Re: Cross-compiling standard utilities for 860

You have to be careful here.  If you choose to use the in-line

mix programs that use the kernel FPU emulation and also in-line
software floating-point.  The kernel works out of the floating
point register area in the TSS, while the software float assigns
real processor registers (and other memory locations) to contain
the floating-point values.

I am aware that  I  cannot  mix  this  WITHIN  ONE  application,  for
instance  compiling  the  app  with  soft-float and linking against a
library that uses the kernel FPU emulation.

Are there really problems when running soft-float only  and  FPU  emu
only applications on the same machine? I did not expect any...

Anyone who isn't confused here doesn't really know what's going on.
