== Progress ==
* Debugging and analysis of various gdb test suite failures [TCWG-34] [5/10]
Updated googledoc sheet with action items and comments on different failures.
Investigated remote core file generation issues.
Prepared a patch to turn off corefile dependent tests in remote configs.
* Debugged gdb.reverse testsuite failures [TCWG-197] [4/10]
Found a memory corruption issue where execution log is being corrupted
in memory.
* Time off for dentist appointment and office relocation stuff [1/10]
== Plan ==
* Figure out a reason and fix for process record memory corruption problem.
* Further analysis of test suite failures in arm-native Vs x86-native
and arm-remote Vs
x86-remote test results.
* Send patch to disable corefile tests in remote mode. Ping process
record and other previous patches.
== Progress ==
- Libssp GCC (4/10)
- Rebased GCC source and added patch for stack protect and test
based on global stack guard. Discussing with Marcus on
generic stack protect set and test versus machine descriptions.
Discussed with ARM and Glibc Maintainers, Dropped my patches
for TLS based stack guard.
- Cbuildv2 experiments (3/10)
- Built cross compiler with Cbuilv2.
- Discussing with Ryan on building tool chain without
cbuild.validation.linaro.org dependency
- PGO support for aarch64 (1/10)
Read a paper on PGO optimization in GCC
- Cross build some benchmarks(2/10). There were omp.h file missing
errors when Linaro tool chain was used. The issue is the tool chain is
not built with libgomp library. Rebuilt the tool chain after checkign
configuration changes with Zhenqiang Chen .
== Plan ==
- Inverstigate Pointer Guard support in Aarch64 glibc
- Continue tesing Cbuildv2
- Continue PGO investigations
== Issues ==
* None.
== Progress ==
* Enable libomp for aarch64*-linux-gnu builds in Linaro crosstool-ng.
* Backporting r200103 and r205509 to Linaro 4.8.
* Try to enable lra and test Spec2k with -fno-move-loop-invariants and
-fira-loop-pressure. But still no overall performance improvement.
(2/10)
* Try conditional compare related changes (CARD 313: 3/10)
- Set LOGICAL_NON_SHORT_CIRCUIT to false in fold-const.c.
- Do ifcombine twice.
- Logs show lots of new FAILs in vrp related cases and no
performance improvement in Spec2k INT.
* Identified the root causes of "uninit warning testsuite failures"
(CARD 304: 3/10)
- Some values are from PHI, which is not handled when checking subset.
- Function is_included_in is conservative. Here is its comments:
/* ... It returns false if ONE_PRED's domain is
not a subset of any of the sub-domains of PREDS (
corresponding to each individual chains in it), even
though it may be still be a subset of whole domain
of PREDS which is the union (ORed) of all its subdomains.
In other words, the result is conservative. */
== Plans ==
* 2013.12 toolchain binaries release.
* Continue on CARD 313 and 304.
== Progress == (4/10)
* TCWG-372 fix Cbuildv2 parsing to handle the new binutils-gdb repository (4/10)
- Completed Card with following commits.
commit e6e39f5d1f7963332b3d7dd2e4400de91847219c
Author: Ryan S. Arnold <ryan.arnold(a)linaro.org>
Date: Tue Dec 10 16:08:17 2013 -0600
Correct get_toolname to work with unified repo: binutils-gdb.git
Secondary fixes required:
- Set config/binutils.conf and config/gdb.conf to use unified repo
binutils-gdb.git.
- Re-enable binutils-gdb.git in config/sources.conf.
- get_toolname now calls get_git_tool and determines the actual toolname
for binutils and gdb from the branch name if the repository is unified.
- Made all other usages of get_git_tool use get_toolname instead.
- checkout() now uses ${repo} as returned from get_git_repo as the git
repository instead of ${tool}.git. This allows a unified repository to
only be checked out once.
- The git parser now determines whether an http:// in a url means a git
service or an svn service.
- The git parser now returns branch names for launchpad urls with branches
in the url.
- The git parser now returns the tool name properly for an svn service.
- The git parser testsuite now has testcases for all new additions.
Also
- Added --snapshots functionality to allow specifying an existing snapshots
directory.
- Add testcases to test.sh to test --snapshots functionality.
- Changes test.sh --snapshots directive to --md5sums to avoid confusion
with cbuild2.sh --snapshots.
* TCWG-323 Interface hardening (5/10)
- Card in progress with following commits:

Require change due to commit 3b5c576630a8ac08cd3b9ab9eab781308549a858
which requires a host.conf file for finding the cbuild topdir.

made suggestions and edits.
== Plan ==
* Move onto working primarily on glibc Jira cards.

unplanned days and therefore toolchain sources were unavailable during
that time. I made do by adding some features into cbuildv2 to use
alternative snapshots directories.

== Progress ==
- cross-validation: (1/10). Follow-up, minor maintenance and
discussions on a few regressions. Now able to share top-level
reports.
- backports (1/10):
* multilib_defaults for 4.7
* committed all approved backport
* helped Michael solve some conflicts
- disable peeling: (3/10)
* confirmed it is now done by default on trunk, as part
-fvect-cost-model=XXX.
* Looked at benchmarks, comparing
-fvect-cost-model=cheap (default) and
-fvect-cost-model=unlimited.
- benchmarks on trunk (1/10): observed some variations from one month to
another on a few cases (checked June-November). This confirms
the need to run benchmarks regularly on trunk, in addition to
release branches.
- cbuild2 (3/10): continued working on source release. Submitted a few
small patches for review+integration.
- misc (1/10): various conf-calls and meetings.
== Next ==
- Make 2013.12 releases
- cbuild2: continue testing, try to make 4.7 source release
- libsanitizer on AArch64: resume work
