== Progress ==
* Connect recovery [6/10]
Very short week short week travel back from connect
22nd - 23rd travel.
25th - sick leave.
* Backport - Bug 676 - CSE did not optimize the redundant cmp
instruction on aarch64 [2/10].
Checked the issue by building latest trunk, linaro branch and by
adding the patch on top of linaro branch . Validated the code
generated at -O2 and it seemed to be optimal and bug does not occur.
Discussed with Christophe and decided to rebackport it along with
211881. It was reverted because of an libjava bug which is fixed in
211881. Used back flip to back port, git review was not automatically
working. So manually amended by adding the change log for combined
backport of revisions 209643 and 211881.
* Misc [2/10]
Prepared notes on LCU14 to AMD team.
Examined spec benchmark in internal Aarch64 hardware for a support issue.
Internal meeting and 1-1 with manager.
== Plan ==
* Coremark benchmark and report for PGO and PGO + LTO
* Get profiles on trunk for PGO and PGO + LTO
* 29/9/2014 - Personal day off
* 2/10/2014 - 3/10/2014- Dusserra Holidays Leave
== Progress ==
* Connect recovery [4/10]
* NEON load/stores (TCWG-516 [5/10])
. initial review of my vldN_lane asm()->__builtin patches is promising
. the other patches for other loads/stores are wrong. Have been investigating
(with upstream) how much bigger the can of worms is.
* Misc [1/10]
. LCA15 travel
. bug investigation (#405)
== Plan ==
* more NEON load/store
Short week, 2 days holiday (4/10)
== Progress ==
* GCC trunk/4.9 cross-validation (2/10)
- reported a few new FAILs
- trying to allocate time to fix new FAILs introduced in the 4.9
branch on devirt-28a.C, mostly because a testsuite configuration
problem.
- fixed reporting of email-driven validations
* AArch64 libsanitizer
- finally committed asan+ubsan support for AArch64!
* Misc (4/10)
* email catch-up
* calls/meetings
* updated backports speadsheet, backlog now > 75
* bugzilla management
== Next ==
* GCC trunk/4.9 cross-validation:
- actually reproduce+propose fixes for a couple of regressions
recently observed
* AArch64 thread sanitizer
* Neon intrinsic tests
* Analyze failures in Backport job in Jenkins
* Analyze differences in validation results between using shared libs
and static libs
I just updated the stable branch to match master, which in my testing
has been reliable and stable. I also changed the following Jenkins jobs
to use the stable branch: Backport, BuildFarm, BinaryRelease, SourceRelease.
Note that now any Jenkins job that runs tests and validates them using
the tcwgweb.sh script, the build and test run may succeed, but if there
are any regressions, the dot will be Red now instead of Green. This
primarily effects the Backport and the Release jobs.

Hi Sugar,
the toolchain you need is the one with the aarch64-linux-gnu triplet.

Hi all,
I'm using ct-ng to rebuild Linaro toolchain (arm-linux-gnueabihf ) for Linux kernel 2.6.36.
Ct-ng version: ct-ng-linaro-1.13.1-4.8-2014.01-01
There is a “FATAL: Kernel too old” message after mounting the rootfs. It turns out the default config using pre-built sysroot from Linaro website. After setting " CT_PREBUILT_SYSROOT=n" to build sysroot with lower kernel version, I get the following error:
[EXTRA] Building final compiler
[ERROR] /projects/broadcom-linux/joelz/opt/gcc-linaro-arm-linux-2.6-gnueabihf/arm-linux-gnueabihf/libc/usr/include/gnu/stubs.h:7:29: fatal error: gnu/stubs-soft.h: No such file or directory
[ERROR] make[5]: *** [_muldi3.o] Error 1
[ERROR] make[4]: *** [multi-do] Error 1
I tried to put " -mfloat-abi=hard" as CFLAG in different place, still can't pass this error.
If you have any idea how to fix it, please let me know.
Thanks,
Joel
