In a thread on comp.lang.c, it was pointed out that softfloat has a bug and in checking src/lib/libc/softfloat I confimed the issue is present in FreeBSD. What I hae not confirmed is whether or not it is possible to hit this bug. In fact, it may only hit arm and mips. Anyway, here's the patch Index: softfloat/bits64/softfloat-macros =================================================================== --- softfloat/bits64/softfloat-macros (revision 275211) +++ softfloat/bits64/softfloat-macros (working copy) _at__at_ -157,7 +157,7 _at__at_ z0 = a0>>count; } else { - z1 = ( count < 64 ) ? ( a0>>( count & 63 ) ) : 0; + z1 = ( count < 128 ) ? ( a0>>( count & 63 ) ) : 0; z0 = 0; } *z1Ptr = z1; -- SteveReceived on Fri Nov 28 2014 - 17:34:23 UTC
