== Progress ==
* Holidays (3 days)
- Clearing emails/tasks backlog
- Some post-trip illness
* AArch64 vs. ARM64
- Comparing performance of both back-ends
* Named Register
- Re-implementing after code review
- http://reviews.llvm.org/D3261
* Time
- CARD-1246 4/10
- Others 6/10
== Plan ==
* Finish named register in LLVM, check Clang
* Continue testing and benchmarking ARM64 back-end
* Have a try at CBuildv2
== Progress ==
* Back to work part-time (50%) for the next 3 weeks
* Easter Monday (1/5)
* (No Jira card - 2/5)
Analyzed at GCC trunk validations and reported some regressions.
The current commit rate is very high since stage1, and our compute
farm isn't fast enough. Should be OK after the week-end.
Modified my scripts so that I move these validations out of Jenkins.
* (No Jira card - 2/5)
Continued converting Neon intrinsics tests for inclusion in GCC testsuite.
To make the review easier, I now believe that it would be better that
I convert most of the testsuite first, and rework the patches order.
* Meetings and conf calls(1/5)
== Next ==
* Continue to closely monitor GCC trunk validations
* Neon intrinsics tests
* Off Thursday/Friday next week

. if interested, you can read the report in card 429:
https://cards.linaro.org/browse/TCWG-429?focusedCommentId=22247
tested division optimisation patches against current trunk and pinged
on list [2/10]
good friday bank holiday [2/10]
=== Next ===
Resume looking at NEON scheduling TCWG-135, which ties into libvpx
Upgrade laptop to Ubuntu 14.04 LTS
== Progress ==

-- Scored through a64 instruction set details. [1/10]
-- Completed testing and implementation of all basic structures.
[TCWG-398] [1/10]
-- Started decoding aarch64 load store instructions for recording.
[TCWG-401] [2/10]
-- Completed decoding of aarch64 branch instructions. [TCWG-400] [2/10]
-- Scored through a32 instruction set and researched on a32 recording.
[2/10]
* Miscellaneous [2/10]
-- UK visa application process
-- Tools cauldron and TCWG sprint bookings etc.
-- Meetings
== Plan ==

PGO - AArch64 (TCWG-179) (4/10)
* Completed SPEC runs -O3 -mcpu=cortex-a57 in chroot + qemu
arm64-saucy with Linaro release source (4.8) march 2014.
* Built Linaro 4.9 GCC branch based tool chain under chroot + qemu arm64-saucy
* Created a PGO config file for aarch64 as a peak configure and use --tune=peak
SPEC gave warning that FDO cannot be used as base flags and will
ignore the flags.
Also setting basepeak = yes gave issues and ran base runs and
setting it to no does both base and peak runs
* Started SPEC2006 runs for PGO under chroot + qemu arm64-saucy
* Perlbench train run failed in qemu.
* Other benchmarks are progressing.
GLIBC Systemtap (2/10)
* Ran glibc make check under qemu. Seen some illegal instructions and
ntpl tests hung in qemu aarch64. Will has completed these tests in
hardware.
Misc (2/10)
* Tested cbuildv2 to build gcc natively under qemu-arm64-chroot-ubuntu-saucy.
git gave issues not able to clone and hangs when downloading
binutils and gdb repos.
* 17th was Public Holiday (2/10)
== Plan ==
* Go through the results for SPEC2006 PGO runs.
* Start functional PGO runs for SPEC2000
* Bug fixing.
== Issues ==
* Toolchain64 disk full
== Progress ==
* Linaro GCC 4.9 2014.04 (3/10)
- Created FSF Linaro 4.9 branch
- Testing FSF 4.9.0 RC
* Launchpad bugs: (3/10)
o LP #1169164 : including signal.h exposes various PSR_MODE #defines
- Two possible ways to fix the issue (to be discussed with maintainers)
* Misc:
o Cbuildv1 baby-sitting (1/10)
o Various meetings (1/10).
== Next ==
- Easter Monday off
- Continue on LP #1169164
- Linaro GCC 4.9 release (when FSF release will be made)
== Week of April 14th ==
- Benchmarked autoprefetcher patches. (TCWG-388, 2/10)
- Continued working on spec2xxx-utils scripts. These are now gaining support for AArch64 and SPEC2006. (TCWG-238, 4/10)
- Various discussions. (2/10)
- Short week due to Good Friday / Easter. (2/10)
== Week of April 21st ==
- Take Tyler B.'s LAVA test definition for SPEC benchmarking and adjust spec2xxx-utils scripts to match LAVA environment.
- Investigate regressions on gap, eon and wupwise from autoprefetcher patches.
-- SPEC2000's gap in particular is sensitive to 1st scheduling pass with register pressure, and, apparently has a 5% performance improvement potential (at -O2 Cortex-A15).
- Various discussions.
- Even shorter week due to Easter Monday and ANZAC Day on Friday. (4/10)

== Progress ==
* TCWG-238 (4/10)
- Created scripts and spectools for spec2006 to work with cbuild2
* TCWG-413 Spec2006 (4/10)
- Worked out Spec2006 config and src.alt for v1.1 src we have to work
correctly
- Got it to work natively with Maxim's scripts
- Did a trail run in apm openembedded; Needs ccrypt, tar with xz
compression support and system binutils with -mabi=ilp64 support
* 18th is Public Holiday (2/10)
== Plan ==
Benchmarking and FENV support
== Progress ==
* Attempted to get qemu-aarch64 working, fails on saucy, works on
precise. Did native build, hung during 'make check'. Setup
qemu-aarch64 chroot on all TCWG x86_64 build farm
machines. (4/10)
* Tracked down problem that's kept TCWG Jenkins from
working. (1/10)
* Tried Kugan's benchmarking branch of cbuildv2. (1/10)
* More work on Neon intrinsics tests. (TCWG-322 - 1/10)
* Meetings and Misc (3/10)
- Worked on benchmarking doc with Ryan.
== Plan ==
* Get Jenkins working with matrix builds so we can utilize all LAVA
slaves.
* More experimenting with Kugan's benchmarking branch.
