Summary: As per the following link, the "--" separator can appear between the options and parameters of any MI command. Previously this separator was only handled by the `-data-disassemble` MI command. I have moved the relevant code into `CMICmdBase` so that any MI command can handle the aforementioned separator. https://sourceware.org/gdb/onlinedocs/gdb/GDB_002fMI-Input-Syntax.html#GDB_002fMI-Input-Syntax Reviewers: ki.stfu Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D14197 llvm-svn: 251793
