I've put the agenda for Monday's call at:
https://wiki.linaro.org/WorkingGroups/ToolChain/Meetings/2012-05-07
which is:
* Review action items from last meeting
* Connect sessions:
* GDB for Android
* GCC performance call - Live!
* KVM performance
* Renderscript
* Android benchmarking
I've made a couple of changes to the processing of benchmark results.
The server now automatically tabulates the raw results like:
http://ex.seabright.co.nz/benchmarks/gcc-linaro-4.7+bzr114974/logs/armv7l-natty-cbuild292-tcpanda02-cortexa9r1/benchmarks.txt
diffbench[1] can now take a URL instea
I've done some minor updates to the instructions for working with
gcc-linaro, bzr, and merge requests at:
https://wiki.linaro.org/WorkingGroups/ToolChain/BzrTips
The interesting changes are using:
* bzr commit --fixes=lp: to link a branch to a bug number
* bzr branch --hardlink to cut down
Ramana,
Can you suggest the flags used for optimal vectorization on A15 using GNU GCC
4.7.
Perhaps specific optimization flags for A15 would also help

Actually its not hanging, I tried to run it in isolation.

That means degradation of -1645.28%

Thanks for trying it out - I hadn't really tried it out when I had
sent the mail. Uli is planning to look into these in the next few
days.
