Subject: gdb/dwarf: make read_cutu_die_from_dwo a method of cutu_reader
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d1a5224cd3be966d4aecb195405556e66b534206;p=thirdparty%2Fbinutils-gdb.git

gdb/dwarf: make read_cutu_die_from_dwo a method of cutu_reader

read_cutu_die_from_dwo is only used as a helper to cutu_reader, so make
it a private method of cutu_reader.

Remove the "result_reader" parameter, because it's always "this".
