== 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.
Misc
------
23-August availing leave.
== Progress ==
* spec2k comparison between ARM and x86
- Trying to reproduce some of the earlier optimization studies
- Set up Acovea Trying milepost gcc
* VRP based zero/sign extension elimination
- Posted the modified patch
== Plan ==
* Continue with spec2k comparison between ARM and x86
* Wiki Cleanup
== Progress ==
* Made it back from the Tetons after a rainy climbing trip
* Helped Vish with #357
* Cbuildv2 improvements for cross builds and binary releases
* Wrote script to for better Jenkins support
* Added more user parameters to Jenkins config page for building
toolchains.
== Plans ==
* More work on Cbuildv2 for building binary releases
* Write more Cbuildv2 docs
* More help on #357
* Start going through Wiki pages
* Investigate lava-tool so Cbuildv2 can use Jenkins slaves remotely
== Progress ==
* Short week (3 days off to move house)
* Submitted outstanding glibc patches after 2.18 release
* Wrote some glibc allocator tests which have exposed some minor issues
== Issues ==
* None
== Plan ==
* Complete glibc allocator tests and submit them
* Get malloc implementation functionally complete

Toolchain Working Group, Linaro
== 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
== Progress ==
* Connect / LLVM Meeting
- Checking times, booking tickets, etc
* Divmod
- Some more divmod work, SelectionDAG changed enough to break my merge
- Since it's only 64-bit support, we'll postpone implementation for a
later date
- Internal discussions with ARM, trying to approach it in a different way
* Buildbots
- Investigating MCJIT test failure in buildbot
- Some other random breakages
- Testing an ODroid U2 as a buildbot, will leave it running for a week
non-stop
- Checking why ClamAV has different output on Chromebook vs.
ODroid/Panda/x86
* ODroid U2
- Testing ODroid vs. Chromebook / SDCard vs. External HD
- ODroid with SDCard is faster than Chromebook with External HD!
- The huge heat-sink, the possibility of adding a fan and its form factor
make it a really good candidate for a buildbot
* Background
- Meetings with ARM, LLVMLinux
- Interviewing potential candidates
- Reviewing & committing patches, discussions, etc.
* Cross-compilation
- Preparing the terrain to start investigation
== Plan ==
Another week off! :D
Progress:
* v7 mach-virt upstreaming:
** sent out an RFC patchset implementing '-cpu host' for QEMU for v7 CPUs
* QEMU maintenance:
** versatile-pb PCI issues came up again; testing kernel patches etc
-- PMM
Is there a way to generate A32 code with the gcc-linaro-aarch64- compilers? I looked at the bare metal and linux 2013.07 versions, but didn't see a way to do this.
Also, the compiler doesn't complain about -mcpu=cortex-a53 or -mcpu=cortex-a57, but I get unknown cpu errors from the assembler for these options. It looks like it is the case today that there is just generic v8 code generation and more specialized code generation will come later. Is that right?
Thanks, Don
== Issues ==
* None
== Progress ==
* Investigate and close lp:1208945 and lp:1210713.
- For lp:1208945, libc.so.6 should be at /lib/arm-linux-gnueabihf.
- For lp:1210713, aufs is not a part of standard linux kernel release.
But aufs is supported by Ubuntu release. So maybe need it for future
releases.
* Conditional compare
- Enhance reassoc pass to handle conditional compare
- Investigating bootstrap issue when expanding conditional compare to
optimized RTL.
* Investigate LDTS tickets about multilib build issues.
- Local builds are OK for Linaro GCC 4.7 and 4.8.
== Plan ==
* Send out the conditional compare patches for review.
== Panned leaves ==
* Aug. 19-20: annual leaves
* Sept. 3-5: internal meeting.
