Progress:
* VIRT-65 [QEMU upstream maintainership]
+ lots of code review and other work for softfreeze
+ tracked down the bug that caused regressions running UEFI in a
KVM guest with commit 823e1b3818f9b1, and sent out a fix
thanks
-- PMM
== Progress ==
* FDPIC
- Setting up new stm32f429-disc1 board. Boots OK with buildroot's
default 4.11 kernel. Boot seems to fail starting with 4.13 (recent
kernel needed to have FDPIC support)
* GCC upstream validation:
- reported a few regressions
* GCC:
- (GNU-99) ubsan / bare-metal. No progress.
* misc (conf-calls, meetings, emails, ....)
- reviewing infra script patches
- adding qemu as a toolchain component supported by ABE. A bit
convoluted because of manifest handling.
== 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
== Progress ==
* Out of office 1 day (Thursday)
* [Thumb GlobalISel] Bugfixes [LLVM-544]
- The test-suite compiles and executes without failures (with
fallback to DAG ISel)
- We get some bus errors in the selfhost, which are due to unaligned
64-bit stores. Apparently when alignment checks were introduced in the
legalizer, they were only used for types < 32 bits. Currently testing
a patch to fix this oversight.
* LLVM 8.0.0 Release for ARM & AArch64 [LLVM-526]
- rc5 looks good on AArch64, ARM is still in progress (waited for LSS-570)
== Plan ==
* Wrap up LLVM-544
* Upload rc5 when ARM is ready
[VIRT-344 # ARMv8.5-MemTag, Memory Tagging Extension ]
Posted v4, with system mode only.
[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 ]
All upstream.
[VIRT-327 # Richard's upstream QEMU work ]
Reviewed s390x vector patch set 3.
Reviewed renesas rx patch set 3.
Posted some patches and thoughts for
https://bugs.linaro.org/show_bug.cgi?id=4274
Implemented extract2 as a tcg opcode.
Minor hppa bug fixes.
Lots more work on decodetree and A32+T32+T16 conversion.
r~
- 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

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
