This replaces most of the remaining ui_file_xstrdup calls with ui_file_as_string calls. Whenever a call was replaced, that led to a cascade of other necessary adjustments throughout, to make the code use std::string instead of raw pointers. And then whenever I added a std::string as member of a struct, I needed to adjust allocation/destruction of said struct to use new/delete instead of xmalloc/xfree. The stopping point was once gdb built again. These doesn't seem to be a way to reasonably split this out further. Maybe-not-obvious changes: - demangle_for_lookup returns a cleanup today. To get rid of that, and avoid unnecessary string dupping/copying, this introduces a demangle_result_storage type that the caller instantiates and passes to demangle_for_lookup. - Many methods returned a "char *" to indicate that the caller owns the memory and must free it. Those are switched to return a std::string instead. Methods that return a "view" into some internal string return a "const char *" instead. I.e., we only copy/allocate when necessary. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_name_for_lookup, type_as_string): Use and return std::string.
