== Progress ==
* GCC trunk/4.9 cross-validation (1/10)
  - submitted a couple of patches to clean testsuite cases

* Neon intrinsic tests (1/10)
  - submitted patch to avoid running the tests on ARM targets w/o Neon
  - started adding new tests
  - created 2 PR about intrinsic tests failing on AArch64_be
(1 assigned to Venkat, 1 to me)

* AArch64 sanitizer (1/10)
  - submitted a patch upstream to allow supporting both older and newer kernels
No feedback so far.

* GCC 4.8 and 4.9 releases (3/10)
  - preparing both releases including ARM's latest fixes for the A53 erratum
  - had to respin mid-week after new fix was committed
  - LINK_SPEC patch not committed yet in 4.8, and committed in 4.9
after I made the branch merge.
  - now checking results with references. Several FAIL appear. TBC.

* cbuild2 schroot and master branches comparison (1/10)
  - re-ran schroot branch after cleaning spurious "-static" flag left
in dejagnu configuration
  - better results, faster

* Misc (3/10)
  - calls, meetings

== Next ==
* GCC 4.8 and 4.9 releases: hopefully, after branch merge review
* AArch64 sanitizer
* Neon intrinsics tests update
* cbuild2:
  - analyze previous results
  - look at backport-test and tcwgweb scripts + logs

== Progress ==
* Zero/sign extension elimination with widening types (TCWG-546 - 10/10)
 - Fixed regression failures
 - Fixed bootstrapping issues for ARM and AArch64
 - Re-factored and added some comments
 - x86-64 Bootstrapped and regression tested for all languages with
forced promotion. There is 6 differences in scanning for certain
instructions. All the execution tests are passing.  Needs further
investigation.

== Plan ==
* Continue with Zero/sign extension pass.
 - Benchmarking
 - Get patch ready for upstream discussion

* Improve block memory operations by GCC (TCWG-142)
  - Start work on this
