2012-02-18Implement constant expression support for __real__ and __imag__ on lvalueRichard Smith
complex numbers. Treat complex numbers as arrays of the corresponding component type, in order to make std::complex behave properly if implemented in terms of _Complex T. Apparently libstdc++'s std::complex is implemented this way, and we were rejecting a member like this: constexpr double real() { return __real__ val; } because it was marked constexpr but unable to produce a constant expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150895 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
2012-02-18Unify our computation of the type of a captured reference to aDouglas Gregor

2012-02-18Diagnose uses of deleted destructors and inaccessible defaulted destructors.Richard Smith
We had two separate issues here: firstly, varions functions were assuming that they did not need to perform semantic checks on trivial destructors (this is not true in C++11, where a trivial destructor can nonetheless be private or deleted), and a bunch of DiagnoseUseOfDecl calls were missing for uses of destructors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150866 91177308-0d34-0410-b5e6-96231b3b80d8

decent diagnostics. Finish the work of combining all the 'ShouldDelete' functions into one. In unifying the code, fix a minor bug where an anonymous union with a deleted default constructor as a member of a union wasn't being considered as making the outer union's default constructor deleted. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150862 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-17Don't allow non-empty ParenListExprs as array-new initializers.Sebastian Redl

2012-02-17Basic code generation support for std::initializer_list.Sebastian Redl
We now generate temporary arrays to back std::initializer_list objects initialized with braces. The initializer_list is then made to point at the array. We support both ptr+size and start+end forms, although the latter is untested. Array lifetime is correct for temporary std::initializer_lists (e.g. call arguments) and local variables. It is untested for new expressions and member initializers. Things left to do: Massively increase the amount of testing. I need to write tests for start+end init lists, temporary objects created as a side effect of initializing init list objects, new expressions, member initialization, creation of temporary objects (e.g. std::vector) for initializer lists, and probably more. Get lifetime "right" for member initializers and new expressions. Not that either are very useful. Implement list-initialization of array new expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150803 91177308-0d34-0410-b5e6-96231b3b80d8
