Incidentally, this ties into the question sent earlier this week which had to do with Nico's work item in:

https://blueprints.launchpad.net/linux-linaro/+spec/other-kernel-thumb2

Which IIRC Nico says probably isn't worth it, right?

I thought dmart had done a lot of that?

I don't see the connection between Thumb2 and memcpy performance. Thumb2 can do anything 32-bit ARM can.

Well, the work item above is also about providing optimized memory routines that come out of the TCWG; if NEON isn't interesting, are any of the optimized Thumb2 versions that the toolchain team worked on that are worth looking at?
