2013-04-20C++1y: Allow aggregates to have default initializers.Richard Smith
Add a CXXDefaultInitExpr, analogous to CXXDefaultArgExpr, and use it both in CXXCtorInitializers and in InitListExprs to represent a default initializer. There's an additional complication here: because the default initializer can refer to the initialized object via its 'this' pointer, we need to make sure that 'this' points to the right thing within the evaluation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179958 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-18Replace TypeLoc llvm::cast support to be well-defined.David Blaikie
The TypeLoc hierarchy used the llvm::cast machinery to perform undefined behavior by casting pointers/references to TypeLoc objects to derived types and then using the derived copy constructors (or even returning pointers to derived types that actually point to the original TypeLoc object). Some context is in this thread: http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-December/056804.html Though it's spread over a few months which can be hard to read in the mail archive. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175462 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-20Rework implementation of DR1492: Apply the resolution to operator delete too,Richard Smith
since it also has an implicit exception specification. Downgrade the error to an extwarn, since at least for operator delete, system headers like to declare it as 'noexcept' whereas the implicit definition does not have an explicit exception specification. Move the exception specification for user-declared 'operator delete' functions from the type-as-written into the type, to reflect reality and to allow us to detect whether there was an implicit exception spec or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166372 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-16Store SourceManager pointer on PrintingPolicy in the case where we're dumping,Richard Smith
and remove ASTContext reference (which was frequently bound to a dereferenced null pointer) from the recursive lump of printPretty functions. In so doing, fix (at least) one case where we intended to use the 'dump' mode, but that failed because a null ASTContext reference had been passed in. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162011 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-27Final piece of core issue 1330: delay computing the exception specification ofRichard Smith
a defaulted special member function until the exception specification is needed (using the same criteria used for the delayed instantiation of exception specifications for function temploids). EST_Delayed is now EST_Unevaluated (using 1330's terminology), and, like EST_Uninstantiated, carries a pointer to the FunctionDecl which will be used to resolve the exception specification. This is enabled for all C++ modes: it's a little faster in the case where the exception specification isn't used, allows our C++11-in-C++98 extensions to work, and is still correct for C++98, since in that mode the computation of the exception specification can't fail. The diagnostics here aren't great (in particular, we should include implicit evaluation of exception specifications for defaulted special members in the template instantiation backtraces), but they're not much worse than before. Our approach to the problem of cycles between in-class initializers and the exception specification for a defaulted default constructor is modified a little by this change -- we now reject any odr-use of a defaulted default constructor if that constructor uses an in-class initializer and the use is in an in-class initialzer which is declared lexically earlier. This is a closer approximation to the current draft solution in core issue 1351, but isn't an exact match (but the current draft wording isn't reasonable, so that's to be expected). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160847 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-04Move Sema::RequireCompleteType() and Sema::RequireCompleteExprType()Douglas Gregor
off PartialDiagnostic. PartialDiagnostic is rather heavyweight for something that is in the critical path and is rarely used. So, switch over to an abstract-class-based callback mechanism that delays most of the work until a diagnostic is actually produced. Good for ~11k code size reduction in the compiler and 1% speedup in -fsyntax-only on the code in <rdar://problem/11004361>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156176 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
