inlinevirtual

Add passes to the specified pass manager to get the specified file emitted.

Typically this will involve several steps of code generation. This method should return true if emission of this file type is not supported, or false on success. MMIWP is an optional parameter that, if set to non-nullptr, will be used to set the MachineModuloInfo for this PM.
