== Progress ==
* LR register not used in leaf functions (TCWG-539) (1/10)
Reviewed Jiong's changes.
* bug #412 (2/10)
- Seems to have been fixed but since there is not specific test-case
except that it happens with spec2k gcc, need more work to be entirely sure.
* AArch64 Spec2006 int regression (1/10)
- Looked at bug databases and mailing list archive for more information
* armv3 (bug #85 and bug #410) (2/10)
- Looked at both the outstanding bug to find more information
- proposed using -mno-lra for armv3 after discussion with the team
* Misc (2/10)
- Public holiday (2/10)
- Annual Leave (2/10)
== Plan ==
* zero/sign extension elimination with widening types
== Holidays ==

- Developed fix for vclz DejaGnu failure
- Tested on ARM hardware
* Linaro bugzilla 602 - gcc 4.7.3 compiler internal error while building
hsail components (1/10)
- Unable to reproduce with either Linaro 4.8 or 4.9
* Linaro Bugzilla 540 - Median of three has unneeded register moves (1/10)
- Results of Triage indicate generated code has improved though still
not optimal
- No plans for further improvement
* Misc. (1/10)
- Completed ARM annual review paperwork
* Out sick Friday, October 3rd (2/10)
== Next week ==
- Full validation testing on vclz bug fix
- Create patch for vclz bug fix and send to gcc-patches list
- Resolve any blocking issues to patch for bugzilla 331
= Progress ==
* Core mark benchmark and report for PGO and PGO + LTO (2/10)
Collected benchmark scores and report sent internally.
Adding PGO benefits coremark. LTO seems to hurt. More runs and profiling
next week. Tired few experiments with -funroll-all-loops and seems to
benefit.
* Misc [2/10]
Internal meeting and 1-1 with Ryan and inline manger.
Revisited and closed PR61442
Short week leave on 29 Sep, 2 and 3rd Oct (6/10).
== Plan ==
* Coremark benchmark and profiling for PGO and PGO + LTO
* Investigate PR 62308
* Setup Cbuildv2 build in internal machine.
== Progress ==
* Fixed test infrastructure bugs (TCWG 1378 - 8/10).
- Installed Foundation Model on all Hetzner machines so
aarch64 bare metal testing works.
- Refactored all board support files to eliminate duplication to
reduce maintainance headaches. Fixed ldflags so now getting
good results.
- Backport job is working good now.
- Worked on Gerrit/Jenkins integration, with the goal of having
the notifications work *after* the test and validation is done.
- More work on optimizing SSH connections by reducing extraneous
commands in the test framework.
- Recreated stable branch from master now that results are much
better.
* Meetings and Misc (2/10)
* Fixed National Park internal wireless network, getting access to
much better bandwidth than the crappy Guest one. :-)
== Plan ==
* Escape Yosemite, hard during a great weather window, and being
the only person in my group with a job...
* Continue fixing remote testing support, merge "boards" branch
into master, then make it stable after more testing.
== Progress ==
Closed bug #405 (not a bug)
NEON load/store
. reworked patches not to do type-punning [9/10]
. investigated alternative ways to solve poor code generation with
array of vector types
Started investigating NEON bugs 403, 418 [1/10]
== Plan ==
NEON load/store - submit new patches, continue upstream discussion
Try out validation infrastructure for my own patches
== Progres ==
* GCC trunk/4.9 cross-validation (CARD-647) (3/10)
- aarch64 address sanitizer tests currently all fail at execution
under qemu because they try to reserve 50GB of memory. Tried to push
the limits with no success so far.
- working on fixing support for testcases generating a shared lib
- newly introduced abi_check for aarch64 fails on my side, probable
testsuite configuration problem.
* Linaro branches
- updated backports spreadsheet
- reviewed backports prepared by Yvan
* Validation (3/10)
- manually running builds+validations to compare master and chroot
branches, see the diffs between static and dynamic libs in terms of
PASS/FAIL, ....
* Neon intrinsics tests (1/10)
- No need to comply to the GNU coding style since it's imported from
and existing testsuite.
- only minor changes requested
- should help having the 1st subset committed soon
* Misc (3/10)
- calls/meetings
- bugzilla admin etc..
