2010-09-18Problem with gnu conditional extension with missingFariborz Jahanian
LHS and when conditional expression is an array. Since it will be decayed, saved expression must be saved with decayed expression. This is necessary to preserve semantics of this extension (and prevent an IRGen crash which expects an array to always be decayed). I am sure there will be other cases in c++ (aggregate conditionals for example) when saving of the expression must happen after some transformation on conditional expression has happened. Doug, please review. Fixes // rdar://8446940 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114296 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-14When marking the declarations in a default argument expression asDouglas Gregor
"used", at the time that the default argument itself is used, also mark destructors that will be called by this expression. This fixes a regression that I introduced in r113700, which broke WebKit, and fixes <rdar://problem/8427926>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113883 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-11When parsing default function arguments, do not mark any declarationsDouglas Gregor
used in the default function argument as "used". Instead, when we actually use the default argument, make another pass over the expression to mark any used declarations as "used" at that point. This addresses two kinds of related problems: 1) We were marking some declarations "used" that shouldn't be, because we were marking them too eagerly. 2) We were failing to mark some declarations as "used" when we should, if the first time it was instantiated happened to be an unevaluated context, we wouldn't mark them again at a later point. I've also added a potentially-handy visitor class template EvaluatedExprVisitor, which only visits the potentially-evaluated subexpressions of an expression. I bet this would have been useful for noexcept... Fixes PR5810 and PR8127. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113700 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-29Implement C++0x user-defined string literals.Sean Hunt
The extra data stored on user-defined literal Tokens is stored in extra allocated memory, which is managed by the PreprocessorLexer because there isn't a better place to put it that makes sure it gets deallocated, but only after it's used up. My testing has shown no significant slowdown as a result, but independent testing would be appreciated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112458 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-28Fix the memory leak of FloatingLiteral/IntegerLiteral.Argyrios Kyrtzidis
For large floats/integers, APFloat/APInt will allocate memory from the heap to represent these numbers. Unfortunately, when we use a BumpPtrAllocator to allocate IntegerLiteral/FloatingLiteral nodes the memory associated with the APFloat/APInt values will never get freed. I introduce the class 'APNumericStorage' which uses ASTContext's allocator for memory allocation and is used internally by FloatingLiteral/IntegerLiteral.

2010-08-27Propagate whether an id-expression is the immediate argument ofJohn McCall
an '&' expression from the second caller of ActOnIdExpression. Teach template argument deduction that an overloaded id-expression doesn't give a valid type for deduction purposes to a non-static member function unless the expression has the correct syntactic form. Teach ActOnIdExpression that it shouldn't try to create implicit member expressions for '&function', because this isn't a permitted form of use for member functions. Teach CheckAddressOfOperand to diagnose these more carefully. Some of these cases aren't reachable right now because earlier diagnostics interrupt them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112258 91177308-0d34-0410-b5e6-96231b3b80d8
