Hi Christophe,
Here are the commits, in order, that Adhemerval did to support 48-bit
VMA on AArch64.
r275792: [asan] Enable 48-bit VMA support on aarch64
r277137: tsan: Enable 48-bit VMA support on aarch64
r279752: msan: Enable 48-bit VMA support on aarch64
r279753: dfsan: Enable 48-bit VMA support on aarch64
Currently, all sanitiser tests pass on Ubuntu Xenial on the LLVM side.
cheers,

== Progress ==
LTO/IPA
- Committed ipa-vrp and early-vrp improvements
- Patches for propagation of nonnull and optimization are accepted;
Will commit after testing (once again)
- Noticed some improvements but full benchmarking not yet done
- Setting up the benchmarking infrastructure
== Next ==
- Commit pending patches
- Start LTO benchmarking and analysis
== Progress ==
o Linaro GCC/Validation (7/10)
- Completed backports for monthly snapshots (dependency tracking).
- Prepared branch merges for branches 5 and 6
- ABE reviews
- New jenkins job to compare toolchains
(goal is to use it for development and to refactor current jobs).
o Misc (3/10)
* Various meetings and discussions.
== Plan ==
o Release 2016.10 snapshots
o On Vacation from Thu 20th to Tue. 24th.
== This Week ==
* TCWG-72 (3/10)
- Committed patch to remove optab functions for [us]divmod_optab after
Bernd's approval.
- My assumption that __udivmoddi4 is generically available is perhaps
wrong, call to __udivmoddi4
generates undefined reference error on aarch64-linux-gnu. To be
safe, I dropped generating call
to __udivmoddi4.
- Patch posted upstream
* TCWG-834 / PR71636 (1/10):
- Patch posted upstream.
* Misc (2/10)
- PR35503: Changes to C++FE approved by Jason, waiting for approval to
C, C-family changes.
- Posted patch upstream to add reverse keyword to genmatch
- Posted patch for abe bug 1439
- Meetings
* Public Holidays (4/10)
== Next Week ==
- TCWG-72, TCWG-665, TCWG-319
- Add support to tcwg-buildapp for SPEC2000 and SPEC2006.
== Progress ==
* Test GlobalISel on AArch64 Linux [TCWG-825]
- Got the existing tests to work on Linux - luckily this only required
changes to the tests and not to GlobalISel itself; committed these changes
upstream
- Ran the test-suite with GlobalISel and with the fallback to the old DAG
ISel enabled; only 57 object files can be compiled with GlobalISel only,
the others need the fallback to the old ISel; also, there are crashes in
over 500 of the tests
* Rewrite llvm-projs in Python [TCWG-833]
- Rewrote the core functionality of the script and added tests
- Still have to implement the command line interface
* Handle special cases in AArch64InstrInfo::GetInstSizeInBytes [TCWG-757]
- Committed upstream
* [AArch64] CMP + label arithmetic not supported [TCWG-710]
- Committed upstream
* Misc
- Upstream code review
- Linaro annual performance review
- Had a quick look at a hanging check-all in one of the AArch64
buildbots; I identified the hanging test as one of the TSAN tests, but I
didn't manage to reproduce the issue locally (since the tests run in
parallel, it's possible that there's a subtle interaction between them);
I've seen other buildbots (PowerPC) similarly hanging every now and then,
but I'm not sure it's the same issue; will keep an eye on it though.
== Plan ==
* 2 weeks off
# 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++.
# Plan #
* Other thing on OpenOCD,
* TCWG-167, TCWG-416,
