== Progress ==
* Short week due to GNU Cauldron Travel
* Widening pass (TCWG-547) - 3/10
- Looked at the false positive warning for uninitialized variable
- Have a reduced test-case and looking at ways to fix this
- Split the patch for easy review
- Fixed test-cases and going through all the test-case failures
* Misc - 2/10
- gcc-patches, gcc-bugs list
- Looked at gcc vectorization
== Plan ==
- Widening pass
== Progress ==
o Linaro GCC validation (4/10)
* Validation issues investigation
* Austin's APM board seems more reliable
* New validation instability on x86_64 discovered:
- Analysis on-going but it is related to fstack-protector
* Waiting for VPN access
o Upstream GCC (4/10)
* Reworked OOM issue on armeb-linux-gnu target fix
* Patch committed on trunk
* Backport on gcc-5 validated and about to be committed
o Misc (2/10)
* Various meetings
* Team member support
== Plan ==
o Continue on validation
o Redo FSF branch merge after big-endian fix committed.
Benchmark infrastructure - TCWG-360 [6/10]
* Fixed remaining known critical issues in multinode
** Testing stymied by LAVA oversubscription
** Attempted to implement some workarounds for oversubscription
* Some discussion/investigation on generating filesystems for benchmarking
* Started brain-dumping state of infrastructure into cards.linaro.org
Bringing up Juno for noise control experiments [1/10]
* Some struggles with firmware/bootloader configuration
Misc [3/10]
Featuring some ARM management duties
= Plan =
* Get benchmarking tests through, if LAVA permits
* Fix any critical issues discovered
* Finish brain-dump into cards.l.o
* Bring up Juno for noise control experiments
* Some more ARM management
== This week ==
* TCWG-140 - Transform end of loop conditions to min_expr (4/10)
- Wrote initial test case as requested by maintainers
- Need to determine how to not run test case on targets with no
MIN_EXPR/MAX_EXPR
* TCWG-833 - Exploit Wide Add operations when appropriate (4/10)
- Fixed internal error by using unspec for vector sign/zero-extend
- Fixed multiple issues with test cases
- Investigating why gcc.dg/vect/slp-reduc-3.c with lto is regressing
for aarch32 and aarc64
- Investigating two additional regression failures on aarch64
* TCWG-834 - Use non-unit stride loads by preference when applicable (1/10)
- Spoke with Richard Biener at GNU cauldron.
- He indicated this was a problem with a interaction problem with
vectorizer not attempting multiple strategies
- He indicated that he planned to fix this for GCC 6 and not to
attempt a fix
- My plan is to write a test case that fails until the issue is
addressed in GCC 6
* Misc (1/10)
- Conference calls
== Next week ==
- Resolve testsuite regressions for TCWG-833
- Create bugzilla reports for TCWG-833 and TCWG-834
- Write testcase for TCWG-834 and submit upstream
- Investigate TCWG-832 as time permits
== This Week ==
* TCWG-777 (4/10)
- Working on RTL pass, prototype patch works for the test-case.
- updating the trunk to r226907 , it appears combine can fold
arm_andsi3_insn/arm_cmpsi_insn
into zeroextractsi_compare0_scratch at -O2 while not at -O1.
.* TCWG-835 (2/10)
- Testing patch with Spec 2006
- Found ICE unrelated to my patch
* Misc (4/10)
- Travel to home from GNU Tools Cauldron 2015, Prague.
== Next Week ==
- Continue working on TCWG-777
- Continue testing TCWG-835 patch with SPEC 2006
== Progress ==
* Buildbots (CARD-1823 6/10)
- Setting up new APMs
- Running around for a decent UEFI, Kernel, Distro
- Testing different builds, configurations
- Managed to get one APM doing the test-suite *only*! sigh...
- http://buildmaster.tcwglab.linaro.org/builders/clang-cmake-aarch64-lnt
* Background (4/10)
- Code review, meetings, discussions, etc.
- Doing more reviews than usual due to buildbot work being erradic
- Laptop is playing stupid again
== Plan ==
* Moar bots
* Moar code review
* Maybe some vodka, to wash it all up
