2011-07-22In Objective-C, pull arbitrary attributes from overriddenJohn McCall
methods, including indirectly overridden methods like those declared in protocols and categories. There are mismatches that we would like to diagnose but aren't yet, but this is fine for now. I looked at approaches that avoided doing this lookup unless we needed it, but the infer-related-result-type checks were doing it anyway, so I left it with the same fast-path check for no previous declartions of that selector. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135743 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-15Create a new expression node, SubstNonTypeTemplateParmExpr,John McCall
to represent a fully-substituted non-type template parameter. This should improve source fidelity, as well as being generically useful for diagnostics and such. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135243 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-07In ARC, reclaim all return values of retainable type, not just thoseJohn McCall
where we have an immediate need of a retained value. As an exception, don't do this when the call is made as the immediate operand of a __bridge retain. This is more in the way of a workaround than an actual guarantee, so it's acceptable to be brittle here. rdar://problem/9504800 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134605 91177308-0d34-0410-b5e6-96231b3b80d8

types we don't model, to distinguish them from uninitialized arrays (PR10163). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133937 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. Addresses <rdar://problem/9552231>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133521 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-15Automatic Reference Counting.John McCall
Language-design credit goes to a lot of people, but I particularly want to single out Blaine Garst and Patrick Beard for their contributions. Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself, in no particular order. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133103 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-15[analyzer] When performing a binary operation on symbolic operands, we ↵Jordy Rose
convert the symbol values to a common type. But in a relational operation, the result is an 'int' or 'bool', which may not be the appropriate type to convert the operands to. In these cases, use the left-hand operand's type as the conversion type. There's no associated test for this because fully-constrained symbolic values are evaluated ahead of time in normal expressions. This can only come up in checker-constructed expressions (like the ones in an upcoming patch to CStringChecker). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133041 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-10[analyzer] PR8962 again. Ban ParenExprs (and friends) from block-level ↵Jordy Rose
expressions (by calling IgnoreParens before adding expressions to blocks). Undo 132769 (LiveVariables' local IgnoreParens), since it's no longer necessary. Also, have Environment stop looking through NoOp casts; it didn't match the behavior of LiveVariables. And once that's gone, the whole cast block of that switch is unnecessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@132840 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-06Modify some deleted function methods to better reflect reality:Sean Hunt
- New isDefined() function checks for deletedness - isThisDeclarationADefinition checks for deletedness - New doesThisDeclarationHaveABody() does what isThisDeclarationADefinition() used to do - The IsDeleted bit is not propagated across redeclarations - isDeleted() now checks the canoncial declaration - New isDeletedAsWritten() does what it says on the tin. - isUserProvided() now correct (thanks Richard!)
