== Progress ==
* Backport
Tested and backported patch written to CSE optmize compares.
http://gcc.gnu.org/ml/gcc-patches/2013-02/msg00015.html
Ran GCC regression suite with ARMV8 foundation model for aarch64-none-elf
* Implementing GC sections support in bintuils
Had a quick look at changes need to be added.
Reading about relocations that needed to considered for
elf_backend_gc_sweep_hook
* Tried using Cbuild for buildign and testing gcc4.7 aarch64 branch.
ssh keys are not in sync. I am getting permission denied.
Cheking with David and Andy in valdation team.
Misc
* Attend tool chain weekly meet, and stand up call
* Attend usual AMD meetings
* Performed one x86_64 AMD task
* Booked tickets, hotel and got invite letter for Linaro connect.
== Next week ==
* Complete Cbuild experiments to test gcc svn aarch64 4.7 branch.
* Continue gc section support. Implement elf_backend_gc_sweep_hook
== Progress ==
* 64-bits ops in Neon: No news from upstream.
* vectorizer cost model: added possibility to tune the problem by
processor type.
* smin-umin: regression actually caused by a previous patch brought
when merging bswap16 support. Investigation on-going.
* managed to run spec2k on local board. Need to upload tools compiled
for hf platform.
* tcpanda heat problems: GCC testsuite passed.
* hot-cold partitioning: posted a follow-up to google patches on gcc-patches.
* looked at some codecs needing improvements (Neon intrinsics usage)
* feedback on lava/cbuild integration
* hotel/plane booked for Connect.
== Next ==
* handle 64-bits bitops in Neon feedback from upstream if any
* smin-umin: check bench results with probable culprit patch reverted.
Will need investigation on trunk too.
* vectorizer cost model: check bench results
* get more codecs sample codes.
Activity:
* calls and meetings
* last bits and pieces of ARM QEMU patches sent prior to upstream
1.4 hardfreeze
* continuing fixes for running a 3.8-rc4 vexpress kernel on QEMU:
* refactored the way we handle SYS_CFG vexpress registers so it's
possible to reasonably add support for more of them
* put together a basic implementation of the various regs
we're missing (oscillator, voltage, and some misc)
* ideally this would be done via variable-length qdev array
properties; started looking at how hard those would be to implement
* investigated linux-user bug where an edge case in use of
get_user_u32() had accidentally been broken; sent patch
* all travel/hotels now booked for Connect
-- PMM
== Progress ==
* Welcomed Omair to the team working on GDB
* Starting investigating cortex-a9 bootstrap failure
* Blueprints updating
* Preparing for two new starters next week
== Next week ==
* Welcome two new members to the team.
* Finish cortex-a9 bootstrapping investigations
== Future ==
* Run HOT/COLD partitioning benchmarks
* Analyse ARM results
* On x86_64 to see what the actual benefit we could get
* fix-gcc-multiarch-testing
* Come up with strawman proposal for updating testsuite to handle
testing with varying command-line options.
