2012-04-17Nicer display of unprintable source, and fix caret display for non-ascii textSeth Cantrell
Unprintable source in diagnostics is transformed to a printable form and then displayed with reversed colors if possible. Unprintable characters are displayed as <U+NNNN> while bytes that do not represent valid characters are shown as <XX>. Column adjustments to diagnostic carets, highlighted ranges, and fixups are made both for characters escaped as above and for characters which are printable but take up more than a single column. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154946 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-17Switches the JSONCompilationDatabase to use the YAML parser.Manuel Klimek
This will allow us to delete the JSON parser from llvm. The biggest change is a general change of strategy - instead of storing StringRef's to the values for the command line and directory in the input buffer, we store ScalarNode*'s. The reason is that the YAML parser's getRawValue on ScalarNodes returns a string that includes the quotes in case of double quoted strings. For the same reason we're removing the JSON parsing part of the command line parsing - this means an extra copy for a command line when it is requested (and only when it is requested). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154929 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-17Implement DR1330 in C++11 mode, to support libstdc++4.7 which uses it.Richard Smith
We have a new flavor of exception specification, EST_Uninstantiated. A function type with this exception specification carries a pointer to a FunctionDecl, and the exception specification for that FunctionDecl is instantiated (if needed) and used in the place of the function type's exception specification. When a function template declaration with a non-trivial exception specification is instantiated, the specialization's exception specification is set to this new 'uninstantiated' kind rather than being instantiated immediately. Expr::CanThrow has migrated onto Sema, so it can instantiate exception specs on-demand. Also, any odr-use of a function triggers the instantiation of its exception specification (the exception specification could be needed by IRGen). In passing, fix two places where a DeclRefExpr was created but the corresponding function was not actually marked odr-used. We used to get away with this, but don't any more. Also fix a bug where instantiating an exception specification which refers to function parameters resulted in a crash. We still have the same bug in default arguments, which I'll be looking into next. This, plus a tiny patch to fix libstdc++'s common_type, is enough for clang to parse (and, in very limited testing, support) all of libstdc++4.7's standard headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154886 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-16Implement C++11 [expr.prim.general]p3, which permits the use of 'this'Douglas Gregor
in the declaration of a non-static member function after the (optional) cv-qualifier-seq, which in practice means in the exception specification and late-specified return type. The new scheme here used to manage 'this' outside of a member function scope is more general than the Scope-based mechanism previously used for non-static data member initializers and late-parsesd attributes, because it can also handle the cv-qualifiers on the member function. Note, however, that a separate pass is required for static member functions to determine whether 'this' was used, because we might not know that we have a static function until after declaration matching. Finally, this introduces name mangling for 'this' and for the implicit 'this', which is intended to match GCC's mangling. Independent verification for the new mangling test case would be appreciated. Fixes PR10036 and PR12450. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154799 91177308-0d34-0410-b5e6-96231b3b80d8
