== Progress ==
* spec2k comparison between ARM and x86
- Specfp on x86 has some failures in trunk
- Trying 4.8 now
- Analysed some of the benchmarks and documenting them
- continuing with the rest.
== Plan ==
* Continue with spec2k comparison between ARM and x86
== Issues ==
* None
== Progress ==
* Investigate big endian toolchain build in Linaro crosstool-ng.
- Fix an aarch64 triple name issue.
- Add Linaro armeb-linux-gnueabihf, aarch64_be-linux-gnu and
aarch64_be-none-elf configs for big endian builds.
- Please find the reference builds at:
http://cbuild.validation.linaro.org/build/crosstool-ng-linaro-1.13.1+bzr258…
* Design a test case for lp1189445 and revise the patch for review.
* Revise the shrink-wrap related fix for pr57637 and send out for review.
* Investigate lp:1194501 and lP:1194123
- lp:1194501 is confirmed a "tail call" issue, and also in trunk pr57731.
- lP:1194123 seams shrink-wrap related, since the case pass with
option -fno-shrink-wrap.
== Plan ==
* Continue on conditional compare.

== Progress ==
* Divmod patch
- Trying to regain knowledge about the SelectionDAG infrastructure
- Working with Tim and Joey, got a patch working, but seen some failures
in test-suite
- Will investigate and submit when all is clear
* Lencod in LNT
- Bug is a mix of ByVal with wrong spill offset, teams interacting
- Bug fixed by a side effect of another change, can't guarantee future
stability
* CBuild
- Patch merged, fired another LLVM benchmark, which failed the same way
- Not sure how to proceed here...
- Should I dig deep on the old CBuild?
- Or should I wait for CBuild2?
* Release Maintenance
- Talks about maintenance of old/current releases sparking on the list
- Bots, tests, benchmarks, release process will have to be followed for
those releases
- Binary & API compatibility kept, performance doesn't matter much, only
serious bugs fixed
- This will increase the cost of background duty on our team
* Other
- Reviewing some more patches
- Checking impact of a new alias analysis in the loop vectorizer, all good
- EuroLLVM 2014 meeting
- Long discussions about pre-UAL support in LLVM: Short answer: no.
- Someone else will look at PerfDB analysis, one less thing to do
- Got the Buildbot Pandas home, will look at them next week
== Issues ==
* After using all my RAM all the time, for a week, I found a fault on it
which prompted kernel panic and stopped my laptop from booting. Luckily, it
was just one of the two chips, and even better, it has a lifetime
guarantee! But I'll only get a new one after Connect... :(
== Plan ==
* Finish implementation AEABI divmod/udivmod calls
* Carefully analyse what's the best configuration for the pandas and
produce a pre-packed image
* NOT put them back before they're stable, snapshot a known good
configuration
* But put TWO pandas as self-hosting (and leave Galina's alone)
Time allowing...
* Check why Phoronix result pages are not working
* Write about target-specific tests on TestingGuide.rst
* Write a thing or two about the optimization levels in LLVM for the
official docs
== Progress ==
* Some further work on AArch64 ifunc failure, no progress.
* Add some extra features to cortex-strings plotting capability.
* More memcpy gerrit review.
* Basic framework for testing and benchmarking malloc.
* Extracted glibc malloc from glibc.
* Pushed memcpy performance tweak to cortex-strings and newlib for review.
== Issues ==
* None.
== Plan ==
* Prepare for Connect.
* Resubmit memcpy to gerrit as requested.
* Respin AArch64 ifunc patches against latest head.

Progress:
* VIRT-49 closed out (cp15 migration patches committed upstream)
* virtio:
** virtio-mmio patchset v1 now sent out to qemu-devel
* misc:
** fixed some instances of undefined behaviour (mostly shift related)
diagnosed by clang -fsanitize=undefined
** worked through upstream review backlog, sent target-arm and arm-devs
pullreqs
Plans:
* VirtualOpenSystems (sponsored by Huawei) have sent a patchset for
KVM support in QEMU for ARMv8; need to review this and reconcile it
with the Linaro work in progress in this area
* mach-virt
