# 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,

== 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

[Prathamesh Kulkarni]

== 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.
