2011-01-24Mark VTables and RTTI data linkonce_odr instead of weak_odr, with the ↵Anders Carlsson
exception of explicit template instantiations, which have to be weak_odr. This fixes PR6996. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124089 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-23Null initialize a few variables flagged byTed Kremenek
clang's -Wuninitialized-experimental warning. While these don't look like real bugs, clang's -Wuninitialized-experimental analysis is stricter than GCC's, and these fixes have the benefit of being general nice cleanups. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124072 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-21Provide -Wuninitialized-experimental fixitsTed Kremenek
for floats, and also check if 'nil' is declared when suggesting it for initializing ObjC pointers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124004 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-21When throwing an elidable object, first try to treat the subexpressionDouglas Gregor
as an rvalue per C++0x [class.copy]p33. If that fails, try again with the original subexpression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124002 91177308-0d34-0410-b5e6-96231b3b80d8

functionality change git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123996 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-21Add basic fixits for -Wuninitialized-experimentalTed Kremenek
to suggest initializations for pointer and ObjC pointer types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123995 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-21Enhance -Wuninitialized-experimental diagnosticsTed Kremenek
to issue the warning at an uninitialized variable's declaration, but to issue notes at possible uninitialized uses (which could be multiple). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123994 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-21Implement the preference for move-construction over copy-constructionDouglas Gregor
when returning an NRVO candidate expression. For example, this properly picks the move constructor when dealing with code such as MoveOnlyType f() { MoveOnlyType mot; return mot; } The previously-XFAIL'd rvalue-references test case now works, and has been moved into the appropriate paragraph-specific test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123992 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123983 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-21Promote the static getNRVOCandidate() function, which computed theDouglas Gregor
NRVO candidate for a return statement, to Sema::getCopyElisionCandidate(), and teach it enough to also determine the NRVO candidate for a throw expression. We still don't use the latter information, however. Along the way, implement core issue 1148, which eliminates copy elision from catch parameters and clarifies that copy elision cannot occur from function parameters (which we already implemented). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123982 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-21Implement core issue 1164, which concerns the partial ordering ofDouglas Gregor
f(T&) and f(T&&). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123981 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-21Add unique_ptr example to test the use of rvalue references. I'll growDouglas Gregor
this example further as more rvalue-reference features come online. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123980 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-21Add test for overload resolution's preference for binding an rvalueDouglas Gregor
reference to an rvalue rather than binding a const-qualified lvalue reference to that rvalue. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123979 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-21Update the reference-binding implementation used for overloadDouglas Gregor
resolution to match the latest C++0x working paper's semantics. The implementation now matching up with the reference-binding implementation used for initialization. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123977 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-21More testing to C++0x [temp.deduct.call]p3Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123967 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-21Implement the special template argument deduction rule for T&& in aDouglas Gregor
call (C++0x [temp.deduct.call]p3). As part of this, start improving the reference-binding implementation used in the computation of implicit conversion sequences (for overload resolution) to reflect C++0x semantics. It still needs more work and testing, of course. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123966 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-21Sema: process non-inheritable attributes on function declarations earlyPeter Collingbourne
