- No builtin wifi but dongle works ok
- Breakpoint issue fixed but the test still fails for some other
reason, created upstream issue
* Malloc application benchmarking (3/10, TCWG-441)
- Various improvements of the scripts
- Investigate benchmark variability in the presence of frequency scaling
- Is it possible to get repeatable numbers on Intel i{7,5,3}?
* Start looking at LCU session requirements (1/10)

== Progress ==
* TCWG-180 Debugging - LTO bootstrap failure in Aarch64 with GCC 4.9. (4/10)
Completed. Patch that sets same tune parameters solves the bootstrap
compare errors in Branch. Closed the JIRA cards. There are still LTO
IR streaming issues in trunk which needs to tracked down and fixed at
tree level. and no plans of doing that now.
* TCWG-520 ICE in linaro compiler for ARMv7 target. Bisected the
revision in trunk which fixes that. Backported and tested and fixes
tha bug. (4/10)
* Others (2/10)
* Bug migration from launchpad
* Meetings Christophe, Ryan, Maxim and GCC status meeting
* Misc and internal meeting.
* setup LLVM.
== Plan ==
* Continue Bug fix (TCWG 520).
* Benchmark Core mark with LTO (TCWG-181).
* Upstream patch review.
== MISC ==
* Local Holiday on 29th August
== Progress ==
* TCWG-413 - Release benchmarking (2/10)
- Analysed all the patches gone into the release for performance impact
* TCWG-521 - Analysed Coremark and Spec2k for uxt/sxt optimizations
TCWG-521(3/10)
- Studied Coremark and have additional patches in development for
missing cases.
* bswap pr43550 (No card yet) (3/10)
- Looked at the pr and it is not fixable with VRP
- An alternate approach based patch is in testing to fix this.
* 1 day off Sick (2/10)
== Paln ==
* Continue with TCWG-521 and bswap pr43550
== This week ==
* TCWG-515 - Neon intrinsic testing part 1 (1/10)
- Attempting testing on ARM targets; resolving build failures
* TCWG-524 - Neon intrinsic testing part 4 (2/10)
- Completed AARCH64 testing with no regressions found
* TCWG-525 - Neon intrinsic testing part 5 (2/10)
- Completed AARCH64 testing with no regressions found
* Launchpad 1312931- gcc 4.8 internal compiler error: in add_stores, at
var-tracking.c (3/10)
- Resolved, tested and requested code review on linaro 4.8 branch
- Resolved and tested on linaro 4.9 branch.
- Reviewing test results
* Linaro Connect Presentation (2/10)
- Met with Maxim and Will to prepare outline
- Began writing "Optimization Levels" portion of presentation
== Next week ==
- Continue Neon intrinsic testing including getting ARM portion to execute
- Complete "Optimization Levels" portion of Linaro Connect presentation
- Resolve Launchpad 1312931 on Linaro 4.9 branch
=Progress=
cbuild2 benchmarking - TCWG-360 [5/10]
* Proposed a plan for benchmark storage
* A bit more thought on cross-running
* Prototyped script to launch/run/release on LAVA targets (e.g. wg)
** The 'run' part is pretty much independent of the 'LAVA' part
lowlevellock.h commentary - ???? [2/10]
* In response to a patch review, added some comments to this fairly obscure file
* Took longer than expected, but the end's in sight so I guess I'll finish
* I know a bit more about futexes and threads now
Meetings/mail/etc [3/10]
=Plan=
Holiday. Back on 1st September.
== Progress ==
Arm gdb record-replay bug fix [4/10] [TCWG-314]
* Testing of all patches on x86 and arm machines.
* Patch submission upstream after sync up with latest gdb trunk.
AArch64 gdb record-replay bug fix [3/10] [TCWG-503][TCWG-498]
* Debugging of testsuite failures with apm and foundation mode.
* Patch series update after sync up with latest trunk.
GDB Tracepoints/Fast Tracepoints support on arm [2/10] [TCWG-480]
* Search for previously submitted patches, wiki info and other documentation.
* Started with initial study and code understanding.
Miscellaneous [1/10]
* Research GDB record/replay usage scenarios.
* Meetings/emails and installation/configurations etc
== Plan ==
AArch64 gdb record-replay bug fix [TCWG-503][TCWG-498]
* Fix test failures if possible otherwise submit updated patches.
GDB Tracepoints/Fast Tracepoints support on arm [TCWG-480]
* Further study and investigate a missing functionality on arm.
Verify GDB non-stop debug support on ARM. [TCWG-246]
== Progress ==
* Looked at implementation options for backlog cards and
closed/postponed cards that doss not benefit or cards that require
excessive re-architecture that will not be possible now. (5/10)
- TCWG-468 - Postponed after detailed study and discussion.
- TCWG-412 (Support literal/constant pool sharing (wont-fix): As it is,
intra procedularl literal pool fix happens in
TARGET_MACHINE_DEPENDENT_REORG with arm_reorg. It is quite complex and
somewahat hacky. it would become even more messy if we are to record
these information and reuse it for whole program as a way to share
literal poool. Additionally A-profile (which is Linaro's focus) dosent
benefit from this as we use movw/movt instead. Therefore decided to
clsoe this as wont fix.
* TCWG-413 - Release benchmarking (2/10)
- Benchmarking or release for a15 and a57
* Analysed coremark and spec2k for uxt/sxt optimizations (3/11)
- Studied coremark and have additional patches in development for
missing cases.
* Misc
- Looked at bug database and monitored patches relevant to arm/aasrch64
== Paln ==
* Look at open uxt/sxt bugs in gcc bugzilla
* Study coremark and then spec2k for uxt/sxt
