== Progress ==
* GCC upstream validation:
- reported several regressions/new failures
* GCC
- Neon intrinsics: vceqq, vceqz and vceqzq for p64 patch: no feedback
- MVE autovectorization: committed vand and vorr patches. Sent updated
versions of veor, vbic and vmvn. vshr and vshl need some
refactorization with Neon versions, clarified the best way to go with
Arm maintainers.
- PR97875 (suboptimal vectorization on MVE): investigation shows that
movmisalign patterns are missing for MVE.
* benchmarking:
- Scripts to run coremark on stm32 now merged, debugging issues. No
progress this week.
* infra:
- debugging issues with our docker containers
- looking at ABE patches
* misc:
- provided feedback to Arm's partner wrt Intrinsics documentation
== Next ==
* GCC/cortex-M testing improvements & fixes
* cortex-m benchmarking
* MVE auto-vectorization/intrinsics improvements
[UM-59]
More work on softfloat rem; f128 still needs work.
[UM-2]
Patch review, notably v8.1m, mips cleanups, arc port.
Revisions to arm alignment patch set.

== This Week ==
* PR97872 (missed optimization on less-than vector comparison)
- Upstream discussion with Richard, patch close to being approved.
- Causes a regression for pr78102.c.
* PR66791 (replace builtins by vector extensions in arm_neon.h intrinsics)
- Submitted patches for vmvn, vcreate, vneg.
- Kyrill approved patch for vmvn, and asked to remove corresponding builtins
from being created in backend.
== Next Week ==
- Hopefully commit fix for PR97872
- Continue with PR66791
- Start looking at another vectorization PR

Progress:
* UM-2 [QEMU upstream maintainership]
+ Cut down the patch review queue a bit ready for 6.0 development cycle
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ started working on modelling of the SSE-300. Have done some of the easy
"ID registers are different" stuff and started on modelling a new timer
device that isn't in the SSE-200.
thanks
