Progress:
* QEMU maintenance:
** versatile-pb PCI: sent kernel patchset, so this is off
my queue now unless there are problems in review
** interviewing candidates for Linaro QEMU position
** sent pullreq for various accumulated QEMU patches now 1.7
development has opened up
** booked travel, hotels for Connect USA, KVM Forum

Hi,
I was trying to build a gcc-linaro that targets AArch64 (mostly
following guides such as http://jk.ozlabs.org/docs/arm64-toolchain/) and
failing, to be short and simple. Unfortunately I don't have the errors
I was encountering to hand, so instead I'll ask: Is the build process
for building aarch64-linux-gnu-gcc and friends documented anywhere?
Cheers,
mwh
== Progress ==
* Spent a couple of days studying existing patches and code changes made
for reverse debug support.
* Evaluated record n replay and reverse debug support by testing these
features in various configuration with few forced code changes.
* Evaluated catch syscall patch by running it on chrome book.
* Finally submitted UK visa application. Spent a couple of days preparing
documents getting them attested and took the trip to UK visa application
center for application submission.
* Independence Day Public Holiday on 14th August.
== Plan ==
* Continue work on Reverse debug on arm major task next week is to study
arm documentation and identify changes required for thumb32 support in
process record and replay feature.
* Review and update TCWG Libraries and Dev tools wiki pages.
== Progress ==
* Libssp support for AArch64 TCWG 23:
Understood the TCB datastructure. Sent a mail to the internal team on the
changes needed and where to put stack gaurd slot in TCB.
Got some comments from Matt. Worked on the changes in eglibc.
Tested a simple stack smashing program in V8 model by moving
the patched run time linker and glibc. Sent the RFC internally for review.
* 4 day week 15-August India naional holiday.
== Plan ==
* Post RFC patch for Libssp support for AArch64 in GCC and glibc TCWG-23
* Continue testing the patch for Libssp support for AArch64 in GCC and
glibc TCWG-23
* Backport and test revision 201406 to linaro branch.
== Issues ==
* LTO/PGO work stopped now since libssp support priority is more.
* Waiting for Marcus feedback for Matt comments on gprof patches TCWG-20.

== Progress ==
* 2013.08 4.8 release:
- completed achievable backports (postponed some with problems to
next release)
- created & uploaded release. Will be announced next week along with 4.7
- Matthias a reported a problem in c++/java
* Aarch64 frame layout: submitted sample code for internal discussion.
* Wiki cleanup: started
* trunk validation:
- continued to work on internal validation of trunk using our
compute farm (build+cross validation) to help catch regressions early.
- validating every commit seems too heavy currently
== Plan ==
next week off
