Module Name:src
Committed By:   martin
Date:   Fri Nov 22 17:04:24 UTC 2013

Modified Files:
src/lib/libc/softfloat/bits64: softfloat.c

Log Message:
Fix a cast from the lint cleanup that made small exponents (i.e. values  1)
sign extend wrong and overflow, causing an underflow in all 128 bit sqrt
calculations.
