2011-10-13Implement the first piece of a -Wc++98-compat flag so that people can build inJeffrey Yasskin
C++11 mode but keep their sources compatible with C++98. This patch implements the -Wc++98-compat-variadic-templates sub-flag and -Wc++98-compat to include it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141898 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-13Allow for annotate attributes after access specifiers. When suchErik Verbruggen
attributes are found, propagate them to subsequent declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141861 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-12When we determine that a function template specialization produced asDouglas Gregor
part of template argument deduction is ill-formed, we mark it as invalid and treat it as a deduction failure. If we happen to find that specialization again, treat it as a deduction failure rather than silently building a call to the declaration. Fixes PR11117, a marvelous bug where deduction failed after creating an invalid specialization, causing overload resolution to pick a different candidate. Then we performed a similar overload resolution later, and happily picked the invalid specialization to call... resulting in a silent link failure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141809 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-12Add returns_twice to functions that are known to return twice. This implementsRafael Espindola

2011-10-12constexpr: don't consider class types with mutable members to be literal types.Richard Smith
The standard doesn't allow this, but mutable constexpr variables break the semantics so badly that we can't reasonably accept them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141768 91177308-0d34-0410-b5e6-96231b3b80d8

To prevent significant regression for should-this-be-a-call fixits, and to repair some such regression from the introduction of bound member placeholders, make those placeholder checks try to build calls appropriately.

2011-10-11Add typo correction for type names.Kaelyn Uhrain
The main motivation was to do typo correction in C++ "new" statements, though picking it up in other places where type names are expected was pretty much a freebie. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141621 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-10Constant expression evaluation refactoring:Richard Smith
- Remodel Expr::EvaluateAsInt to behave like the other EvaluateAs* functions, and add Expr::EvaluateKnownConstInt to capture the current fold-or-assert behaviour. - Factor out evaluation of bitfield bit widths. - Fix a few places which would evaluate an expression twice: once to determine whether it is a constant expression, then again to get the value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141561 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-10constexpr: Disable checking of constructor member initializer lists forRichard Smith
constexpr constructor templates. Such checking is optional, and currently hard to get right since clang doesn't generate implicit member initializers until instantiation (even for non-dependent members). This is needed for clang to accept libstdc++ from g++4.6 in c++0x mode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141547 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-10When adding a direct initializer to a declaration, allow theDouglas Gregor
initializer to update the type of the declaration. For example, this allows us to determine the size of an incomplete array from its initializer. Fixes PR10288. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141543 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-10Begin work consolidating ShouldDelete* functions.Sean Hunt
Begin with just default constructors. One note is that as a side effect of this, a conformance test was removed on the basis that this is almost certainly a defect as with most of union initialization. As it is, clang does not implement union initialization close to the standard as it's quite broken as written. I hope to write a paper addressing the issues eventually. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141528 91177308-0d34-0410-b5e6-96231b3b80d8
