= Progress ==
* Created Cards for the infrastructure Team TODO list.
* Finished Cbuildv2 support for building GDB binary tarballs.
* Got Arch linux up on Odroid XU board again, seems stable, did a
build and test run.
* Experimented with lava-tool.
* Tried to get GCC trunk building native on aarch64 for libsanitizer
patch testing.
* Upgraded gmp to 5.1.3 in infrastructure/ to work around a configure
bug triggered by crouton native builds on a chromebook.
* Setup chromebook slaves in new toolchain build farm.
* Started adding support to Cbuildv2 to handle git URLs with a user
name, ie.. git(a)staging.git.linaro.org to work around git repo
problem.
== Plan ==
* Finish support for user names in URLs.
* Continue on remote testing support.
* Keep trying gcc trunk on aarch64 native.
* Fix git repo.
== Issues ==
* GCC git repo hasn't been auto updating the svn branch of
linaro-4.8-branch. It used to work... updating manually is now
broken as well.
* Somehow qemu snapshots tarballs are overwriting the toolchain
directories on snapshots.linaro.org.
* I don't think lava-tool is going to be useable for toolchain
testing, as it only queues up an executable test case to be run
later, whereas GCC expects the test to get run right away.
One day off
== Progress ==
* Prepared 4.7 and 4.8 2013.11 releases. Some delay because of board
crashes and disk full issues.
* Aarch64: committed 'frame grows downward' patch. This removes a
dependency for libsanitizer and libssp.
* libsanitizer on Aarch64: blocked by GCC trunk not bootstrapping
currently on Aarch64 HW (reported by Rob)
* Looked at cross-build failures of trunk after new
-fisolate-erroneous-paths. Ramana pointed me to Marcus' glibc patch,
and I could switch my builds from eglibc to glibc.
* cross-validations: updated list of configurations built&tested after
discussion with Richard during Connect.
== Next ==
* Announce 4.7 and 4.8 2013.11 releases
* Continue investigating 'extended neg' fix (aka tar regression)
* Look for patches to fix AArch64 bootstrap, so that we can test libsanitizer
One day off.
== Issues ==
* Various cbuild issues:
- disk full, boards down and benchmarks launched on different boards
== Progress ==
* LRA on AArch32:
- Proposed a ARM backend fix for the Fortran issue
http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01997.html
- Performance analysis ongoing
* Merge reviews and backports.
== Next ==
* Continue on LRA
== Progress ==
* Wrote ARM and Thumb stub handlers for simd, vfp and coprocessor
instruction recording.
* Read documentation on VFP and Neon register set to figure out a register
recording method.
* Follow up on upstream patches.
* Investigating a un-handled instruction test suite failure in arm process
record.
* 9th/10th Muharram Public holiday on Thursday and Friday.
== Plan ==
* Fix failures in arm process record due to un-handled instruction.
* Get started on writing handlers for coproc, vfp and simd instructions.
== Issues ==
* None.
== Progress ==
* One day (Nov. 15) off.
* Misc update for Linaro crosstool-ng
- Use newlib-linaro-2.0.0-2013.11-1.
- Update fortran support related scripts and configs according to
Matt's comments.
* Propose to support S2_<op1>_<Cn>_<Cm>_<op2> system register in AARCH64 GAS.
- Yufeng followed-up it and added full TRACE registers support.
* Investigate heuristic to tune ifcombine (TCWG-313)
- Got some new fails in regression tests since some optimizations
can not get the expected result.
- Collect Spec2k INT result. Overall there is no changes. But there
are -2 - 1% changes for several cases.
- PGO tests are ongoing.
== Plans ==
* Continue on CCMP.
* Continue on ifcombine tuning.
== Progress ==
* Preparing presentation on auto-vec for LLVM
- For Cambridge LLVM Day next Monday
- If accepted, also for FOSDEM 14
* Tracing strided access changes needed in auto-vec (PR17677)
- Reading the paper, preparing a reference implementation
- Discussing details and preparing the LLVM code to introduce it
- After a few attempts, it's clear that the code is not yet ready to cope
with the changes
- I'll have to work on the surrounding code to re-factor it for more
robust integration
- As well as triming some other edges (like pragmas) to help implement it
* Planning Android builds
- Trying to get a reference platform (most likely the new Arndale)
- LLVMLinux folks will help streamlining a kernel package for it
* Connect reservations, booking flight, etc.
- All done!
== Plan ==
* Monday at Cambridge LLVM Day at CUCL
* 3.4 Release testing
* Looking at vectorization pragmas and general structure of the memory
dependency checks
== Progress ==
* Fix ld testsuite on mainlne
* More malloc debugging and refactoring
* glibc patch review
* Investigate gdb hardware breakpoint issues
== Issues ==
* Didn't get much done on Friday due to sick baby
== Plan ==
* malloc
* Follow up glibc docs patches
* Further investigate gdb hardware breakpoint issue

Toolchain Working Group, Linaro
Short week: 2 days off after Connect.
== Progress ==
* LP 1243656: reverted commit which causes a regression in GNU tar's tests.
* Committed Kugan and Zhenqiang's backports to our branch
* Status on backports: ILP32 support missing from binutils is blocking
quite a few GCC backports (because of dependencies between commits)
* Some problems building trunk since Nov 5th (failures in eglibc)
== Next ==
* Make 2013.11 releases
* Continue working on GNU tar problem: find a proper fix.
* Commit 'aarch64 frame grows downward' patch if Richard approves it.
* Check status of aarch64 lib sanitizer branch if Rob manages to have
it build & execute tests
* Check Neon intrinsics testsuite status with Rob
== Progress ==
* Monday off for recovery from Connect.
* Created git_revisions branch for refactoring
* Added verified and correct --help and --usage text.
* Error check for spurios '=' after --<switch>
* Add toplevel test.sh for testing cbuild2.sh commands
* Fix get_URL and checkout to support git revisions.
* Improve dryrun to prevent grepping missing files.
* Added glibc support to cbuild2.
* Cleaned up merged cbuildv2 remote development branches
* Started cbuild2 bisect.
== Plan ==
* Merge glibc support upstream
== Issues ==
* None
