* doublest.c (convert_floatformat_to_doublest): Use
floatformat_classify. (floatformat_is_nan): Rename to... (floatformat_classify): ...this. Return more information. * doublest.h (enum float_kind): New. (floatformat_is_nan): Replace prototype... (floatformat_classify): ...with this one. * valprint.c (print_floating): Use floatformat_classify. Handle infinity. * gdb.base/infnan.c, gdb.base/infnan.exp: New files.
