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

2009-07-17Replace Type::getAsReferenceType() with Type::getAs<ReferenceType>().Ted Kremenek

2009-07-16Add member template 'Type::getAs<T>', which converts a Type* to a respective T*.Ted Kremenek
This method is intended to eventually replace the individual Type::getAsXXXType<> methods. The motivation behind this change is twofold: 1) Reduce redundant implementations of Type::getAsXXXType() methods. Most of them are basically copy-and-paste. 2) By centralizing the implementation of the getAs<Type> logic we can more smoothly move over to Doug Gregor's proposed canonical type smart pointer scheme. Along with this patch: a) Removed 'Type::getAsPointerType()'; now clients use getAs<PointerType>. b) Removed 'Type::getAsBlockPointerTypE()'; now clients use getAs<BlockPointerType>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76098 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-30Preliminary parsing and ASTs for template-ids that refer to functionDouglas Gregor

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". Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74506 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

2009-06-11Once we have deduced the template arguments of a class templateDouglas Gregor
partial specialization, substitute those template arguments back into the template arguments of the class template partial specialization to see if the results still match the original template arguments.

2009-06-04When performing template argument deduction, ensure that multipleDouglas Gregor
deductions of the same template parameter are equivalent. This allows us to implement the is_same type trait (!). Also, move template argument deduction into its own file and update a few build systems with this change (grrrr). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72819 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-31Initial infrastructure for class template partial specialization. HereDouglas Gregor
we have the basics of declaring and storing class template partial specializations, matching class template partial specializations at instantiation time via (limited) template argument deduction, and using the class template partial specialization's pattern for instantiation. This patch is enough to make a simple is_pointer type trait work, but not much else. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72662 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-28When we parse a tag specifier, keep track of whether that tagDouglas Gregor
specifier resulted in the creation of a new TagDecl node, which happens either when the tag specifier was a definition or when the tag specifier was the first declaration of that tag type. This information has several uses, the first of which is implemented in this commit: 1) In C++, one is not allowed to define tag types within a type specifier (e.g., static_cast<struct S { int x; } *>(0) is ill-formed) or within the result or parameter types of a function. We now diagnose this. 2) We can extend DeclGroups to contain information about any tags that are declared/defined within the declaration specifiers of a variable, e.g., struct Point { int x, y, z; } p; This will help improve AST printing and template instantiation, among other things. 3) For C99, we can keep track of whether a tag type is defined within the type of a parameter, to properly cope with cases like, e.g., int bar(struct T2 { int x; } y) { struct T2 z; } We can also do similar things wherever there is a type specifier, e.g., to keep track of where the definition of S occurs in this legal C99 code: (struct S { int x, y; } *)0 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72555 91177308-0d34-0410-b5e6-96231b3b80d8
