2012-02-22Generate an AST for the conversion from a lambda closure type to aDouglas Gregor
block pointer that returns a block literal which captures (by copy) the lambda closure itself. Some aspects of the block literal are left unspecified, namely the capture variable (which doesn't actually exist) and the body (which will be filled in by IRgen because it can't be written as an AST). Because we're switching to this model, this patch also eliminates tracking the copy-initialization expression for the block capture of the conversion function, since that information is now embedded in the synthesized block literal. -1 side tables FTW. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151131 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-22Implement C++11 [expr.call]p11: If the operand to a decltype-specifier is aRichard Smith
function call (or a comma expression with a function call on its right-hand side), possibly parenthesized, then the return type is not required to be complete and a temporary is not bound. Other subexpressions inside a decltype expression do not get this treatment. This is implemented by deferring the relevant checks for all calls immediately within a decltype expression, then, when the expression is fully-parsed, checking the relevant constraints and stripping off any top-level temporary binding. Deferring the completion of the return type exposed a bug in overload resolution where completion of the argument types was not attempted, which is also fixed by this change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151117 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-21In the conflict between C++11 [expr.prim.general]p4, which declaresDouglas Gregor
that 'this' can be used in the brace-or-equal-initializer of a non-static data member, and C++11 [expr.prim.lambda]p9, which says that lambda expressions not in block scope can have no captures, side fully with C++11 [expr.prim.general]p4 by allowing 'this' to be captured within these initializers. This seems to be the intent of non-static data member initializers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151101 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-21Improve our handling of lambda expressions that occur within defaultDouglas Gregor
arguments. There are two aspects to this: - Make sure that when marking the declarations referenced in a default argument, we don't try to mark local variables, both because it's a waste of time and because the semantics are wrong: we're not in a place where we could capture these variables again even if it did make sense. - When a lambda expression occurs in a default argument of a function template, make sure that the corresponding closure type is considered dependent, so that it will get properly instantiated. The second bit is a bit of a hack; to fix it properly, we may have to rearchitect our handling of default arguments, parsing them only after creating the function definition. However, I'd like to separate that work from the lambdas work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151076 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-21Implement name mangling for lambda expressions that occur within theDouglas Gregor
default arguments of function parameters. This simple-sounding task is complicated greatly by two issues: (1) Default arguments aren't actually a real context, so we need to maintain extra state within lambda expressions to track when a lambda was actually in a default argument. (2) At the time that we parse a default argument, the FunctionDecl doesn't exist yet, so lambda closure types end up in the enclosing context. It's not clear that we ever want to change that, so instead we introduce the notion of the "effective" context of a declaration for the purposes of name mangling. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151011 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-20[PCH] Recover gracefully if the ASTReader detects that a file is differentArgyrios Kyrtzidis
from the one stored in the PCH/AST, while trying to load a SLocEntry. We verify that all files of the PCH did not change before loading it but this is not enough because: - The AST may have been 1) kept around, 2) to do queries on it. - We may have 1) verified the PCH and 2) started parsing. Between 1) and 2) files may change and we are going to have crashes because the rest of clang cannot deal with the ASTReader failing to read a SLocEntry. Handle this by recovering gracefully in such a case, by initializing the SLocEntry with the info from the PCH/AST as well as reporting failure by the ASTReader. rdar://10888929 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151004 91177308-0d34-0410-b5e6-96231b3b80d8
