It is meant to be used to record modules @imported by the current compile unit, so a debugger an import the same modules to replicate this environment before dropping into the expression evaluator. DIModule is a sibling to DINamespace and behaves quite similarly. In addition to the name of the module it also records the module configuration details that are necessary to uniquely identify the module. This includes the configuration macros (e.g., -DNDEBUG), the include path where the module.map file is to be found, and the isysroot. The idea is that the backend will turn this into a DW_TAG_module. http://reviews.llvm.org/D9614 rdar://problem/20965932 llvm-svn: 241017
