2012-04-03Replace the workaround from r153445 with a proper fix.Kaelyn Uhrain
Infinite recursion was happening when DiagnoseInvalidRedeclaration called ActOnFunctionDeclarator to check if a typo correction works when the correction was just to the nested-name-specifier because the wrong DeclContext was being passed in. Unlike a number of functions surrounding typo correction, the DeclContext passed in for a function is the context of the function name after applying any nested name specifiers, not the lexical DeclContext where the function+nested-name-specifier appears. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153962 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-03Correct handling of _Pragma macro inside a macro argument.Argyrios Kyrtzidis
If we are pre-expanding a macro argument don't actually "activate" the pragma at that point, activate the pragma whenever we encounter it again in the token stream. This ensures that we will activate it in the correct location or that we will ignore it if it never enters the token stream, e.g: \#define EMPTY(x) \#define INACTIVE(x) EMPTY(x) INACTIVE(_Pragma("clang diagnostic ignored \"-Wconversion\"")) This also fixes the crash in rdar://11168596. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153959 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-03Change location information for synthesized properties to be at theEric Christopher
property file/line rather than the @synthesize file/line. Avoids some nasty confusing-ness with conflating the file from the scope and the line from the original declaration. Use the current scope location as a separate parameter so that we can match it up better in the line table with the beginning of the scope. Update a couple of testcases accordingly since I had to change that we actually use the passed in location in EmitFunctionStart and for the new metadata parameter and add a new testcase to make sure we've got the right line numbers for synthesized properties.

2012-04-02Correct error recovery when missing 'class' in a template template parameter.David Blaikie
The diagnostic message correctly informs the user that they have omitted the 'class' keyword, but neither suggests this insertion as a fixit, nor attempts to recover as if they had provided the keyword. This fixes the recovery, adds the fixit, and adds a separate diagnostic and corresponding replacement fixit for cases where the user wrote 'struct' or 'typename' instead of 'class' (suggested by Richard Smith as a possible common mistake). I'm not sure the diagnostic message for either the original or new cases feel very Clang-esque, so I'm open to suggestions there. The fixit hints make it fairly easy to see what's required, though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153887 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-30Revert r153723, and its follow-ups r153728 and r153733.Chandler Carruth
These patches cause us to miscompile and/or reject code with static function-local variables in an extern-C context. Previously, we were papering over this as long as the variables are within the same translation unit, and had not seen any failures in the wild. We still need a proper fix, which involves mangling static locals inside of an extern-C block (as GCC already does), but this patch causes pretty widespread regressions. Firefox, and many other applications no longer build. Lots of test cases have been posted to the list in response to this commit, so there should be no problem reproducing the issues. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153768 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-30If we encounter a friend class template for which we cannot resolveDouglas Gregor
the nested-name-specifier (e.g., because it is dependent), do not error even though we can't represent it in the AST at this point. This is a horrible, horrible hack. The actual feature we still need to implement (for C++98!) is covered by PR12292. However, we used to silently accept this code, so when we recently started rejecting it we caused some regressions (e.g., <rdar://problem/11147355>).
