trunk as r240898.
* TCWG-779 (1/10)
- Changed %Z specifier to take int*, unsigned len args instead of vec<int>
for easier format checking.
- Committed diagnostic.c and diagnostic-core.h changes.
- Waiting for approval for other parts of the patch.
* Misc (1/10)
- Committed patch to fix typo in bits propagation
- Committed patch for freeing m_vr and bits in ipcp_transform_function
* Holidays (6/10)
== Next Week ==
- Abe bug 1439
- Extend tcwg-buildapp to include SPEC2000
- Address reviews for TCWG-779
- Look at checked exceptions nothrow propagation.
- TCWG-319
== Activity ==
- AFDS and AFDS review comments
LLD:
- Have nudged the ARM exceptions story in lld along a bit, I've had
one patch accepted, but not the most important one.
- Updated the Linaro TCWG jira issues post Connect
- Worked on static linking and ifunc support. I have managed to get
ifunc working for dynamic linking and static linking working for an
old ARM only sysroot. The latest Linaro linux-gnueabi-hf sadly
segfaults in __libc_init_first -> __ctype_init, with what looks like
stack corruption of the return address. I at least have a good idea of
what needs to be done to make static linking work.
Other LLVM:
Some upstream review comments for ILP32 support and others.
== Plans ==
On holiday all week. Will attempt to continue upstreaming lld work
that I already have patches and tests for.
# Progress #
* TCWG-333, Fix gdb.base/func-ptrs.exp fails in thumb mode.
[3/10] Recall some discussions on it in GNU Cauldron, and
dig into GDB source. Unfortunately, GDB decides to track
function address rather than function pointer in 2001, which
makes harder to fix it. Still thinking about it.
* TCWG-556, aarch32 GDB buildbot slave. [2/10]
Build GDB and test cases in arm on an aarch64 machine. There are
1000+ test fails, but not triaged yet. Discussed upstream on how to
set up buildbot slave with special configuration option and test
board file. Ongoing.
* TCWG-685, GDB 7.12 release, and patches review. [1/10].
All blocking issues are gone. 7.12 should be released soon.
* Clean up arm xml files. Done. [3/10]
* Misc, meetings. [1/10]
# Plan #
* TCWG-333, TCWG-556.
* As 7.12 goes out, ping my pending patches on TCWG-518, and TCWG-547

== Progress ==
* [Lab] ASAN test fails with glibc 2.23 [TCWG-811]
- Recommitted upstream after discussing with Adhemerval at Connect
(thanks, Adhemerval)
- The bot is now upstream
* Add worktree module to tcwg-release-tools [TCWG-783]
- In review. Trying to use it in our llvm-projs helper script
* Investigate buildbot failure on clang-native-arm-lnt [TCWG-832]
- Found and reverted the offending patch
- Ran a pre-commit test on the second version of the patch
* [Lab] Xenial Stage1 test failure: std::length_error [TCWG-821]
- Couldn't use gdb on this, so I had to manually find the call that
throws the exception; the code seems to be doing the right thing, and
in addition selfhosting works, so we're suspecting either some
undefined behaviour or a bug in the g++ toolchain on the bot
- Neither ubsan nor clang-tidy had much to complain about the code,
so this will require more investigation
* Misc
- Upstream code reviews, meetings etc
== Plan ==
* [Lab] Xenial Stage1 test failure: std::length_error [TCWG-821]
* [ARM] Switch from itineraries to schedule models [TCWG-824]
