Hi
I've been trying to run clang on a Windows on Arm machine, but it keeps trying to using the link.exe located in "Visual studio/..../Host64/arm64", which is (seemingly) an x64 tool and as such doesn't run, and crashes the process.
Is there a way to set clang to look at VS's x86 link.exe? Or if there is an arm64 version that clang should be using instead?
Thanks,
Joel

Hi,
I've been trying to use clang on Windows on Arm machine (Samsung Galaxy Book S), but whenever I try to use it, I get either nothing (in powershell) or an error popup: "The application was unable to start correctly (0x000007b)".
The release I'm using is LLVM-12.0.0-rc1-woa64.exe<https://github.com/llvm/llvm-project/releases/download/llvmorg-12.0.0-rc1/L…> from https://github.com/llvm/llvm-project/releases/tag/llvmorg-12.0.0-rc1
I have a feeling there might be a library or dependency I am missing.
Any help with how to resolve this issue would be appreciated.
Thanks,
Joel

[UM-2 # QEMU Upstream Work]
* A lot of patch review.
* Some target/i386 cleanup, as followup to said patch review.
* Collecting patches for tcg-next.
r~
== Progress ==
* GCC upstream validation:
- a few regressions to bisect. Fixed a minor testcase issue
* GCC
- MVE autovectorization: Working on vcmp. After some cleanup &
factorization, the cmp operators work on GCC vectors. I will now
resume work on auto-vectorization.
* Misc
- fixes in stm32 benchmarking harness
== Next ==
* MVE auto-vectorization/intrinsics improvements
* GCC/cortex-M testing improvements & fixes
* cortex-m benchmarking
* After proving that the aarch64 host problem with
booting s390x with virtio was lack of barriers for
the guest memory model, I've spent some time working
on a ld-acq/st-rel optimizer for tcg.
* Minor rev of tci rewrite.
* Some patch review on claudio's kvm/tcg split.

Progress:
* QEMU-364 [QEMU support for ARMv8.1-M extensions]
+ sent out v2 of the MPS3-AN524 series (minor changes only)
+ discovered that I need to implement the SSE-300's System Counter
+ implemented the system counter, did some final testing and
reviewing, and sent out v1 of the MPS3-AN547 series to the list
+ once these patches are reviewed and in master the QEMU-413 epic
will be complete

Hello Linaro Toolchain Working Group,
libcxx-libcxxabi-libunwind-armv8-linux has been red for 5 days.
clang-cmake-aarch64-global-isel has been red for 10 days.
clang-cmake-aarch64-quick has been red for 10 days.
clang-cmake-armv7-global-isel has been red for 10 days.
clang-cmake-armv7-lnt has been red for 10 days.
clang-cmake-aarch64-lld has been red for 11 days.
clang-cmake-armv8-lld has been red for 11 days.
clang-cmake-thumbv7-full-sh has been red for 11 days.
clang-cmake-armv7-full has been red for 11 days.
Is anybody looking at this?
I also noticed that some of your workers are less reliable than others. For
example, inaro-tk1-09 worker was last time producing a green build 2 months
ago - http://lab.llvm.org:8011/#/workers/2?numbuilds=500
I'm removing the linaro-tk1-09 worker from the production buildbot for now.
Please feel free to connect it to the staging and make the builder reliably
green. Then it could be returned back to the production.
linaro-armv8-windows-msvc-01 and linaro-armv8-windows-msvc-02 have been red
for the least 4 months. I'm removing them from the production buildbot. You
can return them back to production after they are reliably green in the
staging.
Please feel free to ask if you have questions.
Thanks

- a few regressions to bisect. Fixed a minor testcase issue

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.
