== Plan ==
* Back on backports
cbuild2 benchmarking - TCWG-360 [5/10]
* Fixed some bugs and did some general tidying up
* Pulled SPEC2000 into my framework
* Did some test runs on local machines, looks promising
libm exercising - TCWG-558 [3/10]
* Much fiddling with one benchmark (MCB)
* Experimented, thought about methodology
Meetings/mail/etc - [2/10]
=Plan=
cbuild2 benchmarking
* Tweak eembc - it worked before, but spec forced me to change the
scripts a little
* Test in LAVA/new TCWG infrastructure when available
* Test repeatability (depends on above)
* Possibly have another go at building tools on AArch64
libm exerising
* Work through the most interesting benchmarks with a fixed method
* Hopefully reach the end and do some analysis
= Progress ==
* TSAN support for Aarch64 (4/10)
* Fix Linaro Bug 863,869 - reproduced them. Working on fixing 863 (1/10)
* Misc [3/10]
Emails, linaro and AMD status meetings.
1-1 with inline mangers (Mev, Ryan).
1-1 with christophe.
* 11/11/2014 Leave (2/10)
The task on "Debug and understand the inline differences trunk vs linaro
compiler for core mark at -O3 with LTO + PGO" is on hold now.
== Plan ==
* TSAN support for Aarch64.
* Fix Linaro Bug 863
* AMD internal event on 17/11/2014.
== Progress ==
* Zero/sign extension elimination with widening types (5/10)
- Addressing comments from the review
* Improve block memory operations by GCC (TCWG-142 - 5/10)
- Looked at gcc/glibc implementations
- Experimented with x86_64 vs ARM and found different implementation
decisions
- Discussed work items
== Plan ==
* Continue with improve block memory operations by GCC.
* Continue with Zero/sign extension.
== Progress ==
* Building an ILP32 toolchain for AArch64 (5/10, TCWG-559)
* Investigate ARM port of lld (3/10)
* Email, meetings, etc. (2/10)
== Issues ==
* None
== Plan ==
* Further work on ILP32 toolchain
* LLD

1 day off (2/10)
== Progress ==
* Linaro GCC 4.8
- updated branch merge, to include the latest errata-related backport
- added Michael's backport for bug #534.
* GCC trunk/4.9 cross-validation (2/10)
- updated vbic/vorn tests patch
- trying to track down cause of spurious 'interrupted system call'
errors in the ST Compute Farm
* AArch64 sanitizer (1/10)
- After discussing with Arnd, the kernel patch causing trouble to
libsanitizer should also be backported to stable kernel branches. This
makes a compiler test based on kernel version impracticable.
- Shared this feedback with sanitizer maintainers, got no feedback.
- libsanitizer maintainers have updated GCC's snapshot with a more
recent version:
- GCC trunk now requires updated kernel headers for aarch64
- reported regressions when the compiler generates Thumb code
(incomplete backtrace)
* Neon intrinsics tests (2/10)
- submitted a series of 9 new tests.
- looking at vldX bugs on aarch64_be, along with ARM's incomplete patches.
* cbuild2
- no progress
* Misc (3/10)
- calls, meetings, support
== Next ==
* AArch64 sanitizers
* Neon intrinsics
* cbuild2 (improve backport-test and tcwgweb)
The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2014.11
stable release of both Linaro GCC 4.9 and Linaro GCC 4.8 source packages.
With the imminent release of ARMv8 hardware and the recent release of the
GCC 4.9 compiler the Linaro TCWG will be focusing on stabilization and
performance of the compiler as the FSF GCC compiler. The Linaro TCWG provides
stable[1] quarterly releases and monthly engineering[2] releases.
Linaro GCC 4.9 2014.11 is the eighth Linaro GCC source package release and
second stable one in the 4.9 series. It is based on FSF GCC4.9.3-pre+svn216979
and includes performance improvements and bug fixes.
Interesting changes in this GCC source package release include:
* Updates to GCC 4.9.3-pre+svn216979
* Backport of [AArch64] Fix ILP32 ld.so
* Add new Linaro release macros : __LINARO_RELEASE__ and __LINARO_SPIN__
Linaro GCC 4.8 2014.11 is the fifteenth release in the 4.8 series and second
one since entering maintenance. Based off the latest GCC 4.8.4-pre+svn217270
release, it includes performance improvements and bug fixes.
Interesting changes in this GCC source package release include:
* Linaro bugzilla PR fixed : #307, #534
* Updates to GCC 4.8.4-pre+svn217270
* Add new Linaro release macros : __LINARO_RELEASE__ and __LINARO_SPIN__

[1] Stable source package releases are defined as releases where the full Linaro
Toolchain validation plan is executed.
[2] Engineering source package releases are defined as releases where the
compiler is only put through unit-testing and full validation is not
performed.
