New Revision: 215823
URL: http://svn.freebsd.org/changeset/base/215823

Log:
  Use unambiguous inline assembly to load a float variable.  GNU as
  silently converts 'fld' to 'flds', without taking the actual variable
  type into account (!), but clang's integrated assembler rightfully
  complains about it.
  
  Discussed with:	cperciva
