Hello Erik,
My patch adding ARM assembly soft-float routines to gcc also changes the
default FPA float word ordering for the saner VFP word ordering which is
also the order anyone would expect on a little endian machine.
Problem is that uClibc curently hardwire floats to big endian (FPA) ordering
in all cases.
Please consider the attached patch to fix this problem.
Nicolas
