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

2009-07-02Add 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

2009-06-30Key decisions about 'bool' vs '_Bool' to be based on a new flag in langoptions.Chris Lattner
This is simple enough, but then I thought it would be nice to make PrintingPolicy get a LangOptions so that various things can key off "bool" and "C++" independently. This spiraled out of control. There are many fixme's, but I think things are slightly better than they were before. One thing that can be improved: CFG should probably have an ASTContext pointer in it, which would simplify its clients. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74493 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-26Introduce a new concept to the static analyzer: SValuator.Ted Kremenek
GRTransferFuncs had the conflated role of both constructing SVals (symbolic expressions) as well as handling checker-specific logic. Now SValuator has the role of constructing SVals from expressions and GRTransferFuncs just handles checker-specific logic. The motivation is by separating these two concepts we will be able to much more easily create richer constraint-generating logic without coupling it to the main checker transfer function logic. We now have one implementation of SValuator: SimpleSValuator. SimpleSValuator is essentially the SVal-related logic that was in GRSimpleVals (which is removed in this patch). This includes the logic for EvalBinOp, EvalCast, etc. Because SValuator has a narrower role than the old GRTransferFuncs, the interfaces are much simpler, and so is the implementation of SimpleSValuator compared to GRSimpleVals. I also did a line-by-line review of SVal-related logic in GRSimpleVals and cleaned it up while moving it over to SimpleSValuator. As a consequence of removing GRSimpleVals, there is no longer a '-checker-simple' option. The '-checker-cfref' did everything that option did but also ran the retain/release checker. Of course a user may not always wish to run the retain/release checker, nor do we wish core analysis logic buried in the checker-specific logic. The next step is to refactor the logic in CFRefCount.cpp to separate out these pieces into the core analysis engine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74229 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-25Introduce the ResolveLocationInAST function which takes an ASTContext and a ↵Argyrios Kyrtzidis
SourceLocation and it resolves it into a <Decl*, Stmt*> pair. Decl* is the declaration associated with this source location and Stmt* is the statement/expression that the location points to. If the location does not point to a statement node, Stmt* is null. ResolveLocationInAST (along with converting a file:line:column triplet to a SourceLocation) will be useful for an IDE client and for clang's test suite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74197 91177308-0d34-0410-b5e6-96231b3b80d8
