== Progress ==
* 4 day week (leave on Thursday)
* Pushed memcpy improvement to newlib.
* Found and fixed ARM IFUNC issue in glibc.
* memcpy merged into bionic but not yet used (see gerrit review).
* Pinged and applied gdb testsuite patch, only one left to apply.
* More work on malloc benchmarking.
* Preparation for Connect.
== Issues ==
* None.
== Plan ==
* Connect all week

Toolchain Working Group, Linaro
== Progress ==
* Buildbots
- Prepared buildbot images, tested, setup is very quick and efficient
- Set up local buildmaster, two buildslaves doing self-hosting tests
- Each slave took 20 minutes setup time, including flashing SDCard
- Failures after a few hours running at 100% @ 1.2GHz @ < 26C
- Reducing to 920MHz does fix the problem, but this is not a solution
- Leaving the two pandas alive during Connect in hope they won't fail
* LNT Lencod
- Following up on Lencod stack corruption, we're closer to a solution
* Dibmod
- Didn't have much time to look at it properly, but my solution was over
simplified
- Will probably only look at it better after Connect
* Chromebook
- Had to re-install Ubuntu on it, using Raring (Saucy didn't work)
- Glad all my data is in the external hard-drive
* Others
- Added a doc about platform-specific tests that usually break the bots
http://llvm.org/docs/TestingGuide.html#platform-specific-tests
- LLVMLinux meeting, cross-compilation with Clang is almost impossible
- Haven't been able to review many patches, thanks to Tim, they kept going!
== Plan ==
* Connect whole next week
== After Connect ==
* Finish implementation AEABI divmod/udivmod calls
* Check why Phoronix result pages are not working
* Put self-hosting bots back on 920MHz mode in the Lab
Progress:
* misc:
** went through "aarch64 preparation" patchset (originally Alex's,
then modified by John), fixed a lot of issues/nits, and sent out
an updated version; this is now I think upstreamable-quality
except that it doesn't provide anything useful on its own.
** looked at the VirtualOpenSystems patchset for v8 KVM support in
QEMU; needs to be reconciled with John's work in the same area.
** Mans' LDA/STL patches now queued in target-arm.next to go upstream
** preparation for Connect
Plans:
* mach-virt
-- PMM
== Issues ==
* None
== Progress ==
* Investigate library dir issue in aarch64-linux-gnu release.
- Crosstool-ng should not link lib64 to lib.
- Eglibc used in Linaro release is too old. No configure to change
lib to lib64.
- Runtime tarball should not assume multiarch (aarch64 gcc does not
support it yet).
- When creating runtime tarball, use lib or lib64 bases on the TARGET.
* Fix misc issues in local conditional compare changes.
* Investigate how to optimize "c == '+' || c == '-'".
== Plan ==
* LCE13: July 8-12.
== Progress ==
* Short week (3 days off sick)
* Aarch64 frame growing downward: sent patch
* A few merges on Rob's behalf after approval by Yvan
* Prepared one more merge request
* Prepared for Connect
* Internal support
== Next ==
* Handle remaining backports for 4.8 release
* Disable peeling: resume work
== Issues ==
* None.
== Progress ==
* OE Launchpad bug #1192953 :
[g++ compilation terminated with error on Linaro-openembedded lamp image]
- Doko submitted a patch for that issue one year ago
- Mailing list pinged
* Launchpad bug #1186218 :
[kernel doesn't boot on Arndale/Nexus with Linaro GCC 4.8]
- Reproduced the build locally
- Need to have access to some hardware for further investigations
* LRA on ARM and AArch64:
- Fixed the issue, compiler now bootstrap
- Testing on-going before submission
* 2013-07 release:
- merge reviews
* LCE13:
- Connect registration done
- flight and hotel booked.
== Plan ==
* Merge review and release preparation
* LRA
== Progress ==
* Re-wrote gdb.dwarf2/dw2-error.exp and gdb.dwarf2/clztest.exp for arm.
* Investigated catch syscall patch in gdb patches to narrow down changes
required for arm.
* Continued with gathering documentation for future visas.
== Plan ==
* Test and fix failures due to optimization code in gdb.dwarf2/clztest.exp
for arm.
* Figure out a way to generate arm assembly for dwarf2/fission* gdb tests
using gcc.
* Further investigation arm requirements by going through catch syscall
patch for gdb on x86.
* Work with James to start UK and US visas for future visits.
Most of Last week spent on internal AMD work.
== Progress ==
* AArch64 LTO and PGO support.
LTO run for coremark and ran coremark on V8 model with and without the patch.
Ran perf on the model against the both the coremark binaries.
For non LTO, retired instructions seems to be less than the LTO one.
And PGO run for coremark did not emit any gcda file. Need to drill down further.
* AAarch64 testing
GCC runs still on going. Experimenting on spawning subtarget tests to
more than one V8 model.
== Plan ==
* Complete gcc testsuite with runs with trunk and trunk+gprof GCC patches.
* Continue LTO and PGO runs for AArch64
==issues==
* libssp support for AArch64
This work is currently in hold. Needed frame layout changes before
restarting.
== Progress ==
* spec2k comparison between ARM and x86
- Specfp on x86 has some failures in trunk
- Trying 4.8 now
- Analysed some of the benchmarks and documenting them
- continuing with the rest.
== Plan ==
* Continue with spec2k comparison between ARM and x86
== Issues ==
* None
== Progress ==
* Investigate big endian toolchain build in Linaro crosstool-ng.
- Fix an aarch64 triple name issue.
- Add Linaro armeb-linux-gnueabihf, aarch64_be-linux-gnu and
aarch64_be-none-elf configs for big endian builds.
- Please find the reference builds at:
http://cbuild.validation.linaro.org/build/crosstool-ng-linaro-1.13.1+bzr258…
* Design a test case for lp1189445 and revise the patch for review.
* Revise the shrink-wrap related fix for pr57637 and send out for review.
* Investigate lp:1194501 and lP:1194123
- lp:1194501 is confirmed a "tail call" issue, and also in trunk pr57731.
- lP:1194123 seams shrink-wrap related, since the case pass with
option -fno-shrink-wrap.
== Plan ==
* Continue on conditional compare.
Best Regards!
