2009-07-06Some changes to ASTLocation's methodsArgyrios Kyrtzidis
-Change hasStmt() to isStmt() -Add isDecl() -Add getSourceRange() git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74862 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-06Move the 'ResolveLocationInAST' function from the Frontend library to the ↵Argyrios Kyrtzidis
Index library. Also, cut down its comments; more comments will be added to ASTLocation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74860 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-06Rename 'ASTNode' -> 'ASTLocation'.Argyrios Kyrtzidis
ASTLocation is a much better name for its intended purpose which to represent a "point" into the AST. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74858 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-06NewCastRegion:Ted Kremenek
- Have test for 'CodeTextRegion' dominate other region tests. - Use 'getAsRecordType' instead of isa<RecordType> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74853 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-06Fix loop so that 'continue' statements actually cause the loop to iterate.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74852 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-06Move the new 'CastRegion' implementation from RegionStoreManager to StoreManagerTed Kremenek
(its superclass). This will allow us to experiment with using the new CastRegion with BasicStoreManager, and gradually phase out the old implementation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74851 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-06Fix a problem with false diagnostics when comparing distinct NULL pointer ↵Douglas Gregor
types, from David Majnemer git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74850 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-06Fix PR 4489, a crash in PCH loading that occurs when loading the nameDouglas Gregor
of a top-level declaration loads another top-level declaration of the same name whose type depends on the first declaration having been completed. This commit breaks the circular dependency by delaying loads of top-level declarations triggered by loading a name until we are no longer recursively loading types or declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74847 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-06Fix <rdar://problem/7033733>. The CF_RETURNS_RETAINED attribute should work ↵Ted Kremenek
if the return type on an Objective-C method is a CF type reference, not just an Objective-C object reference. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74841 91177308-0d34-0410-b5e6-96231b3b80d8

No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74812 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-05Fix for PR4502: add calculation of the integer conversion rank for Eli Friedman
wchar_t. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74808 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-05More tweaks to types for OpenBSD. Patch by Jonathan Gray.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74805 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-05Introduce the 'Index' library.Argyrios Kyrtzidis
Its purpose is to provide the basic infrastructure for cross-translation-unit analysis like indexing, refactoring, etc. Currently it is very "primitive" and with no type-names support. It can provide functionality like "show me all references of this function from these translation units". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74802 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-05Introduce the DeclReferenceMap class inside the AST library.Argyrios Kyrtzidis
DeclReferenceMap (similar to ParentMap) is a helper class for mapping Decls to the AST nodes that reference them. A client will initialize it by passing an ASTContext to its constructor and later use it to iterate over the references of a Decl. References are mapped and retrieved using the primary declaration (Decl::getPrimaryDecl()) of a particular Decl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74801 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-05Introduce the virtual method Decl::getPrimaryDecl().Argyrios Kyrtzidis
When a Decl subclass can have multiple re-declarations in the same declaration context (like FunctionDecl), getPrimaryDecl() will return a particular Decl that all of them will point to as the "primary" declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74800 91177308-0d34-0410-b5e6-96231b3b80d8

the index-test tool. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74798 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-05Introduce ASTNode class into the AST library.Argyrios Kyrtzidis
ASTNode is an immutable pair of a Decl and Stmt. If Stmt is not null, Decl should be its immediate parent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74797 91177308-0d34-0410-b5e6-96231b3b80d8

to deal with for AST pretty-printing/rewriting. Patch by Abramo Bagnara. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74752 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-03BasicStoreManager: Use SymbolManager::canSymbolicate() to determine if a ↵Ted Kremenek
variable can be symbolicated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74750 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-03Fix a horrible CFG bug reported in <rdar://problem/7027684>. The wrong successorTed Kremenek
block would get hooked up in some cases when processing empty compound statements. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74743 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-02Replace guarded calls in RegionStoreManager toTed Kremenek
ValueManager::getRegionValueSymbolVal() with unguarded calls to ValueManager::getRegionValueSymbolValOrUnknown(). This changes centralizes the decision of what values to symbolicate in SymbolManager rather than having it scatter in RegionStoreManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74730 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-02StoreManagers: Use 'hasGlobalsStorage()' and 'hasParametersStorage()' instead ofTed Kremenek
directly consulting if a VarDecl is an implicit or actual parameter, a global, etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74716 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-02Add a separate MemSpaceRegion for function/method arguments passed on the stack.Ted Kremenek
This will simplify the logic of StoreManagers that want to specially reason about the values of parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74715 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74709 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-02Add support for retrieving the Doxygen comment associated with a givenDouglas Gregor
declaration in the AST. The new ASTContext::getCommentForDecl function searches for a comment that is attached to the given declaration, and returns that comment, which may be composed of several comment blocks. Comments are always available in an AST. However, to avoid harming performance, we don't actually parse the comments. Rather, we keep the source ranges of all of the comments within a large, sorted vector, then lazily extract comments via a binary search in that vector only when needed (which never occurs in a "normal" compile). Comments are written to a precompiled header/AST file as a blob of source ranges. That blob is only lazily loaded when one requests a comment for a declaration (this never occurs in a "normal" compile). The indexer testbed now supports comment extraction. When the -point-at location points to a declaration with a Doxygen-style comment, the indexer testbed prints the associated comment block(s). See test/Index/comments.c for an example. Some notes: - We don't actually attempt to parse the comment blocks themselves, beyond identifying them as Doxygen comment blocks to associate them with a declaration. - We won't find comment blocks that aren't adjacent to the declaration, because we start our search based on the location of the declaration. - We don't go through the necessary hops to find, for example, whether some redeclaration of a declaration has comments when our current declaration does not. Similarly, we don't attempt to associate a \param Foo marker in a function body comment with the parameter named Foo (although that is certainly possible). - Verification of my "no performance impact" claims is still "to be done". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74704 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-01Add a FIXME to RegionStore, do some minor code cleanup, and get RegionStore toTed Kremenek
pass misc-ps.m. Currently RegionStore/BasicStore don't do any special reasoning about clang-style vectors, so we should return UnknownVal (in all cases) when accessing their values via an array. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74660 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-01Keep track of more information within the template instantiation stack, e.g.,Douglas Gregor
by distinguishing between substitution that occurs for template argument deduction vs. explicitly-specifiad template arguments. This is used both to improve diagnostics and to make sure we only provide SFINAE in those cases where SFINAE should apply. In addition, deal with the sticky issue where SFINAE only considers substitution of template arguments into the *type* of a function template; we need to issue hard errors beyond this point, as test/SemaTemplate/operator-template.cpp illustrates. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74651 91177308-0d34-0410-b5e6-96231b3b80d8
