== Progress ==
* AARCH64 - gprof support.
Completed gprof -c support for aarch64.
Got reviewed internally by Matt and Will.
Patch yet to be posted. Waiting for some feedback on copyright message.
*Testing GCC bootstrap and regression suite.
Created a large image with help of Bero.
Bootstrap fails with GCC trunk libgcc_eh.a (unwind-dw2-fde-dip.o)
hidden symbol __register_frame_info is referenced bu DSO
ld final link Bad value.
Drilling down
== Plan ==
* Post patches in gcc and binutils for gprof work
* Continue handling builtin_return_address when -fomit-frame-pointer
is enabled.
* Continue gcc bootstrap and regression test.
== Issues ==
* Cbuild down most of the week.
== Progress ==
* 4.6 and 4.7 releases
- Released after a painful week !
* LRA on ARM and AArch64:
- Enabled on AArch64, but it leads to an ICE too.
- Applied Brice's ARM patches didn't solved the issue.
- Looked at the documentation/comments to understand the process.
- Debug ongoing.
== Plan ==
* Continue on LRA
== Issues ==
* None
== Progress ==
* Continue on conditional compare.
- Mix fixes for bootstrap.
* Update shrink-wrap patches according to comments and retest them on
Pandaboard and Chromebook.
* Prebuild 2013.05 Linaro toolchain locally.
- gdb related local patches need rework.
== Plan ==
* Continue on conditional compare to bootstrap.
* Linaro toolchain 2013.05 binary release.
Best Regards!

The Linaro Toolchain Working Group is pleased to announce the release
of Linaro GDB 7.6.
Linaro GDB 7.6 2013.05 is the first release in the 7.6 series.
***NOTE*** Linaro GDB 7.6 2013.05 is identical to the FSF GDB 7.6 release,
except for the change in version number and Linaro branding, since all
Linaro GDB features were already accepted upstream and are included in
the FSF release as-is. Future releases in the Linaro GDB 7.6 series may
include additional ARM-focused bug fixes and enhancements.
The source tarball is available at:
https://launchpad.net/gdb-linaro/+milestone/7.6-2013.05

== 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.

Toolchain Working Group, Linaro
== 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)
