2010-12-20Implement basic support for template instantiation of pack expansionsDouglas Gregor
whose patterns are template arguments. We can now instantiate, e.g., typedef tuple<pair<OuterTypes, InnerTypes>...> type; where OuterTypes and InnerTypes are template type parameter packs. There is a horrible inefficiency in TemplateArgumentLoc::getPackExpansionPattern(), where we need to create copies of TypeLoc data because our interfaces traffic in TypeSourceInfo pointers where they should traffic in TypeLocs instead. I've isolated in efficiency in this one routine; once we refactor our interfaces to traffic in TypeLocs, we can eliminate it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122278 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-12Move the functionality to mark all vtables of key functions as used withinChandler Carruth
a translation unit to the ActOnEndOfTranslationUnit function instead of doing it at the start of DefineUsedVTables. The latter is now called *recursively* during template instantiation, which causes an absolutely insane number of walks of every record decl in the translation unit. After this patch, an extremely template instantiation heavy test case's compile time drops by 10x, and we see between 15% and 20% improvement in average compile times across a project. This is just recovering a regression, it doesn't make anything faster than it was several weeks ago. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121644 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-25Tie DefineVTablesUsed() in with recursive function instantiation so that we emitNick Lewycky
a useful template instantiation stack. Fixes PR8640. This also causes a slight change to where the "instantianted from" note shows up in truly esoteric cases (see the change to test/SemaCXX/destructor.cpp), but that isn't directly the fault of this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120135 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-18Refactoring of Diagnostic class.Argyrios Kyrtzidis
-Move the stuff of Diagnostic related to creating/querying diagnostic IDs into a new DiagnosticIDs class. -DiagnosticIDs can be shared among multiple Diagnostics for multiple translation units. -The rest of the state in Diagnostic object is considered related and tied to one translation unit. -Have Diagnostic point to the SourceManager that is related with.

2010-10-13Fix a silly bug in the suppression of non-error diagnostics in aDouglas Gregor

2010-10-12Introduce support for emitting diagnostics (warnings + their notes)Douglas Gregor
that are suppressed during template argument deduction. This change queues diagnostics computed during template argument deduction. Then, if the resulting function template specialization or partial specialization is chosen by overload resolution or partial ordering (respectively), we will emit the queued diagnostics at that point. This addresses most of PR6784. However, the check for unnamed/local template arguments (which existed before this change) is still only skin-deep, and needs to be extended to look deeper into types. It must be improved to finish PR6784. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116373 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-13Implement caching of code-completion results for macro definitionsDouglas Gregor
when the CXTranslationUnit_CacheCompletionResults option is given to clang_parseTranslationUnit(). Essentially, we compute code-completion results for macro definitions after we have parsed the file, then store an ASTContext-agnostic version of those results (completion string, cursor kind, priority, and active contexts) in the ASTUnit. When performing code completion in that ASTUnit, we splice the macro definition results into the results provided by the actual code-completion (which has had macros turned off) before libclang gets those results. We use completion context information to only splice in those results that make sense for that context. With a completion involving all of the macros from Cocoa.h and a few other system libraries (totally ~8500 macro definitions) living in a precompiled header, we get about a 9% performance improvement from code completion, since we no longer have to deserialize all of the macro definitions from the precompiled header. Note that macro definitions are merely the canary; the cache is designed to also support other top-level declarations, which should be a bigger performance win. That optimization will be next. Note also that there is no mechanism for determining when to throw away the cache and recompute its contents. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111051 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-11Speculatively revert r110610 " Make ObjCInterfaceDecl redeclarable,Douglas Gregor

2010-08-09- Make ObjCInterfaceDecl redeclarable, and create separate decl nodes for ↵Sebastian Redl
forward declarations and the definition. - Eagerly create ObjCInterfaceTypes for declarations. - The two above changes lead to a 0.5% increase in memory use and no speed regression when parsing Cocoa.h. On the other hand, now chained PCH works when there's a forward declaration in one PCH and the interface definition in another. - Add HandleInterestingDecl to ASTConsumer. PCHReader passes the "interesting" decls it finds to this function instead of HandleTopLevelDecl. The default implementation forwards to HandleTopLevelDecl, but ASTUnit's handler for example ignores them. This fixes a potential crash when lazy loading of PCH data would cause ASTUnit's "top level" declaration collection to change while being iterated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110610 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-07Store inheritance paths after CastExprs instead of inside them.John McCall
This takes some trickery since CastExpr has subclasses (and indeed, is abstract). Also, smoosh the CastKind into the bitfield from Expr. Drops two words of storage from Expr in the common case of expressions which don't need inheritance paths. Avoids a separate allocation and another word of overhead in cases needing inheritance paths. Also has the advantage of not leaking memory, since destructors for AST nodes are never run. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110507 91177308-0d34-0410-b5e6-96231b3b80d8
