  EABI to my mind only helps in ultra-tight embedded environments, which 
I don't think exist anymore. 8-byte vs 16-byte stack alignment isn't 
going to help anyone.

  And if embedded environments are using a lot of soft-float, they are 
running on the wrong type of CPU. Trapping to the kernel should be 
infrequent, and it does allow a single ABI for all processor types.

  GCC will generate floating point instructions for data copying in 
contrived situations, but there are none in base FreeBSD/ppc.

  My $0.02 ..

later,

Peter.
