2009-07-13Fix 5 issues from Chris's feedback on ↵Steve Naroff
http://llvm.org/viewvc/llvm-project?view=rev&revision=75314. Still more to come...just wanted to get the no-brainers out of the way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75477 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11Fix warning when compiling with optimizations:Ted Kremenek
warning: ‘OPT’ may be used uninitialized in this function Now OPT is initialized to NULL. I'm not certain if this is the correct fix; others please review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75321 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

2009-07-08Implement template argument deduction when taking the address of aDouglas Gregor
function template. Most of the change here is in factoring out the common bits used for template argument deduction from a function call and when taking the address of a function template. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75044 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-01Rework Sema::CheckConditionalOperands(). No functionality change.Steve Naroff
This was necessary to simplify some other changes I'm making (wrt ObjC type cleanups). The idea is to separate the constraint checks for block pointers, ObjC pointers, and C pointers (the previous code combined them into one clause). Note: This routine will be further simplified when I integrate the ObjC type cleanups (forthcoming). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74604 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30When explicit template arguments are provided for a function call,Douglas Gregor
substitute those template arguments into the function parameter types prior to template argument deduction. There's still a bit of work to do to make this work properly when only some of the template arguments are specified. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74576 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Preliminary parsing and ASTs for template-ids that refer to functionDouglas Gregor
templates, such as make<int&>. These template-ids are only barely functional for function calls; much more to come. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74563 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30When recursively instantiating function templates, keep track of theDouglas Gregor
instantiation stack so that we provide a full instantiation backtrace. Previously, we performed all of the instantiations implied by the recursion, but each looked like a "top-level" instantiation. The included test case tests the previous fix for the instantiation of DeclRefExprs. Note that the "instantiated from" diagnostics still don't tell us which template arguments we're instantiating with. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74540 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Refactor ActOnDeclarationNameExpr into a "parsing action" part and aDouglas Gregor
"semantic analysis" part. Use the "semantic analysis" part when performing template instantiation on a DeclRefExpr, rather than an ad hoc list of rules to construct DeclRefExprs from the instantiation. A test case for this change will come in with a large commit, which illustrates what I was actually trying to work on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74528 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-30De-ASTContext-ify DeclContext.Argyrios Kyrtzidis
Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating".

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

2009-06-26Implicit instantiation for function template specializations.Douglas Gregor
For a FunctionDecl that has been instantiated due to template argument deduction, we now store the primary template from which it was instantiated and the deduced template arguments. From this information, we can instantiate the body of the function template. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74232 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

2009-06-22Rework the way we track which declarations are "used" duringDouglas Gregor
compilation, and (hopefully) introduce RAII objects for changing the "potentially evaluated" state at all of the necessary places within Sema and Parser. Other changes: - Set the unevaluated/potentially-evaluated context appropriately during template instantiation. - We now recognize three different states while parsing or instantiating expressions: unevaluated, potentially evaluated, and potentially potentially evaluated (for C++'s typeid). - When we're in a potentially potentially-evaluated context, queue up MarkDeclarationReferenced calls in a stack. For C++ typeid expressions that are potentially evaluated, we will play back these MarkDeclarationReferenced calls when we exit the corresponding potentially potentially-evaluated context. - Non-type template arguments are now parsed as constant expressions, so they are not potentially-evaluated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73899 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-19Keep track of when declarations are "used" according to C andDouglas Gregor

2009-06-17First step toward fixing <rdar://problem/6613046> refactor clang objc type ↵Steve Naroff
