[VIRT-327 # Richard's upstream QEMU work ]
Misc patch review.
[GCC]
I looked into Adhemerval's libgomp-scalability patch set. The code looks good,
and I can't see anything wrong.
The cancel-parallel-2 test that's reported to regress, does, sometimes. It
never fails for me on qemu-test (aarch64, tx1). It *only* fails under the
dejagnu test harness on x86_64 and ppc64le. When run by hand it succeeds,
always. I cannot explain that at all. I've run the testsuite with
OMP_DEBUG_ENV=verbose and see that the dejagnu environment is as expected.
Anyway, I can't make forward progress because I can't reproduce the problem
under controlled conditions.

Progress:
* VIRT-65 [QEMU upstream maintainership]
+ More wrangling of release stuff and unreliable infrastructure.
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ Managed to find a few days to put in some more work pushing fp16
handling forwards. I now have implementations of fp16 for most of
the VFP insns (still todo: VCVT, VSEL, VMAXNM/VMINNM, VRINT*; then
the few insns that are new-for-fp16. Then all of Neon, which is larger.)
thanks

Progress:
* VIRT-65 [QEMU upstream maintainership]
+ softfreeze this week, so a lot of handling of pull requests,
reviewing various patchsets, sorting through newly reported
Coverity issues, etc etc.
thanks
-- PMM
== Progress ==
* GCC upstream validation:
- reported a few regressions / minor testcase fix
- enabled gcc-testresults for release branches, which will send even more emails
* benchmarking:
- added HAL support for the stm32 board we have in the Lab. Will start
testing once the board is actually connected to a builder
* misc:
- infra patches/reviews
== Next ==
* Holidays next two weeks, back on July 28th
* GCC/cortex-M testing improvements & fixes
* cortex-m benchmarking
