OK, but then you don't mix some libs/apps with soft and other
apps/libs with hard FP?

No, we never tried that. Sounds scary to me.

And dangerous.  Hard-float and soft-float are ABI incompatible, so you
cannot mix and match obj files and libs compiled with those two options.
They all have to be hard-float or they all have to be soft-float.
Think about a function compiled with hard-float calling a soft-float
libm routine.  The hard-float routine will pass its args in via FP
regs and the soft-float lib routine will be looking for them in the
integer registers.
