== Progress ==
Very short week (monday and wednesday off).
* AARCH64 testing
Got boot strap failure with GCC 4.9 trunk on open embedded image with
glibc changes. Retired with latest openembedded image on V8 model
Noted down the steps to reproduce boot strap failure in the model for
broadcasting.
* libssp support for Aarch64
Read documentation to understand and evaluate the work.
== Plan ==
* Continue bootstrap testing and push patches to GCC
* Implement Libssp GCC back end hooks.
* Linaro connect travel prep, book tickets hotel and apply visa.
== Progress ==
* VRP based zero/sign extension
- Tested and posted the latest patch
* Better end of loop counter optimisation
- Tree level optimization are optimized in mainline
- Christophe noted a slight change in asm generated from earlier
version
- tracked down the patch causing this and communicated this.
* Generate a single call to divmod
- Looked at expand_divmod to understand how __aeabi_idiv and
__aeabi_idivmod are generated.
== Plan ==
* Better end of loop counter optimisation
- Change the pattern to remove this additional instruction if
necessary.
* Generate a single call to divmod
- Come up with a solution
== Issues ==
* None
== Progress ==
* Shrink wrapping improvement (TCWG-133)
- Call copyprop to optimized the parameter register move instructions.
- Test is ongoing.
* Update aarch64-none-elf toolchain newlib version to 2.0~20130530 (lp:1185711).
== Plan ==
* Collect performance data for TCWG-133.
* Continue on conditional compare.
Best Regards!

== Progress ==
* Monday holiday here too, so went mountain climbing
* Finally fixed Lava token for cbuild
* Dug into EC2 issues, still confused
* Cloned infrastructure files from gcc.gnu.org, which turned out to be
out of date, so updated them to the current releases. That then
required fixing a few minor configure bugs in libppl. Files in
~/cbuild/var/snapshots/infrastructure. Infrastructure libs are
statically linked so they're consistent across platforms.
* Worked on cbuildv2, it now downloads a tarball or does a
bzr|git|svn checkout, configures, compiles, and installs them in
a sysroot as other packages depend on them. Also added a function
to download, build, and install all the toolchain infrastructure
libraries in a sysroot for binutils & GCC to use at build time
https://git.linaro.org/gitweb?p=people/rsavoye/cbuild2;a=summary
* Automated import of all historical test results till running.
Currently
the DB has 137,687,996 test results, 1909 separate test runs of GCC,
and covering 544 versions.
== Plan ==
* Add remote SSH support to DejaGnu for remote testing on
Chromebook. (carried over from this week)
* Figure out the EC2 mess and document it better
* Clone gcc_release.sh script but enhance so a similar process can be
applied to releasing Eglibc, Newlib, and the Binutils.
* Start gearing up for the releases
* Finish cross build and testing support in Cbuildv2, which would
basically eliminate the need for crosstool-ng.
