lawrence_danna created this revision.
lawrence_danna added reviewers: JDevlieghere, jasonmolenda, labath.
Herald added a project: LLDB.
lawrence_danna added parent revisions: D68962: update ScriptInterpreterPython
to use File, not FILE*, D68960: remove FILE* usage from SBStream.i.
The SWIG typemaps for FILE* are no longer used, so
this patch deletes them.
