== Summary == * Continuing on the GCC SMS performace improvement * Continuing on general GDB correctness * Now handles unwinding from inside kernel vector pages * Next is adding unwind information into GLIBC system calls * Decided to take over and upstream QEMU Versatile Express support. Gives us a decent A9 board * First couple of optimised string routines are now in Ubuntu * Have approval for working on libunwind. Beginning this work. * Investigating excessive memory usage when compiling QEMU on ARM (as opposed to targeting ARM) * Continuing with benchmarks.

Hi TC working group,
May I ask what the following means?
"724987https://launchpad.net/bugs/724987: discourage use of NEON on the A8"
Thanks Yves

Hi Yves. This is an optimisation that discourages GCC from using certain NEON instructions that are expensive on the A8 and better done through core registers. It doesn't discourage NEON in general, nor does it mean we have a policy of discouraging NEON on that core.
Hope that answers your question,

Can someone update that bug to point to whatever it is supposed to be pointing to? When I click the lp link it just pops up a dialog saying 'No such product series: 4.5,revno=99353'

Hi Steev. Unfortunately it's broken and has to be that way. This field is used by our patch tracker to link the upstream status to a revision. The format is official way to link to a particular revision in bzr but unfortunately Launchpad doesn't parse it.
