2012-03-05Fix a small difference in sema and codegen views of what needs to be output.Rafael Espindola
In the included testcase, soma thinks that we already have a definition after we see the out of line decl. Codegen puts it in a deferred list, to be output if a use is seen. This would break when we saw an explicit template instantiation definition, since codegen would not be notified. This patch adds a method to the consumer interface so that soma can notify codegen that this decl is now required. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152024 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-02Extend the ASTContext constructor to delay the initialization ofDouglas Gregor
builtin types (When requested). This is another step toward making ASTUnit build the ASTContext as needed when loading an AST file, rather than doing so after the fact. No actual functionality change (yet). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138985 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-06Modify some deleted function methods to better reflect reality:Sean Hunt
- New isDefined() function checks for deletedness - isThisDeclarationADefinition checks for deletedness - New doesThisDeclarationHaveABody() does what isThisDeclarationADefinition() used to do - The IsDeleted bit is not propagated across redeclarations - isDeleted() now checks the canoncial declaration - New isDeletedAsWritten() does what it says on the tin. - isUserProvided() now correct (thanks Richard!) This fixes the bug that we weren't catching void foo() = delete; void foo() {} as being a redefinition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131013 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-15Move CodeGenOptions.h *back* into Frontend. This should have been done when theChandler Carruth

2010-05-13Rework when and how vtables are emitted, by tracking where vtables areDouglas Gregor
"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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103718 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-21Explictly track tentative definitions within Sema, then hand thoseDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69681 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

2009-01-20Remove ScopedDecl, collapsing all of its functionality into Decl, soDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62562 91177308-0d34-0410-b5e6-96231b3b80d8

ASTConsumer layers on top of LLVMCodeGen (another existing ASTConsumer) to emit bitcode files to disk.

2008-07-29Rework codegen emission of globalsDaniel Dunbar
- 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54179 91177308-0d34-0410-b5e6-96231b3b80d8
