Including Bero who's looked at this recently.

Zach, you'd need to use multiarch and have multiple installed libraries so that you could support both hard and soft float ABI. Does Android do anything different / interesting in its image / shared library loader(s)? Dave

Steve,
I'd like you to meet Jim who did the initial hardfloat work. This email contains the results that Jim produced.
I believe that the conclusion was that skia and webkit may benefit, but that such benefits would impose an undue burden on Android's distribution model which tries to create libs that can run on as many architectures as possible.

Jim,
Thanks. Would it be possible to post them by the end of the day?
skia ->
Switch from VFP back to fixed scalar based calculation
Previous configuration enabled ARM VFP for scalar float, but VFP on ARM11 is not as powerful as VFPv3 or NEON.
Reference benchmark: Item Fixed based VFP-based ------------ ----------- --------- Draw Canvas 58.37 fps 58.40 fps Draw Circle 37.48 fps 22.93 fps Draw Circle2 17.14 fps 18.31 fps Draw Rect 17.62 fps 20.69 fps Draw Arc 24.79 fps 27.45 fps Draw Image 19.08 fps 18.73 fps Draw Text 29.22 fps 25.79 fps
Also, have you sync'd up with Mike? He wants to negotiate on your contract.
I sent mail to Mike already. I don't know how to proceed.
