When you call a procedure, in hardfp you put floating point values in floating point registers. In softfp you put them in integer registers for ancient compatibility reasons.

Hardfp is faster due to code doesn't have to move floating point values first from a floating point register into an integer one and then back again upon function call.

Strictly speaking there's also the hwcaps way, which would rock if it weren't for the ARM ABI issues.

Thank you all for your responses.

I wonder then, how is Meego CE so slow in the N900 if it's taking advantage of hardfp, newer kernel and gcc and better TI drivers.
