* Once Jenkins has a node_selector for the new Beagle Board Blacks,
get those working for native builds. (TCWG-379)

* Continue on LRA and lib GMP.
- 2014.01 releases: (2/10)
* 4.7 ready, 4.8 needed a short daily to include our multilib patch
to support our binary releases.
* retried cbuildv2 and sent feedback. Should be mostly OK by now.
- cross-validations: (2/10)
* followup-up, bugzilla
* thinking about short term Neon intrinsics testsuite use without dejagnu
- libsanitizer (2/10)
* resumed work for aarch64
- misc (2/10): conf-call and meetings
- internal support (2/10)
* issue:
boards used for benchmarking have been off for several weeks. Pending
jobs disappeared from the list, but I got no log.
== Progress ==
* Implement fork over HW breaks support for arm native targets.
[TCWG-177] [6/10]
* ARM Process Record:
- All patches accepted and upstream.
- Spent time making changes to VFP, SIMD etc patch. [2/10]
- Configuration and Git ssh setup for gdb commit rights . [1/10]
* Submitted a new fix and worked with community for the fix. [1/10]
== Plan ==
* Continue to work on fork over HW breaks support for arm native
targets. [TCWG-177]
* Patch updates and submission to all in progress upstream submissions.
* Travel to Islamabad for Macau visa application.
== Progress ==
* Libc probes support for Aarch64.
Testing the patch for "libc" probes support to "__longjump".
Native compiling in openemebedded.
Obtained a Linaro open embedded image with system tap enabled.
Getting Assembler Error during "malloc" module linking in "glibc"
configured with --enable-systemtap.
In libc_mallopt invalid "asm", invalid expression as operand for
LIBC_PROBE call.
Cross compiling.
Tried copying header files from system tap source to SYSROOT for cross
compiling glibc. The cross compiled GCC does not recognize the header
files.
* Investigate "PGO" for Aarch64.
Started bootstap testing GCC with PGO for GCC.
Stage 1 completed. stage profile in progress.
== Plan ==
- Run EMBCC benchmark with -PGO enabled.
- Work on "glibc" probe.
== Issues ==
Waiting for feedback on "libssp" machine descriptions changes.
Misc
------
14-Jan-2014 Local holiday.
== Issues ==
* None.
== Progress ==
* Test Linaro cbuildv2.
- Write a reference script to support windows installer in cbuildv2.
- Do some basic validation work against the binaries built from cbuildv2.
* Reproduce and work out a patch for "ICE when building
linux-linaro-tracking" (lp:1268893, PR59837) .
* Test to merge Linaro local armv4t multilib patch to Linaro 4.8.
* Investigate CCMP chance by taking a Bool_ var as var != 0.
== Plans ==
* cbuildv2 validation
* Tuning ccmp performance
== Planed leaves ==
* Jan. 31 - Feb. 9.
== This week ==
- Completed merge of crypto backports 206128, 206130, 206131, 206132 and
206149 from trunk to Linaro 4.8 branch
- Out sick Friday
== Next week ==
- Build and test crypto backports
- Begin merging aarch64 crypto backport to Linaro 4.8 branch
== Future ==
== Progress ==
* Cbuildv2 fix for *_release() functions which were changing out of
the build directory but then not changing back to the builddir, which
caused problems with paths relative to the builddir. (1/10)
* TCWG-340 Enable Glibc remote testsuite integration - (7/10)
- Working with upstream community on scoping and designing remote
testsuite integration.
- Setting up arm chroot environment on chromebook with documentation
on how to make this reproduceable.
* TCWG-352 AArch64 clone is missing some CFI markup - (2/10)
- Setup aarch64 environment for testing and built static clone tests
to test the patch.
== Plan ==
* Start implementing (code) for glibc remote testsuite integration.
== Issues ==
None
== Progress ==
* Buildbots
- Odroid U2 died after a few days on USB stick, too. (I guess we're stuck
with Chromebooks)
- Upgrading chromebooks (to Saucy) due to a new GCC/libstdc++ 4.7+
restriction
- Shuffling chromebooks, we now have three buildbots:
- llvm-chrome-01: quick-build+check
- llvm-chrome-02: self-host+check
- llvm-chrome-03: test-suite
* MCJIT Remote
- Re-factored the communication protocol of MCJIT for remote processes
- Still seeing one random failure on ARM, investigating
* Compiler-rt
- Investigating how to get it compiling all libraries and sanitizers on ARM
* Background
- Patch reviews, especially IAS and EH
* Time
- CARD-862 8/10
- Others 2/10
== Plan ==
* Continue MCJIT and Compiler-RT investigations
* Continue reviewing IAS and EH patches
* Try to run the EH tests on the test-suite with the current changes
