- Intel CET review (Related to BTI support in LLD), raised issue of
multiple PT_NOTE sections one per alignment
https://reviews.llvm.org/D59120 , commented on command line options.
- LLVM-523 redesigned the LLD handling of ARM exidx sections to
centralise more of the Arm specific implementation details in one
place. Hope to post upstream to get some movement on the review to add
missing .ARM.exidx sections for chrome OS team.
- LLVM-542 Managed to build most of the Zephyr examples for clang,
shared patches to do so with zephyr tech lead.
- Some research for some ABI topics.
- Some thoughts for Linaro connect activities, started team calendar.
Next week:
- Start on my connect presentation
o LLVM
* Machine outliner:
- Stack alignment and refactoring.
- Start to prepare BKK19 talk
* Bots babysitting
* Built 8.0.0-rc4 binaries for x86 and ARM, got issues to start the job on D05
o Misc
* Completed BKK19 and EuroLLVM trips.
* Various meetings and discussions.
== Progress ==
* FDPIC
- (GNU-411) GDB: debugging problems with FDPIC support. Working on
setup of an stm32 board.
* GCC upstream validation:
- reported a few regressions
* GCC:
- (GNU-99) ubsan / bare-metal. No progress.
* misc (conf-calls, meetings, emails, ....)
- reviewing infra script patches
- debugging new benchmarking round-robin jobs
== Next ==
FDPIC:
- GCC: handle feedback on v4 patches
- GDB: update patches
- uclibc-ng: look at how to test fdpic mode with openadk
- complete board setup
Infra:
- benchmarking jobs
- add QEMU to list of components built by ABE

Forward
Progress:
* VIRT-65 [QEMU upstream maintainership]
+ code review
- add watchdog device to stellaris boards
- bcm2836 "local timer" device
- RTH's rolled-up patchset for SB, PredInv, CondM, FRINT extensions
- Eric's patchset to allow the 'virt' board to have more than 255GB of RAM
- a patchset to add a "generic nommu" board for NiosII
+ assembled a target-arm pull request for softfreeze
+ fixed some minor issues with the "build sphinx docs" patches,
and got them into master (and then fixed some more minor issues...)
* VIRT-268 [QEMU support for dual-core Cortex-M Musca board]
+ progress on M-profile floating point:
- finished first draft of changes to exception handling code
- this is now on hold as we are into softfreeze for QEMU 4.0 and other
work for that release will take priority for the next few weeks
thanks

- Committed patch to abe to enable bootstrap implicitly when buildconfig is set.
- Started tracking for tcwg_gnu ci job (init_configuration == false).
* Public holiday (2/10)
* Misc (1/10)
- Meetings
== Next Week ==
- Continue ongoing tasks
o LLVM
* Back to machine outliner after vacation
- Rebased on upstream master branch
- Working on stack alignment and refactoring.
o Misc
* Preparing BKK19 and EuroLLVM trips.
* Various meetings and discussions.
* PR88838
- I have a patch which solves this.
* adds iv in Pmode but compare_type in 32bit
- It exposes a latent bug in fwprop in regression testing
- Looking into it
== Plan ==
* Complete above PRs
* Look at GDB BZ #21221 - gdb hangs while stepping an empty loop
Progress:
[VIRT-274 # ARMv8.2-FHM, Floating-point multiplication variant ]
Now upstream.
[VIRT-298 # ARMv8.4-CondM, Condition flag manipulation ]
[VIRT-329 # ARMv8.5-CondM, Condition flag manipulation ]
[VIRT-337 # ARMv8.0-SB, Speculation Barrier ]
[VIRT-338 # ARMv8.0-PredInv, Prediction Invalidation ]
[VIRT-330 # ARMv8.5-FRINT, Floating-point to integer ]
Posted an omnibus of SB+PredInv+CondM+FRINT that I have
labeled "v3", as 3 > any individual revision previously used.
[VIRT-327 # Richard's upstream QEMU work ]
Reviewed s390x vector patch set v2.
Implemented pattern groups in decodetree.
Prototyped A32 conversion to decodetree;
started a second revision that incorporates T32.
Started looking at
https://bugs.linaro.org/show_bug.cgi?id=4274
I can swizzle things around by changing the group name from
"cp_regs" to the predefined "system", but somehow those regs
are *also* registered with "general". Which means the
undesired behaviour by which "info regs" prints all of the
system registers still exists.
