== Progress ==
LLDB development
-- LLDB Call graph analysis for understanding some development nits [1/10]
-- Trying out LLDB server arm and aarch64 cross compilation. [2/10]
-- List down arm-lldb task list with some debugging [2/10]
Miscellaneous [1/10]
-- 96board setup
Holiday [4/10]
-- Monday 16th and Tuesday 17th Feb 2015
== Plan ==
Convert LLDB Arm task list to JIRA cards
Try to fix LLDB server arm and aarch64 cross build issues.
Some GDB patch updates
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.
* GCC mailing list.
Leave on 20-Feb-2015 (2/10)
== Plan ==
* TSAN support for Aarch64 work fixing GCC -fsanitize=thread option.
* Break tasks under TCWG-581.
* LLVM build with local patches.
* Bug869.
* Misc and Meetings (AMD, LInaro)
== Progress ==
* compiler-pass to widen computation (TCWG-547) - (5/10)
- Analysed core-mark code size regression
- fixed constant handling
- Added VRP support for ZEXT_EXPR
* Improve register allocation for AArch64 (TCWG-620) - (1/10)
- Looked at the relevant patches
* Misc (4/10)
- Setting up ABE benchmarking scripts
- Ran into some LAVA related issues for ABE benchmarking
- Recovering from connect
- Started with 69 board setup
== Plan ==
* TCWG-620 and TCWG-547
* ABE benchmarking
== Progress ==
* GCC trunk/4.9 monitoring
* Neon intrinsics tests
- committed the last patch of the 2nd series.
- about another 1/3 of the tests remain to be converted: will wait
for GCC stage1
* AArch64 sanitizers (2/10)
- 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.
- preparing a patch to solve the long standing issue with dependency
on aarch64 kernel version (kernel_old_[ug]id)
* Backports (4/10)
- reviews
- respawned validations under MergeFarm
* ABE:
- improving reporting
* Misc (4/10)
- meetings, conf-calls, emails, ....
== Next ==
Connect, then holidays
== Progress ==
* Rebooting brain after Connect (2/10)
* Friday off (2/10)
* Release 3.6 (CARD-1431 1/10)
- Spinning RC3, RC4
- Long discussions about Phoronix benchmark regressions
* Buildbots (CARD-1823 2/10)
- Buildbot cleanup and reshape
- Adding two new internal buildbots
- Investigating AArch64 broken bot
* Background (3/10)
- Code review, meetings, discussions, etc.
- Sprint planning
- Catching up on emails
- Servers purchase
- EuroLLVM paper reviews
== Plan ==
* Install new servers when they come
* Add the two new bots upstream
* Plan LLDB with Omair, contact Google
* Plan TSAN with Venkat
* Help Christophe investigate ASAN on AArch64
Holiday [3/10]
ABE benchmarking automation - TCWG-360 [3/10]
* Initial Jenkins implementation
Investigating cache effects on Juno - LDTS-1238 [2/10]
* One effect due to write streaming, others still to look at
Misc [2/10]
* Unpacking, some background catomics
Connect [10/10]
=Plan=
Carry on with Jenkins implementation
Run some benchmarks on catomics
Juno cache effects
Write up/think about where to go with libm exercising
ABE benchmarking automation - TCWG-360 [8/10]
* Pursued sneaky bugs through twisty mazes of bash
* Learned that ControlMaster does not play nice with my scripts
* Learned more about IPC pitfalls
* Cleaned up build behaviour of scripts somewhat
* Implemented support for benchmarking against sysroot (needed by Will
and by me)
* Generally tried to help Charles
* A bit of Jenkins testing
Misc [2/10]
* Featuring part 1 of an office move
=Plan=
Holiday Wednesday, 1/2 of Thursday
Part 2 of office move
Support benchmark users
Look more at cache effects on Juno
Get Jenkins working
Benchmark catomic patches (as much as I can without putting even more
pressure on the Junos)
Write up/think about where to go with libm exercising
Final preparation for Connect
