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!

== This week ==
- Investigated infinite loop bug [TCWG-290][6/10]
- Narrowed bug down to data flow analysis of micro operation in
variable tacking pass
- Created bugzilla report
- Still debugging to determine cause of infinite loop
== Next week ==
- Attend ARM Big Picture conference, May 5th-7th
- Resolve infinite loop bug
== Future ==
== Progress ==

* More work on regression test analysis and reporting. (TCWG 448)
== Progress ==
* GDB reverse debugging on aarch64
-- Further progress on decoding of aarch64 load store instructions.
[TCWG-401] [1/10]

== Progress ==
* TCWG-447 (5/10)
* Re-spin few versions of the patches and posted after testing based
on reviews.
* http://gcc.gnu.org/ml/gcc-patches/2014-04/msg01743.html
* http://gcc.gnu.org/ml/gcc-patches/2014-04/msg01744.html
* TCWG-413 Spec2006 (5/10)
* Updated the scripts to deploy libraries and to run cross spec
benchmarking with them.
* Experimented with open embedded image generation for benchmarking-
still finding some issues even with a trusty chroot.
* Started benchmarking and variance analysis.
== Plan ==
* Benchmarking.
* Upstream zero/sign extension elimination activities.
* Start with literal pool merging.
Very short week (3 half days)
== Progress ==
* GCC trunk cross-validation (2/10):
- monitored results, and reported some regressions/new fails
- moved away from Jenkins
- as commit rate has decreased, there is no backlog in validations
* Neon-intrinsics test (1/10):
- Continuing conversion for inclusion in the GCC testsuite.
- Preparing an additional Makefile, simpler than the current one,
to help using the testsuite for various GCC variants until
conversion is complete.
== Next ==
* Continue to closely monitor GCC trunk validations
* Neon intrinsics tests
* Off Thursday/Friday
