== This week ==
Backported Launchpad 1234146 - Bad Neon intrinsics code gen when using
ld4/st4 on AArch64 (2/10)
Bug Investigations (4/10)
Launchpad Bug 640521 - Incorrect function prologue with Thumb-1
high register variable
Launchpad Bug 1318831 - Invalid unpoisoning of stack redzones on ARM
Launchpad bug 771832 - bogus reference to unused symbols
Launchpad cleanup (4/10)
- 1305042 - Changed status to invalid
- 634731 - Marked as won't fix for older releases. Improved code
generated for 4.8 and 4.9
- 637882 - Marked as won't fix for older releases. Improved code
generated for 4.8 and 4.9
- 638687 - Changed status to invalid. Code for alloca is correct
and alignment is necessary
- 1312931 - Could not verify.
- 772085 - Marked as won't fix for older releases. Fixed in 4.8 and 4.9
- 1225317 - Marked as incomplete due to lack of test case
== Next week ==
Vacation
== Future ==
No Plans.
== Issues ==
* None
== Progress ==
* CARD-1162 : Linaro GCC 4.9 and CARD-1355 : stabilization and
optimization effort for ARMv8-a (8/10)
- Put the backporting script on https://git.linaro.org/toolchain/backflip.git
(documentation still needed)
- FSF branch merges for 4.9 and 4.8
- Backported requested fixes in 4.9
- Validate merges and some backports in cbuildv1
- Looked at the different results we have in cbuildv2 and cbuildv1
- Still some issues in Jenkins (build crash or are stuck)
- 40 backports stiil need validation
* Misc: (2/10)
o Various meetings.
== Next ==
* Complete FSF branch merges and release 4.9-2014.06
* Document backporting script usage
* Continue feedback and help with the validation
== Issues ==
* None.
== Progress ==
* One day off.
* Clean up and test loop2-invariant heuristic tune patches (TCWG-469, 6/10).
* Rebase conditional compare patches and split them into smaller ones
(TCWG-488, 2/10).
== Plans ==
* Send out loop2-invariant heuristic tuning patches for review.
* Rework on the conditional compare patches.
== Progress ==
* Toolchain (CARD-862 0/10)
- Some investigations on LLVM Linkers
* Background (10/10)
- Code review, meetings, discussions, etc.
- Cleaned up the rack, drown a map
- Jenkins Chromebooks with native Arch Linux
- Failures and problems ensued...
- More time wasted on APMs, but some progress was made
- All Chromebooks had I/O errors on SD cards, starting over
== Plan ==
Spend the weekend and the next week re-flashing Chromebooks
== Progress ==
* GCC trunk cross-validation (CARD-647) (6/10)
- recent LRA change to fix AArch64 compiler causes huge memory consumption.
- this has caused my validations to crash several servers, and I had
to stop them
until I could restart reliably.
- so far unable to restore them
- trying to test LRA tentative fix separately, but results are unreliable too
- tested Thomas Preud'homme patch (bswap-2.c), luckily before
everything became unstable.
* GCC 4.9 branch cross-validation (CARD-647) (1/10)
- validation scripts needed some adaptations to handle the 4.9-branch
- not running yet, until the trunk problems are solved
* Neon intrinsic tests (CARD-????) (1/10)
- submitted patch series containing 40 test files (total will be 136)
* AArch64 libsanitizer support (TCGW-58)
- qemu still needs a patch of mine which I thought had been
committed since February..
- once patched, the sanitizer tests now start executing but lead to
SEGV+timeout
* Misc (meetings, conf-calls, ...) (2/10)
== Next ==
* short week (Monday off, lots of external constraints)
* GCC cross-validation:
- hopefully fix unstability and restore the automatic validations of
trunk + start those of 4.9 branch
- try to actually start mail-driven robot to validate patches
* Neon intrinsics tests: handle feedback
* AArch64 libsanitizer support: look at why tests fail
== Progress ==
* Holiday Monday and Tuesday (4/10)
* Write some scripts to graph malloc app benchmark results (1/10, TCWG-418)
* Patch review and testing (2/10)
* Released eglibc 2.19 2014.06, binutils 2.24.0 2014.06 and gdb 7.7.1
2014.06 (3/10)
== Issues ==
* None
== Plan ==
* Get wg boards running for validation
* More malloc benchmarking

== Week of June 2nd ==
- Toolchain testing improvements (CARD-1378, 8/10)
-- Implemented schroot testing inside cbuild2. This will allow both Jenkins automation and developers to use schroot testing approach.
-- Automated board configuration for schroot testing.
-- Started cleaning up and committing my testing changes to cbuild2 and dejagnu.
- Various discussions (1/10)
- NZ public holiday (2/10)
- Celebrated! My! Happy! Birthday!

== Week of May 26th ==
- Toolchain testing improvements (CARD-1378, 8/10)
-- Prototyped parallelization of testing across several ARM board. Turns out that striping tests across target boards does not give much as host is the bottleneck in our setups.
-- Prototyped testing using GCC's shared libraries and newly-built sysroot (instead of using system libraries on the target).
-- Prototyped testing using schroots -- this appears the way to go about our toolchain testing. For each test run a schroot session is started on the board, complete with a dedicated SSH server and freshly-built sysroot. After testing is done schroot session is closed and everything is cleaned up including disk files and stray processes.
- Various discussions (2/10)
