Working on testing "glibc" by using --enable-systemtap.
* Experimented with "Cbuildv2" native building.
== Plan ==

- Investigate "PGO" for Aarch64.
- Work on "glibc" probe.
== Issues ==
Waiting for feedback on "libssp" machine descriptions changes.

===
14-Jan-2014 leave.
== Progress ==
* Draft wiki page (under ACL--let me know if you want to see) for
instructions for setting up chroots on chromebooks for glibc testing:
https://collaborate.linaro.org/display/~ryan.arnold@linaro.org/Configuring+…
* Investigated expanding remote testing possibilities in glibc.
* RFC email to libc-alpha discussing proposal for glibc host testsuite
in chroots:
https://sourceware.org/ml/libc-alpha/2014-01/msg00222.html
== Issues ==
* Shortened week (3-days) because of unplanned school closures on
Monday and Tuesday due to freezing temperatures, during which I had to
watch my kids.
== Plan ==
* Start code scaffolding for glibc host testsuite in chroot.
* Start cbuild2 scaffolding for building remote chroots for glibc testing.
* Add glibc multi-lib builds and IFUNC system libraries.
* Work on cbuild2 support for local tar files.
== Progress ==
* Two day week
* Catching up on email etc. after break (0.5/10)
* Investigate setjmp/longjmp SystemTap probe support in ARM glibc
(1/10, TCWG-378)
* Investigate toolchain bug reports for ARM and AArch64 (0.5/10)
== Issues ==
* None
== Plan ==
* Resume QEMU ARMv8 AArch32 work
* Hopefully push glibc ARM pointer encryption fix for 2.19

Toolchain Working Group, Linaro
- 2013.12 releases (1/10)
* Sent announcements for 4.7 and 4.8 releases.
- 2014.01 releases (2/10)
* Created 4.7 and 4.8 branch merge requests (had handle some conflicts in 4.8)
* Looked at backporting the crypto intrinsics support into 4.8, but
there are dependencies with several other patches we haven't
backported yet.
- cross validation (4/10)
* Restarted them since I had to stop them during the holidays. Still
catching up with the backlog, should be OK during the week-end.
* Analyzed and reported several regressions or new tests failing in
some configurations.
- Neon intrinsics tests (1/10)
* Looked at Rob's neon-intrinsics branch and sent him some feedback.
- misc (2/10): conf-calls and meetings.
== Next ==
- 2014.01 releases
- cross-validation: look at results and report regressions if any
- resume libsanitizer work for AArch64
== Progress ==
* Release 3.4 went out
* Buildbots
- Using powered USB hub for the external harddrive, but all boards fail
one time or another...
- Maybe it's the hard-drive type (mobile, power-saving), reverting to USB
sticks for now
- Leaving an odroid U2 running on USB stick for a week, used to work...
- C++11 features will need GCC 4.7+, looking for an easy way to upgrade
the Chromebooks
* MCJIT
- Finished work on remote MCJIT to re-enable the failing tests
- http://llvm-reviews.chandlerc.com/D2527
* Pragma Vectorize
- New discussions hint that my parser patch is moot, for now
- Agreement is to use C++11 attributes for now, and add pragmas later
- I can't continue implementing them, though...
* Background
- Huge number of patch reviews during holidays & this week
- Good progress on new features for the IAS
- More progress on EHABI, including IAS support
* Time
- CARD-862 8/10
- Others 2/10
== Plan ==
* Continue reviewing IAS features, maybe implement some
* Work out how to create a libcxx bot
* re-introduce llvm-chrome-01 as second self-host
* Migrate all buildbots to GCC 4.7+
* Check out EHABI tests and assess progress
