2012-04-30Remove the ref/value inconsistency in filter_decl_iterator.David Blaikie
filter_decl_iterator had a weird mismatch where both op* and op-> returned T* making it difficult to generalize this filtering behavior into a reusable library of any kind. This change errs on the side of value, making op-> return T* and op* return T&.

2012-03-11Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie
(Lex to AST). The member variable is always "LangOpts" and the member function is always "getLangOpts". Reviewed by Chris Lattner git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152536 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-01Implement "optimization" for lambda-to-block conversion which inlines the ↵Eli Friedman
generated block literal for lambdas which are immediately converted to block pointer type. This simplifies the AST, avoids an unnecessary copy of the lambda and makes it much easier to avoid copying the result onto the heap. Note that this transformation has a substantial semantic effect outside of ARC: it gives the converted lambda lifetime semantics similar to a block literal. With ARC, the effect is much less obvious because the lifetime of blocks is already managed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151797 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-26Ensure that we delete destructors in the right cases. Specifically:Richard Smith
- variant members with nontrivial destructors make the containing class's destructor deleted - check for a virtual destructor after checking for overridden methods in the base class(es) - check for an inaccessible operator delete for a class with a virtual destructor. Do not try to call an anonymous union field's destructor from the destructor of the containing class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151483 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-17Whether an argument is required (in contrast with being anJohn McCall
optional argument passed through the variadic ellipsis) potentially affects how we need to lower it. Propagate this information down to the various getFunctionInfo(...) overloads on CodeGenTypes. Furthermore, rename those overloads to clarify their distinct purposes, and make sure we're calling the right one in the right place. This has a nice side-effect of making it easier to construct a function type, since the 'variadic' bit is no longer separable. This shouldn't really change anything for our existing platforms, with one minor exception --- we should now call variadic ObjC methods with the ... in the "right place" (see the test case), which I guess matters for anyone running GNUStep on MIPS. Mostly it's just a substantial clean-up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150788 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-17Rework the Sema/AST/IRgen dance for the lambda closure type'sDouglas Gregor
conversion to function pointer. Rather than having IRgen synthesize the body of this function, we instead introduce a static member function "__invoke" with the same signature as the lambda's operator() in the AST. Sema then generates a body for the conversion to function pointer which simply returns the address of __invoke. This approach makes it easier to evaluate a call to the conversion function as a constant, makes the linkage of the __invoke function follow the normal rules for member functions, and may make life easier down the road if we ever want to constexpr'ify some of lambdas. Note that IR generation is responsible for filling in the body of __invoke (Sema just adds a dummy body), because the body can't generally be expressed in C++.
