Hi Richard,
Your patch below ICEs on aarch64-linux-gnu. Should reproduce easily on native or cross aarch64-linux-gnu build.
Let me know if you need any assistance in reproducing this.
Thanks,

Hi Manos,
New tests in your patch [1] fail on aarch64-linux-gnu build in our CI. Would you please investigate why? Testing logs are at [2].

Hello,
# [GNU-767] Support changing SVE vector length in remote debugging
- Continued working on new approach to support changing SVE vector
length in remote debugging.
# TCWG CI
- Analysed GCC regression GNU-880 which is actually an XFAIL → XPASS so
I sent a patch removing the xfail annotation.
- Analysed GCC regression GNU-881. The problem is that we don't have
Python in the ABE sysroot so a new Python GCC plugin testcase fails to
build. Sent a patch to detect that situation and mark the test as
unsupported. It was committed upstream.
- Tested a couple of new versions of a GDB mailing list patch to see if
it fixed the failure reported by the precommit CI. Reported results to
patch author.
- Fixed silly mistake spotted by Laurent in ABE Gerrit requests to use
TIMEOUTFACTOR for DejaGnu testsuites. Adjusted it to not use the
factor in GDB on armhf and sent new version for review.
- Reviewed a couple of Gerrit requests.

Thiago
Progress (short week, 3 days):
* UM-2 [QEMU upstream maintainership]
- sent out another couple of "avoid VLA" patches
* QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG]
- managed to write some first-pass code for the MTE checks for
FEAT_MOPS memset operations. Got something together enough to
send to RTH for some pre-review before I roll the approach out
to the other insns.
-- PMM
Hello,
# [GNU-767] Support changing SVE vector length in remote debugging
- Returned to implementing support for changing SVE vector length in
remote debugging. The patch series I sent earlier this year used an
approach that some maintainers weren't enthusiastic about (modifying
the Remote Serial Protocol to request XML target descriptions). Now
trying the approach they suggested, which is to extend target
descriptions to support expressing vector registers whose length is
given by the contents of another register.
# TCWG CI
- Following Maxim's suggestion, sent and merged Gerrit review requests
to increase chance of tcwg_gdb_check jobs to be faster at detecting
new or newly expired flaky tests:
- 45151: tcwg_gdb: Increase job frequency
- 45152: round-robin.sh (build_abe): Increase time to re-detect GDB
flaky tests
- Implemented change in ABE to support glibc's TIMEOUTFACTOR environment
variable for DejaGnu testsuites. Testing on armv8l and aarch64.

Progress:
* UM-2 [QEMU upstream maintainership]
- code review, notably:
+ RTH's setnegcond series
+ Jean-Philippe's fixes for various FEAT_RME bugs
+ Akihiko's series to make KVM '-machine none' not default to 40 bits
of IPA space if the host doesn't supoprt that (like the Apple CPUs)
- sent a patch to catch the illegal exception return case from
EL3 with bad SCR_EL3.{NSE,NS}
- respin and resend of ptw cleanup patchset
- tidied another 'BiteSizedTask' entry into a gitlab issue
- went back to an old minor cleanup task: getting rid of the
last dozen or so uses of variable-length arrays in the codebase
(so we can enforce not using them in the compiler, and avoid
unchecked-on-stack-allocation security bugs). Sent patches to
zap a few more.
* QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG]
- thinking a bit more about FEAT_MOPS and MTE checks, but ultimately
not much progress: didn't find enough hours with a sufficiently
alert mind...
-- PMM
Hello,
# TCWG CI
- Implemented increasing testsuite timeout for each testsuite try in GDB
check jobs. Sent a Gerrit review request for it but then found out that
it makes armhf jobs take a lot longer, so abandoned it.
# Community
- Finished reviewing SME patches for GDB and gdbserver.

