* Rework when and how vtables are emitted, by tracking where vtables areDouglas Gregor2010-05-131-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "used" (e.g., we will refer to the vtable in the generated code) and when they are defined (i.e., because we've seen the key function definition). Previously, we were effectively tracking "potential definitions" rather than uses, so we were a bit too eager about emitting vtables for classes without key functions. The new scheme: - For every use of a vtable, Sema calls MarkVTableUsed() to indicate the use. For example, this occurs when calling a virtual member function of the class, defining a constructor of that class type, dynamic_cast'ing from that type to a derived class, casting to/through a virtual base class, etc. - For every definition of a vtable, Sema calls MarkVTableUsed() to indicate the definition. This happens at the end of the translation unit for classes whose key function has been defined (so we can delay computation of the key function; see PR6564), and will also occur with explicit template instantiation definitions. - For every vtable defined/used, we mark all of the virtual member functions of that vtable as defined/used, unless we know that the key function is in another translation unit. This instantiates virtual member functions when needed. - At the end of the translation unit, Sema tells CodeGen (via the ASTConsumer) which vtables must be defined (CodeGen will define them) and which may be used (for which CodeGen will define the vtables lazily). From a language perspective, both the old and the new schemes are permissible: we're allowed to instantiate virtual member functions whenever we want per the standard. However, all other C++ compilers were more lazy than we were, and our eagerness was both a performance issue (we instantiated too much) and a portability problem (we broke Boost test cases, which now pass). Notes: (1) There's a ton of churn in the tests, because the order in which vtables get emitted to IR has changed. I've tried to isolate some of the larger tests from these issues. (2) Some diagnostics related to implicitly-instantiated/implicitly-defined virtual member functions have moved to the point of first use/definition. It's better this way. (3) I could use a review of the places where we MarkVTableUsed, to see if I missed any place where the language effectively requires a vtable. Fixes PR7114 and PR6564. llvm-svn: 103718
* Revert changes r97693, r97700, and r97718.John McCall2010-03-041-9/+4

* Explictly track tentative definitions within Sema, then hand thoseDouglas Gregor2009-04-211-0/+7
| | | | | | | | | | | | | | | tentative definitions off to the ASTConsumer at the end of the translation unit. Eliminate CodeGen's internal tracking of tentative definitions, and instead hook into ASTConsumer::CompleteTentativeDefinition. Also, tweak the definition-deferal logic for C++, where there are no tentative definitions. Fixes <rdar://problem/6808352>, and will make it much easier for precompiled headers to cope with tentative definitions in the future. llvm-svn: 69681
* Push DeclGroup much farther throughout the compiler. Now the variousChris Lattner2009-03-291-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 68002

* Remove ScopedDecl, collapsing all of its functionality into Decl, soDouglas Gregor2009-01-201-2/+2
| | | | | | | | | | | | | | | | that every declaration lives inside a DeclContext. Moved several things that don't have names but were ScopedDecls (and, therefore, NamedDecls) to inherit from Decl rather than NamedDecl, including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't store empty DeclarationNames for these things, nor do we try to insert them into DeclContext's lookup structure. The serialization tests are temporarily disabled. We'll re-enable them once we've sorted out the remaining ownership/serialiazation issues between DeclContexts and TranslationUnion, DeclGroups, etc. llvm-svn: 62562

* Clean up CodeGenModule interface.Daniel Dunbar2008-08-151-54/+6
| | | | | | | | | | | - Add CodeGenModule::EmitTopLevelDecl which uses switch on kind instead of ugly & slow dyn_cast chains. - Drop some simple forwarding methods into the ObjC runtime. - Privatize appropriate methods. llvm-svn: 54827

* Add LangOptions::NeXTRuntime.Daniel Dunbar2008-08-111-2/+1
| | | | | | | | | - Wired to -fnext-runtime and -fgnu-runtime options. - Defaults to GNU, no autoselection for NeXT. Emit NeXT OBJC_IMAGE_INFO marker. llvm-svn: 54651
* More #include cleaningDaniel Dunbar2008-08-111-3/+0
| | | | | | | | | | | - Kill unnecessary #includes in .cpp files. This is an automatic sweep so some things removed are actually used, but happen to be included by a previous header. I tried to get rid of the obvious examples and this was the easiest way to trim the #includes in one fell swoop. - We now return to regularly scheduled development. llvm-svn: 54632

* ParseAST now conditionally deletes the passed ASTConsumer.Ted Kremenek2008-08-071-8/+11
| | | | | | | | | | ModuleBuilder now performs llvmgen in HandleTranslationUnit. This patch follows from the discussion on the following thread on cfe-commits: http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20080804/006849.html llvm-svn: 54486

| | | | | | ASTConsumer layers on top of LLVMCodeGen (another existing ASTConsumer) to emit bitcode files to disk. This layering takes this logic out of clang.cpp and puts it directly into the ASTConsumer interface. The benefit is that now --emit-llvm works with both serialized ASTs and regular source files. llvm-svn: 54364
* Rework codegen emission of globalsDaniel Dunbar2008-07-291-3/+3
| | | | | | | | | | | | | | | | | | | | - No (intended) functionality change. - Primary purpose is to clearly separate (lazy) construction of globals that are a forward declaration or tentative definition from those that are the final definition. - Lazy construction is now encapsulated in GetAddrOf{Function,GlobalVar} while final definitions are constructed in EmitGlobal{Function,Var}Definition. - External interface for dealing with globals is now limited to EmitGlobal and GetAddrOf{Function,GlobalVar}. - Also updated helper functions dealing with statics, annotations, and ctors to be private. llvm-svn: 54179
* Fix codegen of chained declarationsDaniel Dunbar2008-07-291-3/+8

* Remove FileVarDecl and BlockVarDecl. They are replaced by ↵Steve Naroff2008-04-151-2/+3
| | | | | | | | VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl(). This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it). llvm-svn: 49748

lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. llvm-svn: 48402
