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. > > So what's ARM people view on using SoftFloat vs. gcc soft-float? What are FreeBSD/ARM plans in this regard. > 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 :-) Regards, Olivierhelp
