10/// Placeholder plugin for the save core functionality.
11///
12/// ObjectFileMinidump is created only to be able to save minidump core files
13/// from existing processes with the ObjectFileMinidump::SaveCore function.
14/// Minidump files are not ObjectFile objects, but they are core files and
15/// currently LLDB's ObjectFile plug-ins handle emitting core files. If the
16/// core file saving ever moves into a new plug-in type within LLDB, this code
17/// should move as well, but for now this is the best place architecturally.
