For the FPU-less PowerPC (e500) port we previously (6.x) used the SoftFloat lib, but during integration with -current I had lot of problems to make it work (a couple of symbols in libc got 'corupt'), and finally gave up for the gcc level soft-float instead, which seems to work fine.

Hi Rafal,

The libsoftfloat got imported for arm because at the time it happened, gcc
(3.4.6 or something like this) didn't provide softfloat for arm.
Also, last time I tried it, the libgcc softfloat bits behaved strangely,
and gave dd segfaults or funny pings. 
So I gess FreeBSD/arm plans are to get right of the libsoftfloat when the
libgcc bits will work as expected :-)
