JDevlieghere created this revision.
JDevlieghere added reviewers: clayborg, labath.
JDevlieghere added a parent revision: D79115: [lldb/API] Move
SBCommandInterpreterRunOption in its own header. (NFC).
JDevlieghere added a child revision: D78825: [lldb/Driver] Exit with a non-zero
exit code in batch mode when stopping because of an error..
This adds an `RunCommandInterpreter` overload that returns an instance of
`SBCommandInterpreterRunResults`. The goal is to avoid having to add more and
more overloads when we need more output arguments.
