== Progress ==
Reviewing GDB tests that FAIL due to timeout problems in remote
configuration.
Made some changes to some of the GDB tests that FAIL on arm targets to
check if they work by minor modifications.
Sick Days: Had been sick due to cough n fever and a drop in blood pressure
made me take most part of Thursday and Friday off.
== Plan ==
Get with Matt for Post- Connect work targets.
Review remaining GDB tests that FAIL due to timeout problems in remote
configuration.
Further experiments with GDB test suite to check support for unsupported
tests on arm.
The Linaro Toolchain and Platform Working Groups are pleased to announce
the 2013.03 release of the Linaro Toolchain Binaries, a pre-built version
of Linaro GCC and Linaro GDB that runs on generic Linux or Windows and
targets the glibc Linaro Evaluation Build.
Uses include:
* Cross compiling ARM applications from your laptop
* Remote debugging
* Build the Linux kernel for your board
What's included:
* Linaro GCC 4.7 2013.03
* Linaro GDB 7.5 2012.12
* A statically linked gdbserver
* A system root
* Manuals under share/doc/
The system root contains the basic header files and libraries to link your
programs against.
Interesting changes include:
* gcc updated to 4.7-2013.03:
* Updates to GCC 4.7.2+svn196272
* Includes arm/aarch64-4.7-branch up to svn revision 196225
* A fix for LP #1135633: [linaro regression] alsa-tools FTBFS with error
"unable to find a register to spill in class ‘AREG’"
The Linux version is supported on Ubuntu 10.04.3 and 12.04, Debian 6.0.2,
Fedora 16, openSUSE 12.1, Red Hat Enterprise Linux Workstation 5.7 and
later, and should run on any Linux Standard Base 3.0 compatible
distribution. Please see the README about running on x86_64 hosts.
The Windows version is supported on Windows XP Pro SP3, Windows Vista
Business SP2, and Windows 7 Pro SP1.
The binaries and build scripts are available from:

Short week to ...
== Progress ==
* Configured GCC testsuite to run on the Foundation model.
* Boehm GC AArch64 support:
- Submitted gc integration patch in GCC upstream for review.
- libatomic_ops AArch64 support branch re-tested and merged in mainline.
== Next ==
* AArch64 libunwind support.
== Progress ==
- Closed the blue print for gc-sections implementation since the patch
got upstreamed.
- Opened new blue print for adding more test coverage to gc-sections tests.
- Submitted a patch to enable missed out gc-sections test cases from
ld-elf group.
- Wrote gc-sections test cases for few GOT related relocs.
== Plan ==
- Understand equivalences created during CFG traversal for jump threading.
- Look at GCC code for a simple test case where jump threading is missed out.
- Continue writing gc-sections test cases for remaining relocs.
== Progress ==
- Monday was a public holiday
- Studied benchmarks and analysed the rtl/asm for redundant sign extensions
- Came up with simple test cases based on this (have 6 test cases now)
- Looked at gcc tree documentations and helper macros; tried it by
adding more debug dumps for types at tree level
== Plan ==
- Start with the algorithm for sign extension elimination
- Skipping manual changes at source level/asm level to see the
performance improvement for now.
Short week...
== Progress ==
* Catch up on internal tasks / email that piled up during holidays + Connect
* Resumed work on disable-peeling:
- local benchmarking on snowball
- restarting benchmarks via cbuild for an additional check
== Next ==
* Check benchmark results on disable-peeling
* Have a look at how to dejagnu-ize my Neon intrinsic tests
* Check results of libsanitizer branch
* Check results of 'revert-coalesce' branch
* Check bench results of '4.7-backport-vect-cost-model'
* Check bench results of '4.7-turnoff-64bits-ops'
* Investigate why cbuild did not generate all the comparisons I
expected (*-diff.txt files)
* Check whether 2013.03 release process exposed the same problems I
observed with 2013.02.
Progress (in a 1 day week...):
* qemu maintenance:
** released qemu-linaro 2013.03
** arm-devs pullreq
* VIRT-4 [Guest migration support for KVM]
** audited vexpress code for migration issues: there are a few
devices needing minor cleanup, and one (pflash_cfi01) which
has no migration support at all and needs it writing
* KVM other:
** reviewed virtio-blk refactoring patchset
-- PMM
== Progress ==
* Recuperating from Connect, catching up on email
* Attended David's and Maddog's presentation on Monday
* Investigating Arndale bug (seems to work with new kernel)
- Bootstrapping LLVM works, GCC doesn't
* Reviewing patches upstream (Mans', Tim's, others)
* Fixed three bugs on test-suite that depended on RNGs
- Only two more tests broken only in ARM
- Five others broken on both (but only visible on our bot)
- Nine EH tests that need disabling, for now
== Plan ==
* Tackle the two last ARM specific bugs
* If time allows, clear the other 5
* Try to disable any EH-specific test on ARM
* Start talks about getting an internal binary distribution process going
This is to let you know that the migration of lists.linaro.org has been
successfully completed.
As per the email I sent on Wednesday, it may take some time for the new
address of the server to be seen by your computer. You can check this by
trying to connect to the web site:
http://lists.linaro.org/
If you are able to connect and you do not get an error, this means you are
connecting to the new server and you can send email to the lists.
If you experience any problems after the weekend and you find that you
still cannot connect to the server, please reply to this email to let us
know.
