== Progress ==
* GCC trunk/4.9 monitoring (2/10)
- still tracking cause of random "interrupted system call" errors
- checked possible regressions
* AArch64 sanitizers (1/10)
- managed to build on board, didn't try to run the tests yet
* Neon intrinsics tests (2/10)
- fixed a couple of bugs in the already upstreamed tests
- continued conversion to GCC testsuite
- support to external user (LLVM based compiler)
* 4.9-2014.12 release (1/10)
- backports+branch reviews
* Misc (4/10)
- meetings, conf-calls, emails....
== Next ==
* GCC trunk/4.9 monitoring
* AArch64 sanitizers
* Neon intrinsics tests
* cbuild2/abe: look at backport and tcwgweb
Holidays: Dec 22nd - Jan 2nd
Apology for sending this out late.
== Progress ==
Debugging ARM gdb watchpoint failures [4/10] [TCWG-567]
-- Prepared a testsuite patch for unsupported tests on ARM
-- Investigation of other failures due to watchpoints installation
rejected through ptrace interface.
QEMU kernel debugging setup [4/10] [TCWG-568]
-- Setup arm Linux kernel debugging to debug watchpoints
Studying arm debug unit architecture versions for possible upgrade to
watchpoint/hwbreak implementation. [1/5] [TCWG-569]
Miscellaneous [1/10]
-- Meetings, Emails etc
-- Follow up on Hong Kong Visa
== Plan ==
Figure out unexplained arm gdb watchpoint rejection from ptrace interface.
More work to figure out a way to debug arm Linux kernel using QEMU
Some further study on arm debug unit architecture versions.
== Progress ==
Holiday [1/10]
Investigated bug #928 [4/10]
. turns out to be invalid implementation of memset in old linux kernels
. raises a question - do we want to provide support for users of old
Linux kernels on new compilers? We could spend a long time rehashing
work the kernel community has already done.
bugs #403/418 [3/10]
. working on fixing error reporting for Aarch64 vldN_lane/vstN_lane
. trickier than expected, but have found a plan to implement this week
Misc [2/10]
== Plan ==
submit patch for #403/418 vldN_lane and work on more intrinsics
== Issues ==
* Validation unusable all week, seems to be operational now.
== Progress ==
* GCC 4.9 2014.12 (5/10)
- Struggle with backports validation,
- everything is in the pipe now ... wait and see
* Misc: (5/10)
- Scripted the GCC revisions management, now able
to track ARM related trunk contribution and fill the backport
spreadsheet, and will be able to generate the release notes.
- Various meetings.
== Plan ==
* Backports
* Branch merge
* Libunwind (AArch64_be review)
Back from Vacation 24, 26, 27 and 28 November. (8/10)
= Progress ==
* TSAN support for Aarch64 (1/10)
* Emails, linaro and AMD status meetings. (1/10)
1-1 with maxim
== Plan ==
* TSAN support for Aarch64.
* Fix Linaro Bug 863
* catchup emails and other discussions
== This week ==
* GCC Modularization Project
- created initial patch for flattening cfgloop.h.
- created initial patch for flattening df.h.
== Next Week ==
- Finalizing patches for cfgloop.h and df.h.
- Continue working on flattening header files.
== Progress ==
* Zero/sign extension elimination with widening types (1/10)
- Addressing comments from the review
* BUG #398 #412 (5/10)
- built kernel revision with provided config and toolchain binary
release to reproduce gcc segafult. Couldn’t reproduce it. Since there
is no more details to reproduce, closed it as cant reproduce.
- Spec2k gcc optimization issue was reproduced and reduced test-case
was created.
- dumps shows that this issue could be related to splitting constants
for early during expand might be the root cause.
* Holiday (4/10)
== Plan ==
* Continue with Zero/sign extension.
* BUG #412
== Planned Leave ==
* 11/12/2014 to 24/12/2014 - 10 days
