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.

2012-05-01Clean up changes suggested by Douglas Gregor:Patrick Beard
BuildObjCNumericLiteral() and BuildObjCBoxedExpr() now both using PerformCopyInitialization() rather than PerformImplicitConversion(), which suppresses errors. In BuildObjCBoxedExpr(): no longer calling .getCanonicalType(), ValueType->getAs() will remove the minimal amount of sugar.

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

2012-02-18Rewrite variable capture within lambda expressions and blocks,Douglas Gregor
eliminating a bunch of redundant code and properly modeling how the captures of outside blocks/lambdas affect the types seen by inner captures. This new scheme makes two passes over the capturing scope stack. The first pass goes up the stack (from innermost to outermost), assessing whether the capture looks feasible and stopping when it either hits the scope where the variable is declared or when it finds an existing capture. The second pass then walks down the stack (from outermost to innermost), capturing the variable at each step and updating the captured type and the type that an expression referring to that captured variable would see. It also checks type-specific restrictions, such as the inability to capture an array within a block. Note that only the first odr-use of each variable needs to do the full walk; subsequent uses will find the capture immediately, so multiple walks need not occur. The same routine that builds the captures can also compute the type of the captures without signaling errors and without actually performing the capture. This functionality is used to determine the type of declaration references as well as implementing the weird decltype((x)) rule within lambda expressions. The capture code now explicitly takes sides in the debate over C++ core issue 1249, which concerns the type of captures within nested lambdas. We opt to use the more permissive, more useful definition implemented by GCC rather than the one implemented by EDG. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150875 91177308-0d34-0410-b5e6-96231b3b80d8

rdar://10289283 Also fix the fixit (oh the irony) when it uses CFBridgingRetain/CFBridgingRelease; they are supposed to be calls with the casted expression as parameter, they should not be inserted into the cast like the __bridge keywords. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150705 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-01Improve checking of explicit captures in a C++11 lambda expression:Douglas Gregor
- Actually building the var -> capture mapping properly (there was an off-by-one error) - Keeping track of the source location of each capture - Minor QoI improvements, e.g, highlighing the prior capture if there are multiple captures, pointing at the variable declaration we found if we reject it. As part of this, add standard citations for the various semantic checks we perform, and note where we're not performing those checks as we should. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149462 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-15Move the definition-specific data of ObjCInterfaceDecl into aDouglas Gregor
separately-allocated DefinitionData structure, which we manage the same way as CXXRecordDecl::DefinitionData. This prepares the way for making ObjCInterfaceDecls redeclarable, to more accurately model forward declarations of Objective-C classes and eliminate the mutation of ObjCInterfaceDecl that causes us serious trouble in the AST reader. Note that ObjCInterfaceDecl's accessors are fairly robust against being applied to forward declarations, because Clang (and Sema in particular) doesn't perform RequireCompleteType/hasDefinition() checks everywhere it has to. Each of these overly-robust cases is marked with a FIXME, which we can tackle over time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146644 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
