t.c:3:8: warning: extra tokens at end of #endif directive #endif foo ^ // Don't do this in strict-C89 mode because bcpl comments aren't valid there, and it is too much trouble to analyze whether C block comments are safe. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69024 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-14Audit __private_extern__ handling.Daniel Dunbar
- Exposed quite a few Sema issues and a CodeGen crash. - See FIXMEs in test case, and in SemaDecl.cpp (PR3983). I'm skeptical that __private_extern__ should actually be a storage class value. I think that __private_extern__ basically amounts to extern A __attribute__((visibility("hidden"))) and would be better off handled (a) as that, or (b) with an extra bit in the VarDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69020 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-14When writing a PCH file, keep track of all of the non-static,Douglas Gregor
non-inline external definitions (and tentative definitions) that are found at the top level. The corresponding declarations are stored in a record in the PCH file, so that they can be provided to the ASTConsumer (via HandleTopLevelDecl) when the PCH file is read. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69005 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-13Change diagnostic as a result of researching <rdar://problem/6779809> ↵Steve Naroff
missing interface name in "error: cannot declare variable inside a class, protocol or category ''. Since ObjC 2.0 class "extensions" have a null name, the diagnostic above is actually "correct". Nevertheless, it is confusing. Decided to remove the name entirely (from my perspective, it didn't add any value). Also simplified the text of the diagnostic a bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68967 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

2009-04-12Diagnose invalid uses of tagged types with a missing tag. For example, in:Chris Lattner
struct xyz { int y; }; enum abc { ZZZ }; static xyz b; abc c; we used to produce: t2.c:4:8: error: unknown type name 'xyz' static xyz b; ^ t2.c:5:1: error: unknown type name 'abc' abc c; ^ we now produce: t2.c:4:8: error: use of tagged type 'xyz' without 'struct' tag static xyz b; ^ struct t2.c:5:1: error: use of tagged type 'abc' without 'enum' tag abc c; ^ enum GCC produces the normal: t2.c:4: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘b’ t2.c:5: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘c’ rdar://6783347 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68914 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-12fix a valgrind problem I noticed while developing another patch,Chris Lattner
if a decl is invalid, it isn't added to the Decls array, so we need to pass in Decls.size() to avoid reading uninit memory. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68913 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-12Implement the first set of changes for PR3963 and rdar://6759604,Chris Lattner
which tries to do better error recovery when it is "obvious" that an identifier is a mis-typed typename. In this case, we try to parse it as a typename instead of as the identifier in a declarator, which gives us several options for better error recovery and immediately makes diagnostics more useful. For example, we now produce: t.c:4:8: error: unknown type name 'foo_t' static foo_t a = 4; ^ instead of: t.c:4:14: error: invalid token after top level declarator static foo_t a = 4; ^ Also, since we now parse "a" correctly, we make a decl for it, preventing later uses of 'a' from emitting things like: t.c:12:20: error: use of undeclared identifier 'a' int bar() { return a + b; } ^ I'd really appreciate any scrutiny possible on this, it is a tricky area. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68911 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-12Parse deleted member functions. Parsing member declarations goes through a ↵Sebastian Redl
different code path that I forgot previously. Implement the rvalue reference overload dance for returning local objects. Returning a local object first tries to find a move constructor now. The error message when no move constructor is defined (or is not applicable) and the copy constructor is deleted is quite ugly, though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68902 91177308-0d34-0410-b5e6-96231b3b80d8
