read_memory_string is redundant and only called in a couple of spots. This patch removes it in favor of target_read_string. gdb/ChangeLog 2020-06-15 Tom Tromey <tromey@adacore.com> * corefile.c (read_memory_string): Remove. * ada-valprint.c (ada_value_print_ptr): Update. * ada-lang.h (ada_tag_name): Change return type. * ada-lang.c (type_from_tag): Update. (ada_tag_name_from_tsd): Change return type. Use target_read_string. (ada_tag_name): Likewise. * gdbcore.h (read_memory_string): Don't declare.
