Progress:
* VIRT-49, VIRT-50 [cp15 migration, reset]
** last bits of patch cleanup complete; realised I could test
KVM migration without any timer or vgic patches; did so and
sent first version of patches out to qemu-devel
* VIRT-55:
** started to draft basic notes on what we want to test:
https://wiki.linaro.org/PeterMaydell/MigrationTesting
* misc
** reviewed Huawei's aarch64 tcg target patches; there are some
issues they need to fix but overall looking good
** fixed a last-minute bug in the versatilepb PCI controller
model (some changes we made earlier in the release cycle
wouldn't work with newer Linux kernels)
Plans:
* deal with any code review feedback on patchset
* set up a raring/aarch64 cross build environment (got partway
through this, waiting for wookey to update some packages)
* more in-depth review/test of John Rigby's mach-virt, aarch64 patchsets
* VIRT-55: write up how to test migration (and talk to Andre
about what he's doing testing-wise)

Hi, All
The attachment file is analysed by the streamline tool.
How to do you think about the vsub.f32 hot spot there?
Is there any way we can improve that?

== Progress ==
* Filled up the googledoc comparison sheets of gdb 7.6 test suite run in
different configuration on chromebook and x86.
* Filled up the googledoc comparison sheets of gdb 7.5.1 test suite run in
different configuration on chromebook and x86.
* Compared GDB 7.6 and 7.5.1 results which show good improvements in gdb
7.6.
== Plan ==
* Repair my laptop's ubuntu installation which crashed for some reason.
* Submit patch to fix dwarf test suite in gdb 7.6
* Investigate gdb 7.6 gdb.base failures on arm and try to figure out causes
+ possible solution.
* Try to figure out a way automate a comparison of two test suite results
and upload them to googledocs.
Hi,
I downloaded 13.04 version and tried to compile linaro-image-sdk and
linaro-image-lamp. Both these builds fail with the following error.
However, I could compile core-image-minimum. Can somebody help me with this
issue? Is there any quick workaround. Mostly, I do not need ltp package.
Thanks,
Aparna

== Progress ==
* AARCH64 - gprof support.
Submitted GCC patches to generate profile call.
Also applied the review comments from Marcus and tested patches for
aarch64-none-elf.
http://gcc.gnu.org/ml/gcc-patches/2013-05/msg00597.html
* Setup a Ubuntu machine at Office.
Ran GCC testsuite with on openembeded/V8 model
ref: http://people.linaro.org/~hrw/oe/vekumar/.
This image has updated gcc and glibc and enables gprof.
During bootstrap GCC build failed due to space getting over.
Need to create a larger image.
* Looking at how to handle builtin_return_address when
-fomit-frame-pointer is enabled.
GCC saves frame pointer for the function alone where
builtin_return_address is used.
Callers of the function may not have set up the frame yet.
== Plan ==
* Continue gprof "-c" option support in binutils
* Continue handling builtin_return_address when -fomit-frame-pointer
is enabled.
* Continue gcc bootstrap and regression suite after creating a larger image.
== Progress ==
* 3.3 Release
- Running tests on Pandas and Calxeda, Ubuntu 12.04 and 12.10
- Chromebook arriving next week
- Calxedas died a couple of times this week for no reason (somebody else
turned it off?)
- Many bootstrap failures on 12.04: check-all, test-suite, etc on all
phases
- Fixing a bug that allows to bootstrap on Ubuntu 12.10
* EuroLLVM 2013
- Published the questionnaire results, wrote a post on the blog
- http://blog.llvm.org/2013/05/eurollvm-2013-paris-france.html
* Extra
- Studying C++11 atomics
== Issues ==
There's no way to tell when someone will turn the Calxeda server off, so
relying on its results or usability is folly. Not to mention that the
designers should have had a bit more care on the interface to power up and
configure nodes.
== Plan ==
* Spend the weekend testing on the Pandaboard with Ubuntu 12.10 and see if
the fix is good, commit
* Install Ubuntu on Chromebook arriving on Monday, run release tests on them
* Hope that Ubuntu 12.10 will be less hemorragic than 12.04 for the LLVM
release...
Short week (3 days)
== Progress ==
* Disable-peeling: got results vs reference, shared with team.
* Revert-coalesce vars: got results vs reference, showing regressions.
* Libsanitizer: committed upstream.
* Neon intrinsics: shared initial proposal of dejagnu-ization of my
existing tests.
* Branch reviews
* Internal support
== Next ==
* Disable-peeling: investigate regression on eon
* Revert-coalesce: discuss how to handle it with team
* Libsanitizer: enable on aarch64
* Neon intrinsics: continue improving crc with vuzp
* Neon intrinsics tests: continue dejagnu-ization
== Progress ==
* Four day week and traditional bank holiday cold slowed progress.
* Tested glibc memcpy patch on big endian and got it committed.
* Submitted some generic IFUNC patches for binutils upstream.
* Further work on AArch64 IFUNC support in binutils.
== Issues ==
* cbuild seems to not be doing much building at the moment.
== Plan ==
* Complete AArch64 IFUNC support and submit a patch.
* Look further at gdb bug if I get time.
