2009-07-22Add warning for falling off the end of a function that should return aMike Stump
value. This is on by default, and controlled by -Wreturn-type (-Wmost -Wall). I believe there should be very few false positives, though the most interesting case would be: int() { bar(); } when bar does: bar() { while (1) ; } Here, we assume functions return, unless they are marked with the noreturn attribute. I can envision a fixit note for functions that never return normally that don't have a noreturn attribute to add a noreturn attribute. If anyone spots other false positives, let me know! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76821 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Implement support for out-of-line definitions of the class members of classDouglas Gregor
templates, e.g., template<typename T> struct Outer { struct Inner; }; template<typename T> struct Outer<T>::Inner { // ... }; Implementing this feature required some extensions to ActOnTag, which now takes a set of template parameter lists, and is the precursor to removing the ActOnClassTemplate function from the parser Action interface. The reason for this approach is simple: the parser cannot tell the difference between a class template definition and the definition of a member of a class template; both have template parameter lists, and semantic analysis determines what that template parameter list means. There is still some cleanup to do with ActOnTag and ActOnClassTemplate. This commit provides the basic functionality we need, however. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76820 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-17Per offline discussion with Steve Naroff, add back Type::getAsXXXType() methodsTed Kremenek
until Doug Gregor's Type smart pointer code lands (or more discussion occurs). These methods just call the new Type::getAs<XXX> methods, so we still have reduced implementation redundancy. Having explicit getAsXXXType() methods makes it easier to set breakpoints in the debugger. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76193 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-14Add a "TypeSpecStartLoc" to FieldDecl. Patch contributed by Enea Zaffanella.Steve Naroff
Note: One day, it might be useful to consider adding this info to DeclGroup (as the comments in FunctionDecl/VarDecl suggest). For now, I think this works fine. I considered moving this to ValueDecl (a common ancestor of FunctionDecl/VarDecl/FieldDecl), however this would add overhead to EnumConstantDecl (which would burn memory and isn't necessary). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75635 91177308-0d34-0410-b5e6-96231b3b80d8

- Declaration context of ParmVarDecls (that we got from the Declarator) was not their containing function. - C++ out-of-line method definitions didn't get an access specifier. Both were exposed by a crash when emitting a C++ method to a PCH file (assert at Decl::CheckAccessDeclContext()). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75597 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-10This patch includes a conceptually simple, but very intrusive/pervasive change. Steve Naroff
The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches. This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic. By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time. Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75314 91177308-0d34-0410-b5e6-96231b3b80d8

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

2009-06-30Remove the ASTContext parameter from the attribute-related methods of Decl.Argyrios Kyrtzidis
The implementations of these methods can Use Decl::getASTContext() to get the ASTContext. This commit touches a lot of files since call sites for these methods are everywhere. I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74501 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-25Improved semantic analysis and AST respresentation for functionDouglas Gregor
templates. For example, this now type-checks (but does not instantiate the body of deref<int>): template<typename T> T& deref(T* t) { return *t; } void test(int *ip) { int &ir = deref(ip); } Specific changes/additions: * Template argument deduction from a call to a function template. * Instantiation of a function template specializations (just the declarations) from the template arguments deduced from a call. * FunctionTemplateDecls are stored directly in declaration contexts and found via name lookup (all forms), rather than finding the FunctionDecl and then realizing it is a template. This is responsible for most of the churn, since some of the core declaration matching and lookup code assumes that all functions are FunctionDecls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74213 91177308-0d34-0410-b5e6-96231b3b80d8
