Controlled image builds - TCWG-360 [2/10]
* A few more test/debug cycles with ci-loop-built image
Jenkins benchmarking job - TCWG-348 [3/10]
* YAML-ised Jenkins job, more test/debug cycles
Juno crashdump [1/10]

SPEC-on-Android [1/10]
* Looked at Qian's work to date, didn't come up with any bright ideas
Misc [3/10]
=Plan=
Review security with shared uinstance/main instance code
Expose more data, benchmarks to bundles
Continue debug/test of Jenkins job
Create bootable image for at least 1 target, or know what the problems are
Write up noise control report (if time)
Set Juno off, try to get a dump of my crash
Probably more support for SPEC-on-Android

'ARM Day' next Monday (30th)
== This week ==
* TCWG-317 - Exploit wide add operations when appropriate for Aarch32 (5/10)
- Blocked as I have not yet determined why the pattern fails on big
endian targets
* TCWG-369 - Exploit wide add operations when appropriate for Aarch64 (1/10)
- Modified code based on minor code style comments
* TCWG-316 - Exploit vector multiply by scalar instructions (3/10)
- Discovered relevant previous RFC:
https://gcc.gnu.org/ml/gcc/2013-09/msg00061.html
- Coded subset of vector patterns
- Debugging combine phase to determine why patterns are not
being utilized
* Misc (1/10)
- Conference calls
== Next week ==
- TCWG-369 - Submit modified patch upstream for final approval
- TCWG-316 - Determine if rtl patterns can be used by combine
- TCWG-317 - Need feedback
- USA Thanksgiving Holidays (November 26-27)
== This Week ==
* TCWG-72 (2/10)
- Rebased patch
- Fixed ICE for x86-gcc with -m32 following Jim's suggestions.
* Target hook conversion (6/10)
- Converted ASM_FORMAT_PRIVATE_NAME, ASM_LABEL_OUTPUT_LABEL,
ASM_OUTPUT_LABELREF to hook
* TCWG-319 (1/10)
- Benchmark jobs for fp in progress on a53, a57.
* Misc (1/10)
- Meetings
== Next Week ==
- Test and send updated patch upstream for tcwg-72
- TCWG-319 benchmarking on cortex-a15
- Holidays from 23-25th November (Mon-Wed).
# Progress #
* TCWG-332, done. [1/10]
Fix GDB bug on stepping over breakpoint on ARM. Patch is pushed in.
* TCWG-423, patches are posted. [5/10].
Support gnu vector in inferior call in AArch64 GDB.
Also correctly handle HVA (homogeneous vector aggregate) in inferior
call.
* TCWG-433, done. [2/10]
All memory issues found by -fsanitize=address in GDB are fixed.
* TCWG-447, done. [1/10]
Fix GDB mainline build warnings and errors in C++ mode on ARM and
AArch64.
* Discussion on the approach of building GDB in C++. Need to test GDB
built in C++ on both ARM and AArch64, from my side. [1/10]
# Plan #
* Understand ST's jtag probe and help them to make use of multi-arch
in GDB.
* Fix GDB internal error in gdb.thread/watchpoint-fork.exp on AArch64.
* TCWG-156, GDB test parity between AArch64 and X86_64.

== Progress ==
* Validation (6/10)
- a few improvements in the validations using the ST compute farm
- thinking about appropriate ways of sharing validation
reports with the GCC community without flooding gcc-testresults
- moved results comparison scripts to a dedicated repo
and updated Jenkins jobs accordingly
* GCC (1/10)
- bug #1869 / glibc dependency on RHEL6
proof of concept to force use of old memcpy
but it will be much safer to build the toolchain
in a suitable container with the right distro
* Misc (conf calls, meetings, emails, ...) (3/10)
- patches and backports reviews
== Next ==
* Validation
- continue preparation of switch, as dev-01 is now back
- improve reporting
* GCC:
- check Neon tests cleanup
- bug #1869
- look at how to send valuable reports to gcc-regression
Hi,
We're currently running into issues with the OE builds due to OE-core
having moved to 2.22. So what's the plan for glibc-linaro 2.22?

Hi,
This question has arisen in the ODP project and the thought is that a 'best
practices' answer would be more likely to be found on this list.
We have a component that wants to make use of specialized instructions for
performing CRC and/or AES computations and was wondering what is the
recommended way for an application to determine whether such instructions
are available in the toolchain and whether the user has overruled their use?
Thanks for any insight you can provide.
Bill
