Wiederhake, Tim Aug. 11, 2017, 11:06 a.m. UTC 
  From: Bernhard Heckel <bernhard.heckel@intel.com>

Print base-class of an extended type when doing a ptype.

xxxx-yy-zz  Bernhard Heckel  <bernhard.heckel@intel.com>

gdb/ChangeLog:
	* gdb/f-typeprint.c (f_type_print_derivation_info): New function.
	(f_type_print_base): Print baseclass info.

gdb/testsuite/ChangeLog:
	* gdb.fortran/oop_extend_type.exp: Adapt expected results.
