== Bug triaging == * Bug 745843 (vtk ftbfs) got it down to a bad arm/thumb transition - identified as a linker error and handed off to RichardS * Bug 758082 (augeas ftbfs) tracked it down to overwrite of a parameter in a variadic function before it got stacked; identified by Ramana as another instance of the shrink-wrap bug. * Bug 745861 (petsc ftbfs) isolated the collection of different mpi related problems this is hitting; really need to find an mpi expert on this * Bug 745863 & bug 745891 (ftbfs's) - both were compilations that timed out; verified this was due to using lots of RAM and also using lots of RAM on x86 (> ~500MB) - marked as invalid until the build farm grows more RAM * Bug 757427 gconf seg fault - failed to reproduce under various tests (although Michael has now managed to catch it in the act)

== Optimisation == * neon memcpy tweeking; added prefetches and unrolled the core loop - now comparable perf to bionic memcpy in most cases (slower on misaligned destination, faster in other cases) * tweaked latrace to print address/length of argument strings so I can get some stats on routine usage.
