== Progress ==
* FDPIC
- Cortex-M uClibc-ng patch still pending
- GCC: handling feedback on v3 patches.
  Managed to build/check xtensa uclinux toolchain with my patches.
Largely better, but a few new failures.
- working on kernel + qemu-system env to run more tests. Got help from
Nicolas Pitre.

* GCC upstream validation:
- reported a few regressions
- dealing with some random results, again

* GCC:
- bug report on aarch64 about misaligned accesses. Waiting for more
details to reproduce the problem.

* misc (conf-calls, meetings, emails, )
- reviewing infra script patches

== Next ==
FDPIC:
- GCC: followup v3 patches
- uclibc-ng: look at how to test fdpic mode with openadk
- use qemu-system mode to run more tests

[ACTIVITY] report week ending 9 Nov

2018-11-09 Thread Peter Maydell 
Progress:
 * VIRT-65 [QEMU upstream maintainership]
  - code review
   + more microbit device models
   + some raspi device model improvements
  - sent patches for more Coverity issue fixes
  - put together a list of source files still with legacy
non-QOM device models (about 60 files total)
  - tagged QEMU 3.1.0 rc0
 * VIRT-251 [aarch32 Hyp/running microvisors]
  - tracked down a regression affecting L4Re guest: we had
misimplemented HCR.{VI,VF}. Sent patchset reverting the
broken version and implementing the correct semantics.
  - finally tracked down why the 32-bit version of L4Re/Fiasco was
crashing -- we were incorrectly implementing Hyp mode as having
a banked r14, but it shares that register with User and System modes.
  - These patches fix all the known issues with these guests.

thanks

[LLVM-203] Using PGO for code size optimization
Communicated results and shared patch with Google Android/ChromeOs and
Fuchsia teams

[LLD] Did some benchmarking of LLD against ld.bfd and ld.gold
On some large applications like Mozilla and Chrome LLD can be up to 10
times faster.
