2009-07-29Remove 'StoreManager::OldCastRegion()', TypedViewRegion (which onlyTed Kremenek
OldCastRegion used), and the associated command line option '-analyzer-store=old-basic-cast'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77509 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-27(1) Enable PlistDiagnostics to take an option "PathDiagnosticClientFactory"Ted Kremenek
object that it can use to forward PathDiagnostics for further processing. Along with this feature, the PlistDiagnostics object logs which files are created by the forwarding of the PathDiagnostics. (2) Create a new PathDiagnosticClientFactory object for HTMLDiagnostics, allowing other PathDiagnosticClients to forward PathDiagnostics through an opaque interface. (3) Create a "plist-html" diagnostics option in AnalysisConsumer to allow the logging of HTML files created in a hybrid Plist+HTML diagnostic client. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77264 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-15Implement the ObjC pseudo built-in types as clang "BuiltinType's". I say ↵Steve Naroff
pseudo built-in types, since Sema still injects a typedef for recognition (i.e. they aren't truly built-ins from a parser perspective). This removes the static data/methods on ObjCObjectPointerType while preserving the nice API (no need to fiddle with ASTContext:-). This patch also adds Type::isObjCBuiltinType(). This should be the last fairly large patch related to recrafting the ObjC type system. The follow-on patches should be fairly small. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75808 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-10Switch BasicStoreManager to use the new CastRegion implementation by default,Ted Kremenek

2009-07-07Make ASTContext explicitly keep track of the declaration for the CDouglas Gregor
FILE type, rather than using name lookup to find FILE within the translation unit. Within precompiled headers, FILE is treated as yet another "special type" (like __builtin_va_list). This change should provide a performance improvement (not verified), since the lookup into the translation unit declaration forces the (otherwise unneeded) construction of a large hash table. More importantly, with precompiled headers, the construction of that table requires deserializing most of the top-level declarations from the precompiled header, which are then unused. Fixes PR 4509. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74911 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-07Introduce the notion of "Relocatable" precompiled headers, which are builtDouglas Gregor
with a particular system root directory and can be used with a different system root directory when the headers it depends on have been installed. Relocatable precompiled headers rewrite the file names of the headers used when generating the PCH file into the corresponding file names of the headers available when using the PCH file.

of a top-level declaration loads another top-level declaration of the same name whose type depends on the first declaration having been completed.

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

2009-06-26Introduce 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

representation. Add a type (ObjCObjectPointerType) and remove a type (ObjCQualifiedIdType). This large/tedious patch is just a first step. Next step is to remove ObjCQualifiedInterfaceType.

2009-06-14Update LLVM.Douglas Gregor
Implement support for C++ Substitution Failure Is Not An Error (SFINAE), which says that errors that occur during template argument deduction do *not* produce diagnostics and do not necessarily make a program ill-formed. Instead, template argument deduction silently fails. This is currently implemented for template argument deduction during matching of class template partial specializations, although the mechanism will also apply to template argument deduction for function templates. The scheme is simple: - If we are in a template argument deduction context, any diagnostic that is considered a SFINAE error (or warning) will be suppressed. The error will be propagated up the call stack via the normal means. - By default, all warnings and errors are SFINAE errors. Add the NoSFINAE class to a diagnostic in the .td file to make it a hard error (e.g., for access-control violations). Note that, to make this fully work, every place in Sema that emits an error *and then immediately recovers* will need to check Sema::isSFINAEContext() to determine whether it must immediately return an error rather than recovering. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73332 91177308-0d34-0410-b5e6-96231b3b80d8
