* preparation for Connect
* wrote up and sent out proposal about handling TrustZone for KVM
* investigated some issues Riku found when testing his packaged
version of KVM (one model issue, one kernel-too-old issue)
* usual upstream maintainer duties

Hi,
OpenEmbedded-Core/meta-linaro:
* cbuild enhancements:
* debugged failures till I noticed cbuild was pulling in the wrong
branch of meta-linaro (now fixed)
* added support for checking the oe-core build prerequisites
* the images are now automatically bootet using qemu
* sizes of the images and package sizes are now recorded
* update to Linaro GCC 4.6 2012.05 (denzil) and Linaro GCC 4.7 2012.05
(master)
* debugged build failure when using Linaro GCC 4.6 in a hard float
configuration
* turns out that OE expects the GCC to respect the
ARCH_FLAGS_FOR_TARGET env variable
to build libgcc and friends properly for the given target
(another missing patch to build the GCC the OE-Core way)
* fix tested and checked in (denzil)
* created/updated wiki pages:

Hi,
GDB for Android:
* Fixed the PC offset in jmp_buf but the patch still wasn't working.
It turns out that GDB wasn't loading the libc6.so symbols even though
I set both sysroot *and* solib-search-path. Copied libc6.so to GDB's
cwd and the patch worked (will investigate this next week).
Submitted upstream, currently under review.

Hi,
GDB for Android:
* Worked on patch which uses the correct offset for finding the PC value
inside the jmp_buf on Android binaries. Things weren't working though,
and in the end it turns out that the value used in AOSP's patch is
wrong.

Hi Zhenqiang. I've had a look at the difference between testsuite
results on our current softfp Natty builders and the new hard float
Precise builders. The diff and notes is at:
http://people.linaro.org/~michaelh/incoming/hard-float-builder-diff.txt
There's a lot of commonality:
/usr/bin/ld: cannot find {S,g}crt1.o: builder fault. I've fixed this.
sorry, unimplemented: Thumb-1 hard-float VFP ABI errors: tests where
they set the architecture to ARMv5T and use our default Thumb mode.
This causes the compiler to fail as it doesn't support Thumb-1 with
hard float.
arm_iwmmxt_ok5222.c:1:0: sorry, unimplemented: iWMMXt and hardware
floating point

Could you look into the unsupported ones please? I'll fix the crt1
problems and respin the build.

The Precise based hard float auto builders are now online. Every
merge request and commit to gcc-linaro will now be built build both on
a Natty softfp system and a Precise hard float. Let's run this in
parallel for a while before updating the validation lab.
I've also updated the x86 cloud builders from Natty to Precise. A
quick test showed no regressions but I want to run them in parallel
for a bit to be sure.
-- Michael
Progress
* Proposed backport for vfp addressing modes patch.
* Investigated the build issue with EEMBC and have a candidate patch
for upstream trunk. (PR53334)
* Investigated auto-inc-dec sched changes.
* Some upstream patch review.
Plans
* Work on auto-inc-dec sched changes.
* Finish PR53334 patch upstream.
* Work through some of the speed tickets and upstream bugzilla perf
tickets in preparation for connect.
Remerged the GCC 4.7 branch from upstream. I had previously
misunderstood how to resolve a conflict where Uli had committed a
different version of the same patch upstream.
Spun the GCC 4.6 and 4.7 release tarballs and passed them to Michael for
testing.
Continued work on improving code generation for 64-bit and/or/not/xor. I
now have this working to the point where it would be ready to post
upstream .... except that it depends on my other patches that are not
yet committed (or even reviewed) upstream.
Rebased and modified my core-shifts patch following Ramana's code
review. Then regression tested it - no regressions - and committed the
patch upstream. I've also updated the launchpad branch and resubmitted
the merge request with the finalized upstream patch.
Rebased the neon-shifts patch. I'll repost this upstream as soon as I'm
happy it still works correctly.
Worked on a brain-dump of all I have been working on recently. This will
hopefully help others take over my tasks after the contract expires. I
still need to put together all the test-cases and examples that Ramana
requested.
