* gc sections tests
Completed adding gc-section test cases.
1. TLS and GOT tests.
http://sourceware.org/ml/binutils/2013-03/msg00273.html
2. PLT tests.
http://sourceware.org/ml/binutils/2013-03/msg00273.html
* Evaluate gprof work.
There is one function hook "find_call" which is machine dependent and
is written for i386.c/sparc
Then there are changes in configure.in to add architecture details.
* 1-1 with Matt.
== Plan ==
Continue gprof support work for Aarch64
== Progress ==
* Buildbots
- All ARM build-bots GREEN! Hurray!!! :D
- Improving sort comparison functions makes output reproducible on all
machines
- Fixed fpcmp, which fixes sqlite3 report
- A bad commit broke lots of tests, reverted
- Adding a self-hosting check-all Pandaboard
- In theory, it works, but config is not perfect yet
* Arndale
- Suse image is not stable enough, installed Linaro (325)
- Fathi got GCC bootstrapping with it, should work
- Installed a heat-sink on the board, should reduce problems
- Still got network issues, may be the mac address
- Someone could liaise with Dave Pigott to get a new MAC on the DHCP
* EuroLLVM 2013
- Badges, finishing touches
== Plan ==
* Holidays next week, then
* Check with Galina about Beagle bots
* Finish Panda self-host + test-suite A9 bot
* Gather info and hardware for 3.3 release tests
* Plan for the future!
== Progress ==
* Short week (2 days)
* Tested memcpy on big endian.
* Updated newlib memcpy patch.
* More digging into glibc IFUNC.
== Issues ==
* None.
== Plan ==
* Try and get newlib mempcy patch accepted.
* IFUNC...

* Disable-peeling:
- Still waiting for the results from cbuild. Because of many merges
(pre-release week), there are a lot of jobs in the queue :-(
* Libsanitizer:
- tried to understand why isatty(2) returns true when executing the
testsuite via qemu.
* Neon intrinsics codegen:
- benchmarking in bare-machine shows that GCC is actually ~5% faster
than RVCT on this sample codec.
- to be further discussed internally
* Neon intrinsics testsuite:
- looking at FP16 support.
* Turnoff 64bits ops in Neon:
- backport in 4.8 done by Matt during the release merges.
* Arndale: a few attempts to use it, but it's still unstable.
* Internal support
== Next ==
* Disable-peeling: Analyze bench results when available.
* Revert-coalesce-vars: Analyze bench results when available.
* Libsanitizer: contine isatty(2) study wrt qemu/expect.
* Neon intrinsics: check internally for other codecs
[short week, two days]
Progress:
* qemu maintenance
** arm-devs pull request (and associated code review, etc)
* VIRT-4 [Guest migration support for KVM]
** VIRT-49: implement cp15 sync with kernel
*** some forward motion, but partway through realised some work
I thought had been committed last year hadn't been, so:
** VIRT-73
*** new work item, covering updating the migration state for the
CPU itself to use VMState structures, by updating, testing
and tweaking some patches from Juan Quintela from last year
*** have done the 'update' part; tests and tweaks still todo

Summary:
* Investigate conditional compare.
Details:
1. Expand conditional compare as TRUTH_AND_EXPR/TRUTH_IOR_EXPR for tests.
2. Test tree-level changes for conditional compare.
* Fix/workaround most ICE issues in regression tests.
* Still some fails which expected VRP can optimize the cases.
3. Try to build Coremark and find that conditional compare does block
optimizations, which leads to worse performance.
Plan:
* Investigate VRP and other optimizations to handle conditional compare.
* Raise the propose for upstream discussion.
Planned leaves:
* April 4-8: Chinese Ching Ming Festival and annual leaves.
* April 12: Internal team event.
* April 16-17: Internal training.
Best Regards!

Started investigating gdb test cases that are failing on
arm-remote gdbserver configuration.
Completed investigation on all timeout gdb test cases failures in
arm-remote gdbserver configuration.
Setup a ubuntu test machine for gdb testing on x86_64 in
remote gdbserver configuration.
Initiated visa process for Ireland and sent requests for required documents
to Arwen.
*** No blue-print available to log work in JIRA.
== Plan ==
Complete investigation of all failure gdb test cases on arm-remote
gdbserver configuration.
Run gdb test suite in x86_64 remote gdbserver configuration and compare
with all other configurations already tested including arm remote to figure
out any similar failures while running test suite remotely on two different
machines.
Book travel to Ireland and complete visa process.
Summary:
* Investigate how to expand conditional compare.
Details:
1. Try to expand conditional compare to RTL
* It seams hard to expand conditional compare to just one cond_exec
insn during expand, since it has to know the cc (GT, LT, etc) set from
previous instruction and tell the later instruction which cc (GT, LT,
etc) it set.
* Try to add new RTL key-word and insn pattern.
2. Follow up Linaro toolchain binaries bug in Yocto build: 1159392,
1161348 and 1161351.
Plan:
* Generate asm for conditional compare.
Planned leaves:
* April 4-8: Chinese Ching Ming Festival and annual leaves.
* April 12: Internal team event.
* April 16-17: Internal training.
Best Regards!

- Very short work week. I was on leave last Wednesday and Thursday (27th
and 28th).
- Posted patch for gc-section tests for TLS and got related relocs.
- Discussing with Marcus on patch I wrote for gc section tests on PLT
related relocs.
== Plan ==
- Post patch for gc section tests for PLT relocs.
- Complete gc section tests for other generic cases.
- Understand and evaluate gprof support work for Aarch64
