2012-01-07More lambda work: semantic analysis of capturing 'this'. It's a bit ↵Eli Friedman
complicated, but we have to be careful about when exactly captures are marked given PotentiallyPotentiallyEvaluated contexts.

2012-01-05More lambda work. Tweak the Sema interface slightly. Start adding the ↵Eli Friedman

2012-01-04Add an explicit LambdaExprContext to Declarator, to parallel ↵Eli Friedman

2012-01-04Stub out the Sema interface for lambda expressions, and change the parser to ↵Eli Friedman

2011-10-25Introduce a placeholder type for "pseudo object"John McCall
expressions: expressions which refer to a logical rather than a physical l-value, where the logical object is actually accessed via custom getter/setter code. A subsequent patch will generalize the AST for these so that arbitrary "implementing" sub-expressions can be provided. Right now the only client is ObjC properties, but this should be generalizable to similar language features, e.g. Managed C++'s __property methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142914 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25Check for unexpanded parameter packs in the name that guards aDouglas Gregor
Microsoft __if_exists/__if_not_exists statement. Also note that we weren't traversing DeclarationNameInfo *at all* within the RecursiveASTVisitor, which would be rather fatal for variadic templates. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142906 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25Implement support for dependent Microsoft __if_exists/__if_not_existsDouglas Gregor
statements. As noted in the documentation for the AST node, the semantics of __if_exists/__if_not_exists are somewhat different from the way Visual C++ implements them, because our parsed-template representation can't accommodate VC++ semantics without serious contortions. Hopefully this implementation is "good enough". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142901 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-24Rework Microsoft __if_exists/__if_not_exists parsing and semanticDouglas Gregor
analysis to separate dependent names from non-dependent names. For dependent names, we'll behave differently from Visual C++: - For __if_exists/__if_not_exists at class scope, we'll just warn and then ignore them. - For __if_exists/__if_not_exists in statements, we'll treat the inner statement as a compound statement, which we only instantiate in templates where the dependent name (after instantiation) exists. This behavior is different from VC++, but it's as close as we can get without encroaching ridiculousness. The latter part (dependent statements) is not yet implemented. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142864 91177308-0d34-0410-b5e6-96231b3b80d8

case situations with the unary operators & and *. Also extend the array bounds checking to work with pointer arithmetic; the pointer arithemtic checking can be turned on using -Warray-bounds-pointer-arithmetic. The changes to where CheckArrayAccess gets called is based on some trial & error and a bunch of digging through source code and gdb backtraces in order to have the check performed under as many situations as possible (such as for variable initializers, arguments to function calls, and within conditional in addition to the simpler cases of the operands to binary and unary operator) while not being called--and triggering warnings--more than once for a given ArraySubscriptExpr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136997 91177308-0d34-0410-b5e6-96231b3b80d8
