Ted Kremenek	4ba99bee2a	clang::Attr objects should be treated as AST nodes as well by ... the LLVMConventionsChecker. llvm-svn: 96202	2010-02-14 22:58:16 +00:00
Ted Kremenek	4853131459	Add LLVM conventions check that scans for AST elements (types, stmts, decls) ... that allocate heap memory. llvm-svn: 96184	2010-02-14 19:09:13 +00:00
Ted Kremenek	988805c81e	Change LLVMConventionsChecker to accept an entire translation unit instead ... 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. llvm-svn: 96183	2010-02-14 19:09:05 +00:00
Ted Kremenek	c968e5e9b9	For the StringRef check, also visit the children of DeclStmts. ... llvm-svn: 96181	2010-02-14 19:08:43 +00:00
Ted Kremenek	4806a833a7	Place type-checking static methods at type of file (where they will congregate). ... No functionality change. llvm-svn: 96180	2010-02-14 19:08:36 +00:00
Ted Kremenek	184b3383bf	Add new static analyzer for checking LLVM coding conventions: -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'. llvm-svn: 96147	2010-02-14 02:45:18 +00:00
