2011-12-31Implement support for module requirements, which indicate the languageDouglas Gregor
features needed for a particular module to be available. This allows mixed-language modules, where certain headers only work under some language variants (e.g., in C++, std.tuple might only be available in C++11 mode). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147387 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-20When performing name lookup for a redeclaration, ignore moduleDouglas Gregor
visibility restrictions. This ensures that all declarations of the same entity end up in the same redeclaration chain, even if some of those declarations aren't visible. While this may seem unfortunate to some---why can't two C modules have different functions named 'f'?---it's an acknowedgment that a module does not introduce a new "namespace" of names. As part of this, stop merging the 'module-private' bit from previous declarations to later declarations, because we want each declaration in a module to stand on its own because this can effect, for example, submodule visibility. Note that this notion of names that are invisible to normal name lookup but are available for redeclaration lookups is how we should implement friend declarations and extern declarations within local function scopes. I'm not tackling that problem now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146980 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-20Detect when mapping a #include/#import over to a submodule ends upDouglas Gregor
hitting a submodule that was never actually created, e.g., because that header wasn't parsed. In such cases, complain (because the module's umbrella headers don't cover everything) and fall back to including the header. Later, we'll add a warning at module-build time to catch all such cases. However, this fallback is important to eliminate assertions in the ASTWriter when this happens. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146933 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-19constexpr handling improvements. Produce detailed diagnostics when a 'constexpr'Richard Smith
variable is initialized by a non-constant expression, and pass in the variable being declared so that earlier-initialized fields' values can be used. Rearrange VarDecl init evaluation to make this possible, and in so doing fix a long-standing issue in our C++ constant expression handling, where we would mishandle cases like: extern const int a; const int n = a; const int a = 5; int arr[n]; Here, n is not initialized by a constant expression, so can't be used in an ICE, even though the initialization expression would be an ICE if it appeared later in the TU. This requires computing whether the initializer is an ICE eagerly, and saving that information in PCH files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146856 91177308-0d34-0410-b5e6-96231b3b80d8
