  23 /* Does the current host support the GETFPXREGS request?  The system header
  24    file may or may not define it, but even if it is defined, the kernel
  25    will return EIO if it's running on a pre-SSE processor.
  26
  27    Initially this will be TRIBOOL_UNKNOWN and should be changed to
  28    TRIBOOL_FALSE if the ptrace call is attempted and fails or changed to
  29    TRIBOOL_TRUE if the ptrace call is attempted and succeeds.
  30
  31    My instinct is to attach this to some architecture- or target-specific
  32    data structure, but really, a particular GDB process can only run on top
  33    of one kernel at a time.  So it's okay - for this to be a global
  34    variable.  */
