== Progress ==
* GCC upstream validation:
- a few regressions to bisect. Fixed a minor testcase issue
- native validation in Linaro's lab: we still see a few random results
* GCC
- MVE autovectorization: Working on vcmp.
* Misc
- fixes in stm32 benchmarking harness
== Next ==
* MVE auto-vectorization/intrinsics improvements
* GCC/cortex-M testing improvements & fixes
* cortex-m benchmarking
Holidays next week, back Monday 22nd Feb
Progress:
* UM-2 [QEMU upstream maintainership]
+ sent out a small code-cleanup patchset for some arm display device
models to remove no-longer-needed support for non-32bpp outputs
+ tracked down (with the aid of Paolo) why our build system had started
building the documentation every time you run 'make'; sent a fix
+ code review todo queue status: 12 items, but the oldest was only
sent to the list on Monday...
* QEMU-364 [QEMU support for ARMv8.1-M extensions]
+ An MPS3 Cortex-M55 FPGA image is now publicly available: the AN547.
We'll provide a model of this in QEMU. Started working on the
patchseries to implement it (relatively small changes on top of
the SSE-300 work I've already done but not sent out, and the
mps3-an524 series I sent out for review last week). This is basically
code-complete but I need to do some more testing and ideally I'd
like the AN524 series to get reviewed before I send out another
40-patch series that would have to be based on top of that one.
thanks

Hello,
I've uploaded binaries for Windows on Arm:
081373cc76e88224020fea42eba2161d972f03bb83ebc055fb3cd4f2cfcdfb95
LLVM-12.0.0-rc1-woa64.exe
It was built from the current release/12.x branch (commit b46924ee) with
two patches applied on top:
- https://reviews.llvm.org/D96259
- https://reviews.llvm.org/D96498
It contains "clang;clang-tools-extra;lld;compiler-rt” projects.
Compiler-RT has sanitizers disabled (MEMPROF and XRAY use sanitizer
infrastucture). I.e.,
===
+ -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;lld;compiler-rt" ^
+ -DCOMPILER_RT_BUILD_SANITIZERS=OFF ^
+ -DCOMPILER_RT_BUILD_MEMPROF=OFF ^
+ -DCOMPILER_RT_BUILD_XRAY=OFF ^
===
I've attached the changes we had to make to
llvm/utils/releases/build_llvm_package.bat. @Maxim Kuvyrkov is going to
clean them up and post a patch in the next couple of weeks (he's been doing
all the hard work, I'm just uploading).
This is the first time we're trying to provide a release for Windows on
Arm, so if anyone has any comments or questions, feel free to send an email
:)
Cheers,
Diana

== Progress ==
* GCC upstream validation:
- not really catching up, now ~15 days late due to the numerous
commits. Manually fast-forwarded the latest build to today. I'll
bisect manually for regressions if needed.
- re-enabled native validation in Linaro's lab: we are sending test
results again
* GCC
- MVE autovectorization: vorn patch committed. Working on vcmp.
== Next ==
* MVE auto-vectorization/intrinsics improvements
* GCC/cortex-M testing improvements & fixes
* cortex-m benchmarking
Progress:
* UM-2 [QEMU upstream maintainership]
+ lots of code review this week, including another round of rth's
MTE user-mode patchset
* QEMU-364 [QEMU support for ARMv8.1-M extensions]
+ Sent out an RFC proposing some more Clock API changes (since it'll
be a while before I'm ready to post the series with the new timer
device that requires them)
+ The SSE-200 Cortex-M33-based MPS3 AN524 FPGA image is a useful
target to model: the Zephyr folks would like it, and it is a good
stepping stone to an MPS3 FPGA image with a Cortex-M55/SSE-300 in
it. Wrote a patchset for an mps3-an524 board model, and sent it out
for review.

Progress:
* UM-2 [QEMU upstream maintainership]
+ usual upstream maintenance, code review, etc
* QEMU-364 [QEMU support for ARMv8.1-M extensions]
+ CMSDK Clock changes now upstream
+ When integrating those with the SSE timer model, found what seem like
some more clock API changes we could use; patches in progress
Some Arm-internal training and similar admin tasks this week.
