* Validation
- disabled Auto Backport Engine until the patch selection
is improved to avoid saturating the builders with undesirable
builds.
- AArch64 bare metal validation (bug #2011). Submitted a patch
for dejagnu aarch64-fv8.exp, and one for our builders schroots.
Will need another patch, in ABE.
- timeout issues: no progress
* Misc (conf calls, meetings, emails, ....)
- internal discussions

Hi,
My ARM target runs glibc 2.13 and I am having a hard time finding a
linaro toolchain for it. It seems like all the ones I have found ship with
glibc 2.15 (even old ones).
Where can I find the binaries for a linux toolchain that targets armhf
with glibc 2.13?
Thanks in advance
Port to microinstance - TCWG-432 [4/10]
* Went a few more rounds with the race condition, finally nailed it
* Tidied up transfer of Coremark results to LAVA
* Added metadata to LAVA results
* Sketched some charts using LAVA reporting
* Improved runtime benchmark logging
Benchmarking infrastructure documentation - TCWG-496 [2/10]
* Most everything drafted, some docs finished
Controlled image builds - TCWG-360 [2/10]
* Reached a better understanding of what a hwpack is
* Generated a few images, none of them booted
Misc [2/10]
=Plan=
Benchmarking-102 slides for Connect
Finish documentation
Backport benchmarking

o Infra/Validation (1/10)
* A couple of patches for release script.
o GCC dev. (2/10)
* Remote testing sanitizing: still digging.
o Misc (4/10)
* Various meetings (usual ones and internal ones)

Port to microinstance - TCWG-432 [2/10]
* More fallout from attempts to fix race condition
* Began cleaning job submission YAML
Controlled image builds - TCWG-360 [1/10]
* (Re)learned how to generate images from hwpack + filesystem
Struck down by flu [7/10]
== This week ==
* Backports (3/10)
- 232493 - Unrelated aarch64 failure and non-thumb asan test on
aarch32 big endian
- 232600 - All tests pass
- 232727 - unrelated non-thumb test failure
asan/deep-thread-stack-1.c asan/deep-thread-stack-1.c)
* Bugzilla 68543 - [AArch64] Implement overflow arithmetic standard
names (3/10)
- Development halted due to submission of related patch by Richard
Henderson:
- https://gcc.gnu.org/ml/gcc-patches/2016-01/txt0WQOxpo0_5.txt
- Began implementation of aarch32 related patch
* Bugzilla 69008 - gcc emits unneeded memory access when passing trivial
structs by value (ARM) (3/10)
- Additional code is being generated in default abi case with
structure alignment equal to 8
- Investigating Dead Store Elimination pass to determine if code can
be improved
* Misc (1/10)
== Next week ==
* Create new bugzilla for aarch32 to implement overflow standard names
and continue implementation
* Bugzilla 69008 - continue investigation
* Work on backports as necessary
== This Week ==
* PR43721 (1/10)
- Submitted upstream.
- GIMPLE parts approved by Richard, wants someone else to approve
rtl-expansion bits.
* benchmarking (1/10)
- benchmarking tcwg-310 on cortex-a53, cortex-a57, r1-a12, cortex-a17
- submitted job for INT benchmarks for SPEC2006 for aarch64
* backports (2/10)
- r232688 automated backport build failed for aarch64-linux-gnu on
tcwg-backport-gerrit:
Unrecognized macro 'GERRIT_PATCHSET_REVISION' in '#664-
${GERRIT_PATCHSET_REVISION,length=8}'
Build successful on tcwg-backport-maxim
- r232737, r232631 have at least 4 dependencies.
- wrote bare bones script to find dependencies for revision
* ccp (2/10)
- enhancement to hoist stmt thru phi with all constant args
- patch: http://people.linaro.org/~prathamesh.kulkarni/ccp-mov.diff
- rejected by Richard, since PRE handles this case when it's
trivially profitable and phiprop does similar transform. In general,
it's not profitable to have this transform included.
* Public Holiday (2/10)
* Misc (2/10)
- Meetings
- Slides: short & long term activities
== Next Week ==
- PR43721: look at using define_expand instead of hook, add test-cases
and few nits
- tcwg-319 - analyse with perf
- LTO INT benchmarking for arm, aarch64 and x86
- LTO Slides
