2011-01-25Add -add-plugin flag, which runs plugins in addition to codegen.Nico Weber
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124227 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-25Add an attribute to forbid temporary instances of a type. This allows classJeffrey Yasskin
authors to write class __attribute__((forbid_temporaries)) Name { ... }; when they want to force users to name all variables of the type. This protects people from doing things like creating a scoped_lock that only lives for a single statement instead of an entire scope. The warning produced by this attribute can be disabled by -Wno-forbid-temporaries. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124217 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-25Fix the ranking of reference bindings during overload resolutionDouglas Gregor
(C++0x [over.ics.rank]p3) when one binding is an lvalue reference and the other is an rvalue reference that binds to an rvalue. In particular, we were using the predict "is an rvalue reference" rather than "is an rvalue reference that binds to an rvalue", which was incorrect in the one case where an rvalue reference can bind to an lvalue: function references. This particular issue cropped up with std::forward, where Clang was picking an std::forward overload while forwarding an (lvalue) reference to a function. However (and unfortunately!), the right answer for this code is that the call to std::forward is ambiguous. Clang now gets that right, but we need to revisit the std::forward implementation in libc++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124216 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-25Be a bit more defensive about setting the temporary base locationDouglas Gregor
during template instantiation. This code needs to eventually die, but this little tweak fixes PR8629, where bad location information slipped through to the location of a class template instantiation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124199 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-25[analyzer] Handle the dot syntax for properties in the ExprEngine.Argyrios Kyrtzidis
We translate property accesses to obj-c messages by simulating "loads" or "stores" to properties using a pseudo-location SVal kind (ObjCPropRef). Checkers can now reason about obj-c messages for both explicit message expressions and implicit messages due to property accesses. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124161 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-24Re-instate r123977/r123978, my updates of the reference-bindingDouglas Gregor
implementation used by overload resolution to support rvalue references. The original commits caused PR9026 and some hard-to-reproduce self-host breakage. The only (crucial!) difference between this commit and the previous commits is that we now properly check the SuppressUserConversions flag before attempting to perform a second user-defined conversion in reference binding, breaking the infinite recursion chain of user-defined conversions. Rvalue references should be working a bit better now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124121 91177308-0d34-0410-b5e6-96231b3b80d8
