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

2012-06-07Plug a long standing memory leak in TemplateArgument.Benjamin Kramer
The integral APSInt value is now stored in a decomposed form and the backing store for large values is allocated via the ASTContext. This way its not leaked as TemplateArguments are never destructed when they are allocated in the ASTContext. Since the integral data is immutable it is now shared between instances, making copying TemplateArguments a trivial operation. Currently getting the integral data out of a TemplateArgument requires creating a new APSInt object. This is cheap when the value is small but can be expensive if it's not. If this turns out to be an issue a more efficient accessor could be added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158150 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

2012-03-07AST representation for user-defined literals, plus just enough of semanticRichard Smith
analysis to make the AST representation testable. They are represented by a new UserDefinedLiteral AST node, which is a sugared CallExpr. All semantic properties, including full CodeGen support, are achieved for free by this representation. UserDefinedLiterals can never be dependent, so no custom instantiation behavior is required. They are mangled as if they were direct calls to the underlying literal operator. This matches g++'s apparent behavior (but not its actual mangling, which is broken for literal-operator-ids). User-defined *string* literals are now fully-operational, but the semantic analysis is quite hacky and needs more work. No other forms of user-defined literal are created yet, but the AST support for them is present. This patch committed after midnight because we had already hit the quota for new kinds of literal yesterday. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152211 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-06Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,Ted Kremenek
NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features. Docs are forthcoming to document the implementation and behavior of these features. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152137 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-24Implement a new type trait __is_trivially_constructible(T, Args...)Douglas Gregor
that provides the behavior of the C++11 library trait std::is_trivially_constructible<T, Args...>, which can't be implemented purely as a library. Since __is_trivially_constructible can have zero or more arguments, I needed to add Yet Another Type Trait Expression Class, this one handling arbitrary arguments. The next step will be to migrate UnaryTypeTrait and BinaryTypeTrait over to this new, more general TypeTrait class.

2012-02-16Revert "Make CXXNewExpr contain only a single initialier, and not hold the ↵Sebastian Redl

2012-02-16Make CXXNewExpr contain only a single initialier, and not hold the used ↵Sebastian Redl
constructor itself. Holding the constructor directly makes no sense when list-initialized arrays come into play. The constructor is now held in a CXXConstructExpr, if construction is what is done. The new design can also distinguish properly between list-initialization and direct-initialization, as well as implicit default-initialization constructors and explicit value-initialization constructors. Finally, doing it this way removes redundance from the AST because CXXNewExpr doesn't try to handle both the allocation and the initialization responsibilities. This breaks the static analysis of new expressions. I've filed PR12014 to track this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150682 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-06Change the AST representation of operations on Objective-CJohn McCall
property references to use a new PseudoObjectExpr expression which pairs a syntactic form of the expression with a set of semantic expressions implementing it. This should significantly reduce the complexity required elsewhere in the compiler to deal with these kinds of expressions (e.g. IR generation's special l-value kind, the static analyzer's Message abstraction), at the lower cost of specifically dealing with the odd AST structure of these expressions. It should also greatly simplify efforts to implement similar language features in the future, most notably Managed C++'s properties and indexed properties. Most of the effort here is in dealing with the various clients of the AST. I've gone ahead and simplified the ObjC rewriter's use of properties; other clients, like IR-gen and the static analyzer, have all the old complexity *and* all the new complexity, at least temporarily. Many thanks to Ted for writing and advising on the necessary changes to the static analyzer. I've xfailed a small diagnostics regression in the static analyzer at Ted's request. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143867 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-21Introduce a new AST node describing reference binding to temporaries.Douglas Gregor
MaterializeTemporaryExpr captures a reference binding to a temporary value, making explicit that the temporary value (a prvalue) needs to be materialized into memory so that its address can be used. The intended AST invariant here is that a reference will always bind to a glvalue, and MaterializeTemporaryExpr will be used to convert prvalues into glvalues for that binding to happen. For example, given const int& r = 1.0; The initializer of "r" will be a MaterializeTemporaryExpr whose subexpression is an implicit conversion from the double literal "1.0" to an integer value. IR generation benefits most from this new node, since it was previously guessing (badly) when to materialize temporaries for the purposes of reference binding. There are likely more refactoring and cleanups we could perform there, but the introduction of MaterializeTemporaryExpr fixes PR9565, a case where IR generation would effectively bind a const reference directly to a bitfield in a struct.

2011-02-17Change the representation of GNU ?: expressions to use a different expressionJohn McCall
class and to bind the shared value using OpaqueValueExpr. This fixes an unnoticed problem with deserialization of these expressions where the deserialized form would lose the vital pointer-equality trait; or rather, it fixes it because this patch also does the right thing for deserializing OVEs. Change OVEs to not be a "temporary object" in the sense that copy elision is permitted. This new representation is not totally unawkward to work with, but I think that's really part and parcel with the semantics we're modelling here. In particular, it's much easier to fix things like the copy elision bug and to make the CFG look right. I've tried to update the analyzer to deal with this in at least some obvious cases, and I think we get a much better CFG out, but the printing of OpaqueValueExprs probably needs some work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125744 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-17Step #1/N of implementing support for __label__: split labels intoChris Lattner
LabelDecl and LabelStmt. There is a 1-1 correspondence between the two, but this simplifies a bunch of code by itself. This is because labels are the only place where we previously had references to random other statements, causing grief for AST serialization and other stuff. This does cause one regression (attr(unused) doesn't silence unused label warnings) which I'll address next. This does fix some minor bugs: 1. "The only valid attribute " diagnostic was capitalized. 2. Various diagnostics printed as ''labelname'' instead of 'labelname' 3. This reduces duplication of label checking between functions and blocks. Review appreciated, particularly for the cindex and template bits. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125733 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-07A few more tweaks to the blocks AST representation: John McCall
- BlockDeclRefExprs always store VarDecls - BDREs no longer store copy expressions - BlockDecls now store a list of captured variables, information about how they're captured, and a copy expression if necessary With that in hand, change IR generation to use the captures data in blocks instead of walking the block independently. Additionally, optimize block layout by emitting fields in descending alignment order, with a heuristic for filling in words when alignment of the end of the block header is insufficient for the most aligned field. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125005 91177308-0d34-0410-b5e6-96231b3b80d8