Thiago
Progress:
* UM-2 [QEMU upstream maintainership]
- some bits and pieces for release
- code review, notably:
+ raspberry pi 4 support patchseries (a big 44-patch set)
+ Xilinx Versal CFI support patches
* QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG]
- more work on FEAT_MOPS: tested my memset implementation, and
fixed various bugs. Still no MTE tag checking support.
-- PMM
Hello,
# TCWG CI
- CI Babysitting: Worked on two regressions detected at the end of last
week.
- Enabled precommit testing for GDB patches.
# Misc
- Reviewing SME patches for GDB and gdbserver.

Thiago
Progress:
* UM-2 [QEMU upstream maintainership]
- release related stuff: handling merge requests, etc (now passed
back to RTH again)
- sent some patches for a few easy coverity issues
- worked through some code review (in particular some patches
from new contributors)
- created a gitlab "bite sized task" issue that better explains
and has more detail on the "convert from malloc to g_malloc"
suggested task for new contributors
* QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG]
- a little more progress with FEAT_MOPS. I now have an untested
implementation of the memset insns which I think is complete
except for MTE tag checking
-- PMM
Hello,
# TCWG CI
- Babysat the CI: Investigated 9 regressions in GCC, 2 in GDB, 1 in LLVM
and 1 in glibc. Reported 4 in GCC (GNU-855, GNU-857, GNU-858 and
GNU-859). 3 of which are fixed and another has a tentative fix.
- Reviewed a couple of Gerrit requests.

Thiago
Progress:
* UM-2 [QEMU upstream maintainership]
- fixed some places in our RTC device models where we were
putting a time_t or time_t offset into a 32-bit variable
- took over from RTH briefly for pullreq merge handling
- sent some patches fixing minor Coverity issues
- investigated a couple of "test case fails on big-endian host"
errors: sent patches for Sparc FPRS handling and for
the Arm SMMUv3 model
- Investigated report that our MPS2/3 M-profile models don't
have the same number of MPU regions configured as the real FPGA
images, and so you can't run the same Zephyr binary on both.
Have some preliminary patches to correct the number of regions.
* QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG]
- finally got back to FEAT_MOPS work; wrote a skeleton of code
for the memset operations that's about right up to the point
where it needs to actually do the memset...

Hi everyone,
I'm not 100% sure whether this is a bot misconfiguration issue, but couldn't find any other source of this failure:
```
******************** TEST 'test-suite :: MultiSource/Applications/ClamAV/clamscan.test' FAILED ********************
Executable '/home/tcwg-buildbot/worker/clang-aarch64-sve-vla/test/sandbox/build/MultiSource/Applications/ClamAV/clamscan' is missing
********************
```
Link: https://lab.llvm.org/buildbot/#/builders/197/builds/8209
Would anyone be able to take a look?
Thank you :)

Progress:
* UM-2 [QEMU upstream maintainership]
- investigated and fixed a bug in page-table-walk handling of
debug accesses that was introduced by the FEAT_RME changes
- that prompted me to look at a cleanup of some of the ptw code
so that we consistently look at "which space is this walk for"
and don't carry around a parallel boolean "secure/non-secure"
that duplicates that information
- found and fixed a few other ptw bugs along the way
-- PMM
Hello,
# TCWG CI
- Changed tcwg_gnu-build.sh to apply GDB patch adding
'--with-additional-debug-dirs' option, and ABE's gdb.conf to use it.
Also changed both to add '--prefix /usr' option to GDB's configure.
Both changes to fix ld.so debug info issues in GDB testsuite runs on
armhf.
- Testing changes to validate_failures.py and jenkins-scripts to handle
empty gdb.sum.
- Reviewed a few Gerrit requests.

Progress (short week, 3 days):
* UM-2 [QEMU upstream maintainership]
- softfreeze is next week, so spent some time putting together
a pull request, fixing the bugs which the CI tests found in
it, etc
* QEMU-422 [QEMU Arm Neoverse V1 vCPU for TCG]
- now that we implement all the necessary features (excluding
some trace/profiling type stuff that is out-of-scope for
QEMU, and also FEAT_NV that we might come back to later), sent
out the patchset to define a 'neoverse-v1' CPU type for QEMU
