Progress (short week, 3 days):
* UM-2 [QEMU upstream maintainership]
+ Code review:
- reviewed the easy half of the "aarch64 support for osx hvf accelerator"
patchseries
- RTH's bfloat16 support series
+ Misc bugs:
- Sent a patchset fixing a compile failure reported by MS when the
'virt' board is not enabled (requires a custom local config)
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
+ Working through the details of how PSR.ECI works for resuming
half-executed insns (annoyingly awkward to implement for a subfeature
that will almost never get used...). I have most of an implementation
now but it needs a bit of new functionality in TCG ("throw away any
TCG ops we just generated and rewind to point X") which RTH hasn't
written yet :-)
+ None of that work corresponds to adding more insn patterns, so no
change on the Progress meter: 73/210 (34%)

Progress (short week, 3 days):
* UM-2 [QEMU upstream maintainership]
+ Code review:
- SVE2 series v7 (now finally done)
- RTH's tlb_flush range refactoring
- A few other minor patchsets
+ Arm pullrequest: SVE2 emulation support is now upstream
+ Misc bugs:
- sent some patches fixing a few coverity nits in our test suite code
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
+ Implemented:
- VQDMULL, VRHADD, VADC, VSBC, VCADD, VHCADD
- LCTP, LETP, WLSTP, DLSTP (the tail-predicating loop insns)
- Progress meter: 73/210 (34%)
-- PMM
== This Week ==
* PR66791 (Replace builtins with C operations in intrinsics)
- vtst: Committed patch to trunk.
- vshl_n: Patch results in worse code-gen, abandoned.
- vmul_n: Created patch, looking into testsuite fallout
* PR97906 (Missed lowering abs(x) >= abs(y) to vcage x, y)
- Investigated PR and have a WIP fix.
== Next Week ==
- Continue with PR66791, PR97906
Progress:
* UM-2 [QEMU upstream maintainership]
+ Code review:
- bfloat16 support patchset
- v3 of ITS emulation patchset
+ Misc bugs:
- sent a patch fixing a bug where we sometimes selected the wrong stack
pointer when doing a v8M exception return in a case involving
tail-chaining (needed by an upcoming Arm TF-M change)
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
+ Sent a small patchset which implements a few preliminary MVE things
(VPR register, FPSCR.QC bit, fixing checks for existing insns which
now need to be "FP or MVE" rather than just "FP")
+ Implemented:
- VADD VSUB VMULL VHADD VHSUB VQADD VQSUB VQDMULH VQRDMULH scalar
- VBRSR, VPST, VQDMULH, VQRDMULH, VQADD, VQSUB
- VQSHL VQRSHL VSHL VRSHL vector forms
- VQDMLADH, VQRDMLADH, VQDMLSDH, VQRDMLSDH
