== 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.

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
thanks

[VIRT-327 # Richard's upstream QEMU work ]
Posted v2 of fixing tlb bswap.
Fixed a regression in arm SMLAL*
Reviewed v2 of risc-v vector extension (ugh).
Created pull for Sven's target/hppa fixes.
[GNU Cauldron]
* Project Ranger: New extensible representation for value ranges.
* Lightning talks, a new gdbserver.
- too short to have enough details to be useful.
- incomplete enough that no demo possible.
- maybe look back at this when it's more developed.
* Register allocation BOF
* ARM BOF
- MTE is alive! In that there are now RFC patches for glibc and gcc.
It's probably time to revive my MTE patch set, at least for system mode.
I spent quite a long time talking with Richard Earnshaw about the
current state of affairs. I'm hoping that we can get the kernel folk
to agree on some fundamentals of the userland ABI, even perhaps before
the final support is in the kernel, so that we can implement the
linux-user side, which would probably be most helpful for glibc+gcc work.
* GCC Steering Committee
* Rethinking GCC development process + continuous testing
* Truly interprocedural IPA-SRA
* Lightning talks,
- EmBench
- Combined elimination for -Os.
* RISC-V BOF

o LLVM:
* Buildbots babysitting:
- Reported a kernel build issue after clang handling of
-march/-mfpu and crypto option was changed.
* Machine Outliner:
- Disabling Thumb1 outlining until we find a better way to handle tailcalls
- Working on Connect slides
o Misc
* Various meetings and discussions.
== Progress ==
* GCC:
- FDPIC: Committed the whole series, expect for one testsuite patch,
pending final review.
* 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 ==
- binutils/linker support for non-contiguous memory regions
- FDPIC: work on gdb
- GCC upstream validation: Add a config for cortex-m33 (v8-m)
LLVM-579 Implement -fix-cortex-a8 in LLD. Keeping up with review
comments, I think this is getting close now.
Connect slides moving forwards. Now have 2 out of 3 presenters done.
Rest of the week taken up by investigations and LLD reviews.
Progress:
* VIRT-65 [QEMU upstream maintainership]
+ implemented and sent patchset for semihosting v2 API
+ target-arm pullreq, patch review, etc
+ got the QEMU Summit invite list finalised and sent invites
+ some internal meetings
thanks
