Re: Building gcc-linaro 4.6 2011.10 on ubuntu 11.10 32bit for cortex-a9

2011-10-25 Thread Bruno Niklaus 
Hi Michael,

thanks for the input.

i get it compiled with using crosstool-ng & this link:
https://wiki.linaro.org/WorkingGroups/ToolChain/Using/CrosstoolNg

Toolchain Connect sessions

2011-10-25 Thread Michael Hope 
Hi there.  Connect is just around the corner.  Have a look at:
 https://wiki.linaro.org/MichaelHope/Sandbox/Q4.11Plans

for a summary of the toolchain sessions and hacking topics.

It would be great to have kernel and OCTO input in the ARM STM driver,
Kernel debugging, and KVM sessions.

Performance improvements hacking time at Connect Q4.11

2011-10-25 Thread Ramana Radhakrishnan 
Hi Folks,

I've been trying to capture what we want to do in terms of hacking
time and some of the performance related backlog that we have in the
system.  I have done so here.

https://wiki.linaro.org/RamanaRadhakrishnan/Sandbox/Q411ConnectGCCPerfPlan

I'm on vacation tomorrow but should be picking email for sometime
during the day.

Thoughts about what else we could be doing in this area or if there's
a better way we could use our hacking time.

cheers
Ramana

Toolchain performance call during connect.

2011-10-25 Thread Ramana Radhakrishnan 
Hi Folks,

Draft agenda for the performance meeting next week at Connect -
https://blueprints.launchpad.net/gcc-linaro/+spec/linaro-toolchain-performance-meeting

Are there any topics that people would like to bring up during this
meeting other than the ones listed here ? I suspect that we'll
probably just have about 10-15 minutes for a topic in this case. I am
not considering discussing PGO related stuff in this session given
that we've got another session in which we can discuss this.

Thoughts ?

cheers
Ramana
