= Progress ==
* Continue improving LAVA support in DejaGnu. (TCWG 455 - 1/10)
* More work on regression test analysis and reporting. (TCWG 448 - 4/10)
- Did builds of 4.8, 4.9, and master to establish baseline test
results.
- Worked on test analysis script.
- Jenkins matrix builds & test runs are working, and copying results to
toolchain64.
* Meetings and Misc (5/10)
- Fixing various Cbuildv2 bugs found by yroux dealing with git.
- Fixed bug where the GDB build was polluting the destdir with
binutils.
- Installed OpenNX chroot on toolchain64 with maxim.
- Fixed disk on toolchain64 with maxim to access all 4TB. Use GPT...
- Added more config triplets to Jenkins, so now it builds everything
we support.
== Plan ==
* Install lava-tool and get it working on all the tcwgbuild* machines.
* Continue improving LAVA support in DejaGnu. (TCWG 455)
* More work on regression test analysis and reporting. (TCWG 448)
- Do diffs of new builds test runs from the baseline, not the previous
build.
* Try to look at the LLVM branch of Cbuildv2, do some testing of it.
== Issues ==
* Jenkins needs to be able to see LAVA slaves as online, but not
booted..
* The skiing is good, but the avalanche danger is high, so limits
accessibility.
* We need a backup plan for toolchain64.
* Google groups have problems, so had to setup test results list on
one of my servers instead. (ask me if you want to be on the list) The
new beta release of GNU Mailman looks very nice.
* The chromebooks in our build farm can't build GCC native.

== Issue ==
* None.
== Progress ==
* Identify a build environment issue for linux64 gdb binaries "Symbol
format `elf32-littlearm' unknown".
* Send out shrink-wrap related patches from community review (TCWG-133, 2/10)
* Move-loop-invariant heuristic tuning (TCWG-469, 8/10).
- Update heuristic according to benchmark testing.
== Plan ==
* Update shrink-wrap patches according to comments.
* Continue on move-loop-invariants heuristic tune.
== Planned leaves ==
* June 2.

Holiday [2/10]
Fixing performance bugs in lowlevellock - TCWG-435 [4/10]
* Initial patch for lowlevellock.h largely done, awaiting an aarch64 test run
* About 1/2 of the lowlevellock.h's remain post-patch, need to ask
some questions about them
cortex-strings memset - TCWG-156 [1/10]
* Fixed an alternative implementation, a little more benchmarking investigation
cbuild benchmarking branch [1/10]
* Hunting for correct benchmark source, added a little more error checking
Meetings/mail/etc [2/10]
== Plan ==
More of the same -
* Post lowlevellock.h patch and ask some questions
* Finish exploring memset alternatives and work out how to benchmark them
* Carry on with cbuild benchmarking branch
Holiday 26th - 30th May
== Progress ==
* Kernel (CARD-1246 3/10)
- Committed Named Register LLVM change
- Working on the Clang part
- Helping LLVMLinux to set up bots/LAVA tests
* Tests/CBuild2 (CARD-716 2/10)
- Submitted CBuild2 LLVM patch, waiting for review
- Implemented sqrt to pacify GCC on sphereflake
* Background (3/10)
- Code review, meetings, discussions, etc.
* Bank Holiday Monday (2/10)
== Plan ==
* Continue named registers on Clang
* Continue LLVMLinux hardware test bot
* Run some benchmarks on AArch64
* Check CBuild2 progress, try builds live
== Progress ==
* Bank Holiday Monday (2/10)
* glibc patch review and followup (1/10)
* Started investigating malloc intensive applications (3/10, TCWG-440)
* Investigate a couple of linker issues (1/10)
* Figure out how to benchmark postgresql (3/10, TCWG-441)

Bank holiday [2/10]
Investigated using D01 board [1/10]
Retested and pinged division patch - TCWG-293 [2/10]
Added post-index addressing to NEON memory access for ARM -TCWG-430 [5/10]
* wrote patch
* makes useful improvement to libvpx performance
== Progress ==
Holiday [3/10]
Post-indexed addressing for NEON on Aarch64 - TCWG-430 [3/10]
* needs much more work than for ARM
Revisited apparent NEON scheduling problem in libvpx - TCWG-429 [2/10]
* it transpires that this was an incorrect analysis
* the assembler code didn't conform to the ABI
* upstream has now fixed this
Received review for division patch - TCWG-293 [2/10]
* needs a rewrite
(Resending to correct address)
== Progress==
TCWG-435 needless busy-wait in lowlevellock.c (0/10)
* Patches for lowlevellock.c sent to list
* Patch for lowlevellock.h still to do
TCWG-156 cortex-strings memset (5/10)
* Dug through a bunch of docs and fiddled with the source
Looking at the cbuild benchmarking branch (2/10)
* Some back and forth around getting access to lava lab
* Poked around the code, made some small improvements
== Misc ==
Meetings/mail/etc 3/10
== Plan ==
(Public) holiday on Monday
Put together lowlevellock.h patch
Do something more substantial with cbuild
Finish fiddling with the memset source
== Week of April 28th ==
- Made a prototype rootfs for benchmarking (CARD-1413, 2/10)
-- Got a tutorial from Fathi on how to build openembedded rootfs.
-- Wrote up notes at https://collaborate.linaro.org/display/TCWG/How+to+build+openembedded+rootf…
- More benchmarking setup (TCWG-413, 2/10)
- Various discussions (3/10)
-- 1-on-1 with Venkat (NX setup and GCC reload problem)
-- 1-on-1 with Kugan (benchmarking handover)
-- 1-on-1 with Michael (var-tracking investigation)
-- 1-on-1 with Rob (command-line access to LAVA and job submission)
- Made NX/schroot rootfs (3/10)
-- This can be deployed on Linaro [build] servers and provide standardized development environment for toolchain work.
-- More details to follow.
- Misc
-- Reported a kernel oops related to networking on vexpress64.
- Tyler Baker of the LAVA team deserve a special mention for answering all the questions about LAVA from the toolchain group!
