* 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

=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
== Progress ==
* Reviewed a big pile of benchmarking patches for cbuild2. (TCWG 1378
- 2/10).
* Worked on stabilizing "Backport" Jenkins job (TCWG 1378 - 6/10).
* Meetings and Misc (2/10)
== Plan ==
* Keep tracking down Jenkins issues with Backport job.
* Get my D01 board working finally, since I killed my Odroid U2.
* Do more thorough testing of SSH performance improvements.
=Progress=
cbuild2 benchmarking - TCWG-360 [4/10]
* Some disagreements with gerrit
* One of my patches broke bare metal builds (now fixed)
* More review of the way we store benchmark sources
Other - [5/10]
* Meetings, mail, etc (featuring newlib build options, defaults,
cbuild vs benchmark scripts)
* Learned to use git-send-email, bent it to my will
* Authentication pain on ARM-side
Holiday - [1/10]
=Plan=
cbuild2 benchmarking
* Finish source/data storage plan
* Figure out how benchmark cross-running will work, get started on it
Holiday next week (25th - 29th August)
