Connect detox [2/10]
ABE benchmarking automation - TCWG-360 [5/10]
* Backport benchmarking
** Harder than expected, have to build the backport into a binary,
then benchmark that binary, passing information between jobs.
** AFAIK I'm blazing the Jenkins-chainging trail for us.
* Release benchmarking
** New LAVA release broke my image (but quickly fixed by the LAVA folks)
** Now seems to be running into issues with Jenkins/builders/an
anonymous job-slayer
* Misc fixes and improvements
** Main highlight being support for building with separated-out sysroot
Misc - [3/10]
=Plan=
Kick off catomics benchmark runs
(Attempt to) close out cache effects on Juno issue
Carry on with Jenkins
=Issues=
* Some of the Jenkins builders seem unreliable
* My lightly hacked version of the BinaryRelease job is unreliable
** Is the BinaryRelease job itself is reliable
* TSAN support for Aarch64 (5/10)
Fixed some kernel size issues in my local working tree. (TCWG-581) .
GCC does not default to -fPIE or -pie. Ran into address layout
issues when I used -fsanitize=thread. Some test cases passed with the
mapping I used for 42 bit VA when -pie and -fPIE are added.
* Bug 869 - Looking at match.pd to remove type promotion in ABS_EXPR (1/10)
* Emails, meetings. (2/10)
* Linaro 1-1 with maxim and Ryan.
* AMD meetings/event, 1-1 with AMD manager, status meeting.

- Renato committed my patches to enable ASAN in LLVM/AArch64
- the official aarch64 buildbot (Juno) had problems after these, so
the asan tests are disabled again until the problem is understood.
Probable board configuration problem, since the tests passed on our
Juno.

Hi,
We've noticed that in the 14.11 toolchain binary release that the .asc files
contain md5sums instead of PGP signatures. Would it be possible to either
switch these files to contain signatures or change the filename to indicate
that they contain md5sums?
I also noticed that an md5sum is missing:
http://releases.linaro.org/14.11/components/toolchain/binaries/armeb-linux-…
Finally, there appears to be some inconsistent usage of tuples in the download
directories. Would it be possible to use the same tuple for a particular
toolchain everywhere that tuple is used? For example, for the arm-none-eabi
toolchain, the directory is "arm-none-eabi", but the compiler tarball has only
"arm-eabi".
Thanks,
Chris

== Progress ==
* Automation Framework (CARD-1378 1/10)
- Setting up new box
* Release 3.6 (CARD-1431 5/10)
- Looking for the patch that introduced a major NEON regression since December
* Background (4/10)
- Code review, meetings, discussions, etc.
- More Jira farming...
- Some EuroLLVM paper reviews
- LLVM/Android planning
== Plan ==
* Keep trying to find the bug in release 3.6
* Try to have some time to fix the NEON unwinder issue
* Preparing for Connect
== Issues ==
I cocked up the LLVM 3.6 ARM release last December when I
inadvertently ignored a bug report about clang not self-hosting on
NEON machines. To make matters worse, I was the one that decided to
move *all* our buildbots to non-NEON machines, expecting that the
test-suite on a Chromebook would catch all NEON problems.
There are limits to human intelligence, not human stupidity.
== Progress ==
* LLD (1/10, TCWG-561, TCWG-563, TCWG-570)
- Updated and added more cards, adding more detail and loose priorities
- Rebased, fixed up and resubmitted relocation test patch
* AArch64 ILP32 toolchain (4/10)
- Attempted various SPEC2k runs and fixed issues found
* Submitted patch for AArch64 -Bsymbolic ld issue (1/10)
* Connect slides (2/10)
* Other stuff (1/10)
- Email, meetings, etc.
* Tuesday looking after sick child
== Issues ==
* Juno access has been patchy
== Plan ==
* Get SPEC2k running ok on Juno and with ILP32
* Push remaining LLD patches
