Douglas Gregor	4fc9f3e819	Optimize unqualified/global name lookup in modules by introducing a ... generational scheme for identifiers that avoids searching the hash tables of a given module more than once for a given identifier. Previously, loading any new module invalidated all of the previous lookup results for all identifiers, causing us to perform the lookups repeatedly. llvm-svn: 148412	2012-01-18 20:56:22 +00:00
Douglas Gregor	de3ef502a9	Promote ModuleMap::Module to a namespace-scope class in the Basic ... library, since modules cut across all of the libraries. Rename serialization::Module to serialization::ModuleFile to side-step the annoying naming conflict. Prune a bunch of ModuleMap.h includes that are no longer needed (most files only needed the Module type). llvm-svn: 145538	2011-11-30 23:21:26 +00:00
Douglas Gregor	9d7c1a2a18	Add support for viewing the module graph via Graphviz, for debugging ... purposes. llvm-svn: 141697	2011-10-11 19:27:55 +00:00
Douglas Gregor	d44252ec03	Factor the Module and ModuleManager classes out into separate headers ... and .cpp files, since ASTReader.cpp was getting way too large. No functionality change. llvm-svn: 138582	2011-08-25 20:47:51 +00:00
