* GDB Record and Replay (TCWG-197)
Studied ARM Thumb32 instruction encoding for thumb32 encoding
Studied existing arm/thumb code for instruction decoding and recording
Setup remote debug environment to debug arm native gdb record/replay code.

(+linaro-toolchain, which I dropped at the start)
I had a hack and set up a chroot on my Tegra 3 OUYA to run distcc.
With the Wandboard driving and a 'ninja make -j12', LLVM 3.3 built in
75 minutes (meh). You really need the 2 GiB of RAM - the 650 MiB left
on the OUYA plus the occasional four 250 MiB g++ hurts.

* Nice holidays in Brittany.
- Wine, cheese, more wine, some beaches...
* ODroid buildbot still running...
- After a long and hot week with all windows close (room temp > 25C), the
bot has held stable no hotter than 63C and is running self-hosting
(partial+full build) without a single hiccup.
- I'd be very happy with them as buildbots (rather than Chromebooks)
- I'd also be very happy to test the ODroid X2 (octo-A15/A7)

around)

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.
