    sys/amd64/include    ieeefp.h 
  Log:
  Extend the machine/ieeefp.h that was inherited from i386 to support
  the SSE mxcsr register as well.  Since gcc will intermix SSE2 and x87
  FP code, the fpsetround() etc mode had better be the same.
  
  There are hooks to enable these inlines to be instantiated inside libc
  for non-gcc or C++ callers. (g++ doesn't like the inlines that tried
  to extract an integer and convert it to an enum).
