2010-09-16Implement automatic bracket insertion for Objective-C class messageDouglas Gregor
sends. These are far trickier than instance messages, because we typically have something like NSArray alloc] where it appears to be a declaration of a variable named "alloc" up until we see the ']' (or a ':'), and at that point we can't backtrace. So, we use a combination of syntactic and semantic disambiguation to treat this as a message send only when the type is an Objective-C type and it has the syntax of a class message send (which would otherwise be ill-formed). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114057 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-20Another step in the process of making the parser depend on Sema:John McCall
- move DeclSpec &c into the Sema library - move ParseAST into the Parse library Reflect this change in a thousand different includes. Reflect this change in the link orders. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111667 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-15When we're performing tentative parsing to determine whether theDouglas Gregor
parser is looking at a declaration or an expression, use a '=' to conclude that we are parsing a declaration. This is wrong. However, our previous approach of finding a comma after the '=' is also wrong, because the ',' could be part of a template-argument-list. So, for now we're going to use the same wrong heuristic as GCC and Visual C++, because less real-world code is likely to be broken this way. I've opened PR7655 to keep track of our wrongness; note also the XFAIL'd test. Fixes <rdar://problem/8193163>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108459 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-26Fix an assertion-on-error during tentative constructor parsing byJohn McCall
propagating error conditions out of the various annotate-me-a-snowflake routines. Generally (but not universally) removes redundant diagnostics as well as, you know, not crashing on bad code.

2009-11-21Added rudimentary C++0x attribute support.Sean Hunt
The following attributes are currently supported in C++0x attribute lists (and in GNU ones as well): - align() - semantics believed to be conformant to n3000, except for redeclarations and what entities it may apply to - final - semantics believed to be conformant to CWG issue 817's proposed wording, except for redeclarations - noreturn - semantics believed to be conformant to n3000, except for redeclarations - carries_dependency - currently ignored (this is an optimization hint) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89543 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-25Improve support for out-of-line definitions of nested templates andDouglas Gregor
their members, including member class template, member function templates, and member classes and functions of member templates. To actually parse the nested-name-specifiers that qualify the name of an out-of-line definition of a member template, e.g., template<typename X> template<typename Y> X Outer<X>::Inner1<Y>::foo(Y) { return X(); } we need to look for the template names (e.g., "Inner1") as a member of the current instantiation (Outer<X>), even before we have entered the scope of the current instantiation. Since we can't do this in general (i.e., we should not be looking into all dependent nested-name-specifiers as if they were the current instantiation), we rely on the parser to tell us when it is parsing a declaration specifier sequence, and, therefore, when we should consider the current scope specifier to be a current instantiation. Printing of complicated, dependent nested-name-specifiers may be somewhat broken by this commit; I'll add tests for this issue and fix the problem (if it still exists) in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80044 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-27Initial implementation of parsing, semantic analysis, and templateDouglas Gregor
instantiation for C++ typename-specifiers such as typename T::type The parsing of typename-specifiers is relatively easy thanks to annotation tokens. When we see the "typename", we parse the typename-specifier and produce a typename annotation token. There are only a few places where we need to handle this. We currently parse the typename-specifier form that terminates in an identifier, but not the simple-template-id form, e.g., typename T::template apply<U, V> Parsing of nested-name-specifiers has a similar problem, since at this point we don't have any representation of a class template specialization whose template-name is unknown. Semantic analysis is only partially complete, with some support for template instantiation that works for simple examples. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67875 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-27Fix rdar://6719156 - clang should emit a better error when blocks are ↵Chris Lattner

2009-02-10Teach the type-id/expression disambiguator about differentDouglas Gregor
disambiguation contexts, so that we properly parse template arguments such as A<int()> as type-ids rather than as expressions. Since this can be confusing (especially when the template parameter is a non-type template parameter), we try to give a friendly error message. Almost, eliminate a redundant error message (that should have been a note) and add some ultra-basic checks for non-type template arguments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64189 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-05Found a subtle bug caused by an implicit enum-to-bool conversion (of the ↵Argyrios Kyrtzidis
TentativeParsingResult enum). This was the motivation of the following changes: -'TentativeParsingResult' enum is replaced by a 'TPResult' class that basically encapsulates the enum. -TPR_true, TPR_false, TPR_ambiguous, and TPR_error enum constants are replaced by TPResult::True(), TPResult::False(), etc. calls that return a TPResult object. -Also fixed the subtle bug in Parser::isCXXFunctionDeclarator (caught by the above changes as a compilation error). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57125 91177308-0d34-0410-b5e6-96231b3b80d8
