2009-10-13Improve diagnostics when the parser encounters a declarator with anDouglas Gregor
unknown type name, e.g., foo::bar x; when "bar" does not refer to a type in "foo". With this change, the parser now calls into the action to perform diagnostics and can try to recover by substituting in an appropriate type. For example, this allows us to easily diagnose some missing "typename" specifiers, which we now do: test/SemaCXX/unknown-type-name.cpp:29:1: error: missing 'typename' prior to dependent type name 'A<T>::type' A<T>::type A<T>::f() { return type(); } ^~~~~~~~~~ typename Fixes PR3990. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84053 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13Unify our diagnostic printing for errors of the form, "we didn't likeDouglas Gregor
what we found when we looked into <blah>", where <blah> is a DeclContext*. We can now format DeclContext*'s in nice ways, e.g., "namespace N", "the global namespace", "'class Foo'". This is part of PR3990, but we're not quite there yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84028 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-02Rewrite of our handling of name lookup in C++ member access expressions, e.g.,Douglas Gregor
x->Base::f We no longer try to "enter" the context of the type that "x" points to. Instead, we drag that object type through the parser and pass it into the Sema routines that need to know how to perform lookup within member access expressions. We now implement most of the crazy name lookup rules in C++ [basic.lookup.classref] for non-templated code, including performing lookup both in the context of the type referred to by the member access and in the scope of the member access itself and then detecting ambiguities when the two lookups collide (p1 and p4; p3 and p7 are still TODO). This change also corrects our handling of name lookup within template arguments of template-ids inside the nested-name-specifier (p6; we used to look into the scope of the object expression for them) and fixes PR4703. I have disabled some tests that involve member access expressions where the object expression has dependent type, because we don't yet have the ability to describe dependent nested-name-specifiers starting with an identifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80843 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-21Fix a crash that occurs in this C++ case:Argyrios Kyrtzidis
struct foo { static bool value; }; bool (foo::value); // crash because of parens git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76538 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-26Improve error recovery in C++: when we hit 'implicit int' cases in C++,Chris Lattner
these are usually because the parser was thoroughly confused. In addition to typing the value being declared as an int and hoping for the best, we mark the value as invalid so we don't get chains of errors when it is used downstream. In C, implicit int actually is valid, so typing the thing as int is good and marking it invalid is bad. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74266 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-26fix PR4452, a crash on invalid. The error recovery is still terrible in ↵Chris Lattner
this case but at least we don't crash :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74264 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-14Make the implicit-int handling error recovery stuff handle C++Chris Lattner
nested name specifiers. Now we emit stuff like: t.cpp:8:13: error: unknown type name 'X' static foo::X P; ~~~~ ^ instead of: t.cpp:8:16: error: invalid token after top level declarator static foo::X P; ^ This is inspired by a really awful error message I got from g++ when I misspelt diag::kind as diag::Kind. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69086 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-12Fix some C++ error recovery problems in init declarator parsingChris Lattner
that I noticed working on other things. Instead of emitting: t2.cc:1:8: error: use of undeclared identifier 'g' int x(*g); ^ t2.cc:1:10: error: expected ')' int x(*g); ^ t2.cc:1:6: note: to match this '(' int x(*g); ^ We now only emit: t2.cc:1:7: warning: type specifier missing, defaults to 'int' int x(*g); ^ Note that the example in SemaCXX/nested-name-spec.cpp:f4 is still not great, we now produce both of: void f4(undef::C); // expected-error {{use of undeclared identifier 'undef'}} \ expected-error {{variable has incomplete type 'void'}} The second diagnostic should be silenced by something getting marked invalid. I don't plan to fix this though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68919 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-25Improve handling of base initializers. We now parse initializers in out of ↵Anders Carlsson
line decls, such as: class C { C() { } int a; }; C::C() : a(10) { } We also diagnose when initializers are used on declarations that aren't constructors: t.cpp:1:10: error: only constructors take base initializers void f() : a(10) { } ^ Doug and/or Sebastian: I'd appreciate a review, especially the nested-name-spec test results (from the looks of it we now match gcc in that test.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67672 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-23Template instantiation for the declarations of member functions withinDouglas Gregor
a class template. At present, we can only instantiation normal methods, but not constructors, destructors, or conversion operators. As ever, this contains a bit of refactoring in Sema's type-checking. In particular: - Split ActOnFunctionDeclarator into ActOnFunctionDeclarator (handling the declarator itself) and CheckFunctionDeclaration (checking for the the function declaration), the latter of which is also used by template instantiation. - We were performing the adjustment of function parameter types in three places; collect those into a single new routine. - When the type of a parameter is adjusted, allocate an OriginalParmVarDecl to keep track of the type as it was written. - Eliminate a redundant check for out-of-line declarations of member functions; hide more C++-specific checks on function declarations behind if(getLangOptions().CPlusPlus). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67575 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-11Add basic, hackish support for instantiation of typedefs in a classDouglas Gregor
template. More importantly, start to sort out the issues regarding complete types and nested-name-specifiers, especially the question of: when do we instantiate a class template specialization that occurs to the left of a '::' in a nested-name-specifier? git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66662 91177308-0d34-0410-b5e6-96231b3b80d8
