Sorry for sending this late this week.
== Progress ==
* Ran gdb testsuite on arm and x86. Investigated failures on
arm-native-gdbserver config. [2/10]
* Investigate shared library gdb test failures with dejagnu on remote
connections. [TCWG-504] [2/10]
* Debug AArch64 GDB reverse watchpoints issue. [TCWG-503] [2/10]
* Debug AArch64 GDB handling of functions with empty prologue. [TCWG-504] [2/10]
* Understand gdb remote vs native feature parity patches. [1/10] [TCWG-263]
* Miscellaneous [1/10]
-- Setting up chromebook with 14.04
-- Meetings etc.
== Plan ==
* Further progress on AArch64 GDB reverse watchpoints issue. [TCWG-503]
* Further progress on AArch64 GDB handling of functions with empty
prologue. [TCWG-504]
== Progress ==
* Track down and fix build, testing, and Jenkins issues. (TCWG - 1378
9/10)
- Reinstalled everything needed for toolchain build and Jenkins on
the repaired chromebooks.
- Setup D01 and APM boards for toolchain building and testing,
added them to the Jenkins matrix.
- Updated qemu to the latest to get aarch32 & crypto support.
* Meetings and Misc (1/10)
== Plan ==
* Fix bare metal testing for aarch64.
* Continue working with the D01 boards.
* Track down and fix build, testing, and Jenkins issues. (TCWG - 1378)
== Issues ==
* Gerrit triggers only build trunk, and not the branch specified
in the review request.
== Progress ==
* More work on malloc microbenchmark (5/10, TCWG-160)
- Script for plotting results
- Analyze performance with SystemTap probe points
- Tidy up and submit v3
* Further work on ld issue on master (1/10, CARD-341)
* Patch review and testing (2/10, CARD-341)
* Annual leave on Friday (2/10)
* Still no luck on getting Ubuntu on wg boards
== Issues ==
* None
== Plan ==
* Make sure we have everything we need for glibc freeze at month end
* malloc app benchmark work

=Progress=
memcpy regression on A9 - TCWG-390 [6/10]
* cortex-strings benchmarks suggest this isn't just an outlier, nor
entirely about preload
* Quick test on A15 suggests a similar (less severe) issue
* Got cortex-strings benchmarks more-or-less running via lava
memset performance improvement - TCWG-156 [1/10]
* GNU benchtests not as repeatable as hoped
lowlevellock performance bugs - TCWG-435 [1/10]
* Converted a bunch of inline functions into macros for coldfire
Meetings/mail/etc [2/10]
=Plan=
Carry on generating memcpy data, develop some hypotheses
Bugfix lava-ization of cortex-strings benchmarks as & when
Explore repeatability of cortex-strings benchmark
See how much quicker I can make cortex-strings benchmark without
compromising repeatability
Try to get lowlevellock.h committed for at least arm/aarch64
== Progress ==
* TCWG-418 : Bug fix Reload spill failure (3/10)
Bench marked coremark – no degradations with patch.
CPU2000 runs – Workedon running them as native in chromebook.
Issues with space.
* TCWG-181 : LTO enablement (3/10)
GCC 4.9 FSF no ICE . Linaro 14.07 release has ICE.
GIT bisect experiments on trunk on Aarch64 hardware.
* Misc: (2/10)
- Various meetings .
- PGO bootstrap runs on Aarch64 hardware - pass.
* AMD team out on 19th (2/10).
== Next ==
* GIT bisect experiments on LTO bootstrap.
* Continue Benchmark reload spill failure fix
* Explore on Large memory model support for aarch64
* Cbuildv2 release packaging on native.
== Progress ==
* Benchmarking and regression testing (TCWG-468) (3/10)
- More aarch64 spec2k benchmarking of patches and against fsf 4.9 release
- Spec2k a15 benchmarking on chromebook
* Zero/sign extension elimination (TCWG-15) (5/10)
- Fixed regressions found and broke the patch into two
- Looking at improving zero/sign extension elimination as it is not
happening for one test-case now
- Plan to benchmark the changes and post for review once this is done.
* LP spec2k regression bugs (2/10)
- #1320965 : Cant reproduce ICE but goes into infinite loop with
-floop-interchange at -O3; Looking into it
-#1330725 : Invalid as -fno-strict-overflow is needed for 254.gap.
== Plan ==
* Benchmarking and spec2k bugs.
* Upstream zero/sign extension elimination activities.
== Issues ==
* None.
== Progress ==
* loop2-invariant heuristics tuning (TCWG-469, 2/10). Two patches were
committed @r211818 and r211885. Another two are in review.
* Test the rebased ccmp patches (TCWG-488, 2/10).
* Send out a patch to enhance cprop pass by checking rtx_cost. Collect
benchmark results and update the patch according to comments
(TCWG-486, 6/10).
== Plans ==
* Ping pending patches.
* Continue on patches to optimize constant in loop.
