== Progress ==
* 3.3 Release
- Bootstrapping, testing, fixing bugs, etc.
- RC1 released on Tuesday
http://people.linaro.org/~rengolin/llvm/
- Fix for C11 atomics on Linux
http://llvm.org/bugs/show_bug.cgi?id=15429
- Fix for zero extend vector bug in test-suite
http://llvm.org/bugs/show_bug.cgi?id=15970
* Test-Suite
- ClamAV fails on Calxeda, same as PPC64 (bad test)
* Self-Host Buildbot
- Re-purposing the Panda back to buildbot service
- Buildbot passing green, setting it up on Build Master
== Issues ==
Calxeda gets turned off quite regularly, which messes up any long term
commitment you might have for them.
== Plan ==
* Install Ubuntu on Chromebook, run benchmarks with 3.3 RC1
* Try to revive LLVM CBuild job if it's any different than our current
buildbot
* Try to setup benchmark jobs for LLVM, either buildbots, CBuild, or
whatever
* Stay alert for RC2 and re-run release process on them
== Progress ==
* Finished porting ld-ifunc tests to AArch64.
* Requested a relocation number for R_AARCH64_IRELATIVE.
* Tested AArch64 ifunc code natively to run generic ifunc tests.
* Investigated gdb bug #1175525 and submitted workaround patch to gdb-patches.
* Started DeveloperTools and LibraryPerformance wiki pages.
* Submitted initial version of AArch64 binutils patch with temporary
reloc number.
== Issues ==
* None.
== Plan ==
* Complete process of getting R_AARCH64_IRELATIVE allocated.
* Feedback on binutils AArch64 ifunc patch.
* Feedback on slightly hacky gdb patch.
* bionic memcpy.

== Progress ==
* Disable-peeling: analyzed regression on one bench.
* Libsanitizer/aarch64:
- porting will require more effort than aarch32.
- some syscalls are not supported by aarch64
- libsanitizer expects frame to grow downwards (true on aarch32,
false on aarch64)
* PGO/LTO bug reported by Doko: updating board environment to reproduce it
* Internal support
== Next ==
* Disable-peeling: see how to disable too aggressive vectorization
* Revert-coalesce-vars: discuss how to handle it with the team
* Neon intrinsics: continue improving crc with vuzp
* Neon intrinsics tests: handle feedback if any
* PGO/LTO bug: reproduce it
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

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.
