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
== Progress ==
* Monday and Tuesday off for Jetlag recovery.
* Arm process record:
- Updated Patches for all fixes and features.
- Performed testing in arm native and remote configuration.
- Performed regression testing on arm and x86.
- Submitted all new patches after updates.
* Started gdb.reverse test suite failure investigation and open new Jira
issues accordingly.
* Started work co-processor instructions decoding for arm process record.
== Plan ==
* Continue work on co-processor instruction decoding for arm process record.
* Respond to upstream suggestions on patches sent previously.
== Issues ==
* Binaries build FAIL in cbuild, but OK in local build.
== Progress ==
* Misc update for Linaro crosstool-ng
- Update newlib to 2013.11.
- Modify scripts to meet the check of A-profile multilib support.
- Add fortran/libfortran support for bare metal build.
- Fix multi-lib conflict issue in local patch
- A refer A-profile bare metal build is shared at
http://cbuild.validation.linaro.org/snapshots/gcc-linaro-arm-none-eabi-4.8-…
* Update conditional compare patch according to comments.
* Investigate heuristic to tune ifcombine (TCWG-313).
== Plan ==
