[Lldb-commits] [PATCH] D59164: [SymbolFileDWARF] Move ElaboratingDIEIterator into implementation file

2019-03-08 Thread Zachary Turner via Phabricator via lldb-commits
zturner created this revision.
zturner added a reviewer: clayborg.

  This is not used outside of the private implementation of the class,
  so hiding in the implementation file is a nice way of simplifying
  the external interface.
