New Revision: 206490
URL: http://svn.freebsd.org/changeset/base/206490

Log:
  While SPARC V9 allows tininess to be detected either before or after
  rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and
  UltraSPARC processors defines that in all cases  tininess is detected
  before rounding therefore rounding up to the smallest normalized number
  should set the underflow flag. This change is needed for using SoftFloat
  on sparc64 for reference purposes.
