Detailed Description

This class provides the core functionality of linking in LLVM. It keeps a pointer to the merged module so far. It doesn't take ownership of the module since it is assumed that the user of this class will want to do something with it after the linking.

Link Src into the composite. The source is destroyed if Mode is DestroySource and preserved if it is PreserveSource. If ErrorMsg is not null, information about any error is written to it. Returns true on error.

LinkModules - This function links two modules together, with the resulting Dest module modified to be the composite of the two input modules. If an error occurs, true is returned and ErrorMsg (if not null) is set to indicate the problem. Upon failure, the Dest module could be in a modified state, and shouldn't be relied on to be consistent.
