Substantially improve error recovery after broken if conditions by parsing the full if when we have a semantic error instead of using parser recovery techniques to recover from a semantic error.

the type of the enumeration once the enumeration has been defined. Fix the overloading test-case to properly create enums that promote the way we want them to. Implement C++0x promotions from enumeration types to long long/unsigned long long. We're using these promotions in Carbon.h (since long long is a common extension).

2008-12-11PTH:Ted Kremenek
- Added a side-table per each token-cached file with the preprocessor conditional stack. This tracks what #if's are matched with what #endifs and where their respective tokens are in the PTH file. This will allow for quick skipping of excluded conditional branches in the Preprocessor. - Performance testing shows the addition of this information (without actually utilizing it) leads to no performance regressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60911 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-11Unifies the name-lookup mechanisms used in various parts of the ASTDouglas Gregor
and separates lexical name lookup from qualified name lookup. In particular: * Make DeclContext the central data structure for storing and looking up declarations within existing declarations, e.g., members of structs/unions/classes, enumerators in C++0x enums, members of C++ namespaces, and (later) members of Objective-C interfaces/implementations. DeclContext uses a lazily-constructed data structure optimized for fast lookup (array for small contexts, hash table for larger contexts). * Implement C++ qualified name lookup in terms of lookup into DeclContext. * Implement C++ unqualified name lookup in terms of qualified+unqualified name lookup (since unqualified lookup is not purely lexical in C++!) * Limit the use of the chains of declarations stored in IdentifierInfo to those names declared lexically. * Eliminate CXXFieldDecl, collapsing its behavior into FieldDecl. (FieldDecl is now a ScopedDecl). * Make RecordDecl into a DeclContext and eliminates its Members/NumMembers fields (since one can just iterate through the DeclContext to get the fields). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60878 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-10PreprocessorLexer (and subclasses):Ted Kremenek
- Added virtual method 'getSourceLocation()' (no arguments) that gets the location of the next "observable" location (e.g., next character, next token). PPLexerChange.cpp: - Implemented FIXME by using PreprocessorLexer::getSourceLocation() to get the location in the file we are returning to after lexing a #included file. This appears to be slightly faster than having the branch (i.e., 'if(CurLexer)'). It's also not a really hot part of the Preprocessor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60860 91177308-0d34-0410-b5e6-96231b3b80d8
