- move DeclSpec &c into the Sema library - move ParseAST into the Parse library Reflect this change in a thousand different includes. Reflect this change in the link orders. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111667 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-13Rework Sema code completion interface.Daniel Dunbar
- Provide Sema in callbacks, instead of requiring it in constructor. This eliminates the need for a factory function. Clients now just pass the object to consume the results in directly. - CodeCompleteConsumer is cheap to construct, so building it whenever we are doing code completion is reasonable. Doug, please review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@87099 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-21Refactor and simplify the CodeCompleteConsumer, so that all of theDouglas Gregor
real work is performed within Sema. Addresses Chris's comments, but still retains the heavyweight list-of-multimaps data structure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82459 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-17Initial implementation of a code-completion interface in Clang. InDouglas Gregor
essence, code completion is triggered by a magic "code completion" token produced by the lexer [*], which the parser recognizes at certain points in the grammar. The parser then calls into the Action object with the appropriate CodeCompletionXXX action. Sema implements the CodeCompletionXXX callbacks by performing minimal translation, then forwarding them to a CodeCompletionConsumer subclass, which uses the results of semantic analysis to provide code-completion results. At present, only a single, "printing" code completion consumer is available, for regression testing and debugging. However, the design is meant to permit other code-completion consumers. This initial commit contains two code-completion actions: one for member access, e.g., "x." or "p->", and one for nested-name-specifiers, e.g., "std::". More code-completion actions will follow, along with improved gathering of code-completion results for the various contexts. [*] In the current -code-completion-dump testing/debugging mode, the file is truncated at the completion point and EOF is translated into "code completion". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82166 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-21Lazy deserialization of the declaration chains associated withDouglas Gregor
identifiers from a precompiled header. This patch changes the primary name lookup method for entities within a precompiled header. Previously, we would load all of the names of declarations at translation unit scope into a large DenseMap (inside the TranslationUnitDecl's DeclContext), and then perform a special "last resort" lookup into this DeclContext when we knew there was a PCH file (see Sema::LookupName). Now, when we see an identifier named for the first time, we load all of the declarations with that name that are visible from the translation unit into the IdentifierInfo's chain of declarations. Thus, the explicit "look into the translation unit's DeclContext" code is gone, and Sema effectively uses the same IdentifierInfo-based name lookup mechanism whether we are using a PCH file or not. This approach should help PCH scale with the size of the input program rather than the size of the PCH file. The "Hello, World!" application with Carbon.h as a PCH file now loads 20% of the identifiers in the PCH file rather than 85% of the identifiers. 90% of the 20% of identifiers loaded are actually loaded when we deserialize the preprocessor state. The next step is to make the preprocessor load macros lazily, which should drastically reduce the number of types, declarations, and identifiers loaded for "Hello, World". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69737 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-20Introduce the notion of a SemaConsumer, which is an ASTConsumer thatDouglas Gregor
also gets access to the Sema object performing semantic analysis. This will be used by the PCH writer to serialize Sema state. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69595 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-14When building a PCH file, don't perform end-of-translation-unitDouglas Gregor
wrap-up (e.g., turning tentative definitions into definitions). Also, very that, when we actually use the PCH file, we get the ride code generation for tentative definitions and definitions that show up in the PCH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69043 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-14When writing a PCH file, keep track of all of the non-static,Douglas Gregor
non-inline external definitions (and tentative definitions) that are found at the top level. The corresponding declarations are stored in a record in the PCH file, so that they can be provided to the ASTConsumer (via HandleTopLevelDecl) when the PCH file is read. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69005 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-29Push DeclGroup much farther throughout the compiler. Now the variousChris Lattner
productions (except the already broken ObjC cases like @class X,Y;) in the parser that can produce more than one Decl return a DeclGroup instead of a Decl, etc. This allows elimination of the Decl::NextDeclarator field, and exposes various clients that should look at all decls in a group, but which were only looking at one (such as the dumper, printer, etc). These have been fixed. Still TODO: 1) there are some FIXME's in the code about potentially using DeclGroup for better location info. 2) ParseObjCAtDirectives should return a DeclGroup due to @class etc. 3) I'm not sure what is going on with StmtIterator.cpp, or if it can be radically simplified now. 4) I put a truly horrible hack in ParseTemplate.cpp. I plan to bring up #3/4 on the mailing list, but don't plan to tackle #1/2 in the short term. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68002 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-28Introduce a new OpaquePtr<N> struct type, which is a simple POD wrapper for aChris Lattner
pointer. Its purpose in life is to be a glorified void*, but which does not implicitly convert to void* or other OpaquePtr's with a different UID. Introduce Action::DeclPtrTy which is a typedef for OpaquePtr<0>. Change the entire parser/sema interface to use DeclPtrTy instead of DeclTy*. This makes the C++ compiler enforce that these aren't convertible to other opaque types. We should also convert ExprTy, StmtTy, TypeTy, AttrTy, BaseTy, etc, but I don't plan to do that in the short term. The one outstanding known problem with this patch is that we lose the bitmangling optimization where ActionResult<DeclPtrTy> doesn't know how to bitmangle the success bit into the low bit of DeclPtrTy. I will rectify this with a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67952 91177308-0d34-0410-b5e6-96231b3b80d8
