On buildbot duty
- Several buildbot failures to investigate along with one linux kernel
regression
- Didn't manage to get the libcxx buildbot failures resolved on time.
I think the community are still trying to fix it (Script needs to be
Python2/Python3
Started work on LLD support for Morello
- Getting familiar with the toolchain
- First target is sufficient support to statically link the Howdy
"hello world" equivalent.
- Made the first couple of local patches to implement the easiest set
of static relocations.
Some upstream LLD patch review.
Progress:
* VIRT-65 [QEMU upstream maintainership]
+ investigated the cause of a hang when using single-threaded TCG
+ sent RFC patchset proposing a rework of the ptimer API/implementation
which will fix LP:1777777. Unfortunately we'll need to update all
the devices using ptimers. I started in on that process of conversion,
which turns out to be a little more awkward than I had expected;
I ran into at least one corner case I hadn't thought about.
thanks

== Progress ==
* Out of office on Monday
* Catching up after Connect
* Minor buildbot fix
* IR SVE Reviews [LLVM-545]
- Another round on the size queries patch
* SVE IR fuzzer [LLVM-586]
- Waiting for the size queries patch to get merged so I can give it a spin
* Support Arran fat pointers in LLDB [LLVM-597]
- Built lldb
- Looked a bit through the docs
== Plan ==
* Play more with lldb, read more docs
* A bit of globalisel maintenance
o LLVM:
* Buildbots babysitting:
- Troubleshot ARMv8 selfhosted bots issue
* Machine Outliner:
- Experiment outlining with -mexecute-only
- Tried to find a testcase which exhibits issues with unwinding
without much success.
o Misc
* Various meetings and discussions.
Progress:
* VIRT-65 [QEMU upstream maintainership]
+ identified cause of LP:1844597 and sent patch fixing it (we broke
direct-booting kernels when the emulated system has an AArch32 EL3)
+ tracked down the cause of LP:1777777 to a race condition that's
inherent to the current design of QEMU's 'ptimer' countdown timers;
fixing this will require us to rethink when we call the callback
when a ptimer hits 0. Posted some ideas to mailing list, for feedback
on whether I missed a better way to rework them.
+ usual upstream maintainer stuff; managed one way or another to
get a few of the most obstinately sticky patchsets off my to-review list
thanks

== Progress ==
* GCC:
- FDPIC: Whole series now committed. Reverted one patch (aiming at
cortex-M, caused problems in ARM mode, investigating)
* GCC upstream validation:
- reported a couple of issues. Helped with testing.
- getting ready to add cortex-m33 validation with qemu
* Binutils:
- Non-contiguous memory regions support in the BFD linker: not started yet.
* misc:
- infra fixes / troubleshooting / reviews
== Next ==
Linaro Connect San Diego
== Progress ==
* Out of office on Friday
* Use newer perf for benchmarking [TCWG-1512]
- Switched benchmarking to use bionic containers, with perf 4.18.0;
seems to work
* Investigate running benchmarks in containers [TCWG-1513]
- Done
* Uploaded LLVM 9.0.0-rc5 and rc6
* SVE IR fuzzer [LLVM-586]
- Unblocked my work on this, need to give it a serious spin
== Plan ==
* Buildbot babysitting this week
* LLVM-586
* Try to build LLDB
[VIRT-327 # Richard's upstream QEMU work ]
Convert notdirty and rom handling to cputlb; lots of cleanup around
that area. Version 3 is the first version that worked; two previous
RFCs took quite a bit of effort to work out why they didn't work.
[GCC]
Committed the lse out-of-line patch set.
Posted patches for two follow-on bugs affecting aarch64-elf.
r~
Progress:
* VIRT-65 [QEMU upstream maintainership]
+ sent v2 of the semihosting v2 API implementation patchset
+ sent patch to fix a Makefile bug I introduced that broke in-tree builds
+ code review etc
