2010-02-16When emitting complete destructors for classes with virtual bases, computeJohn McCall
the offset to the virtual bases statically inside of relying on the virtual base offsets in the object's vtable(s). This is both more efficient and sound against the destructor's manipulation of the vtables. Also extract a few helper routines. Oh and we seem to pass all tests with an optimized clang now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96327 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-15Cope with anonymous tags defined within declarators by structurallyDouglas Gregor
comparing their types under the assumption that they are equivalent, rather than importing the types and then checking for compatibility. A few minor tweaks here: - Teach structural matching to handle compatibility between function types with prototypes and those without prototypes. - Teach structural matching that an incomplete record decl is the same as any other record decl with the same name. - Keep track of pairs of declarations that we have already checked (but failed to find as structurally matching), so we don't emit diagnostics repeatedly. - When importing a typedef of an anonymous tag, be sure to link the imported tag type to its typedef. With these changes, we survive a repeated import of <stdlib.h> and <stdio.h>. Alas, the ASTNodeImporter is getting a little grotty. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96298 91177308-0d34-0410-b5e6-96231b3b80d8

those declarations that we know will work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96280 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-15Reimplement the structural-equality checks used to determine whetherDouglas Gregor
two types in different AST contexts are equivalent. Rather than transforming the type from one context into the other context, we perform a deep structural comparison of the types. This change addresses a serious problem with recursive data types like struct ListNode { int value; struct ListNode *Next; } xList; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96278 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-14Change LLVMConventionsChecker to accept an entire translation unit insteadTed Kremenek
of operating on each code decl. This exposes two flaws in AnalysisConsumer that should eventually be fixed: (1) It is not possible to associate multiple "actions" with a single command line argument. This will require the notion of an "analysis" group, and possibly tablegen support. (although eventually we want to support dynamically loading analyses as well) (2) AnalysisConsumer may not actually be scanning the declarations in namespaces. We'll experiment first in LLVMConventionsChecker before changing the behavior in AnalysisConsumer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96183 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-14Add new static analyzer for checking LLVM coding conventions: ↵Ted Kremenek
-analyzer-check-llvm-conventions Currently these checks are intended to be largely syntactical, but may get more sophisticated over time. As an initial foray into this brave new world, emit a static analyzer warning when binding a temporary 'std::string' to an 'llvm::StringRef' where the lifetime of the 'std::string' does not outlive the 'llvm::StringRef'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96147 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-14Two changes to AnalysisConsumer::HandleTopLevelSingleDecl():Ted Kremenek
(1) Since CXXMethodDecl subclasses FunctionDecl (and CXXDestructorDecl and CXXConversion subclass CXXMethodDecl), refactor switch statement to handle them all in one spot. (2) Use 'DeclarationName::getAsString()' to handle all functions that don't have simple identifiers (fixing a null dereference when scanning for specific functions). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96146 91177308-0d34-0410-b5e6-96231b3b80d8
