2010-04-12Implement C++ [temp.local]p4, which specifies how we eliminateDouglas Gregor
name-lookup ambiguities when there are multiple base classes that are all specializations of the same class template. This is part of a general cleanup for ambiguities in template-name lookup. Fixes PR6717. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101065 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-12When creating the implicitly-declared special member functions, beDouglas Gregor
sure to introduce them into the current Scope (when we have one) in addition to the DeclContext for the class, so that they can be found by name lookup for inline members of the class. Fixes PR6570. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101047 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-12Add another test case for r101029, which verifies that we nowDouglas Gregor
correctly diagnose instantiation of a function parameter with Objective-C class type (since Objective-C classes can't be passed by value). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101031 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Be sure to instantiate the parameters of a function, even when theDouglas Gregor
function's type is (strictly speaking) non-dependent. This ensures that, e.g., default function arguments get instantiated properly. And, since I couldn't resist, collapse the two implementations of function-parameter instantiation into calls to a single, new function (Sema::SubstParmVarDecl), since the two had nearly identical code (and each had bugs the other didn't!). More importantly, factored out the semantic analysis of a parameter declaration into Sema::CheckParameter, which is called both by Sema::ActOnParamDeclarator (when parameters are parsed) and when a parameter is instantiated. Previously, we were missing some Objective-C and address-space checks on instantiated function parameters. Fixes PR6733. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101029 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-11fix PR6811 by not parsing 'super' as a magic expression inChris Lattner
LookupInObjCMethod. Doing so allows all sorts of invalid code to slip through to codegen. This patch does not change the AST representation of super, though that would now be a natural thing to do since it can only be in the receiver position and in the base of a ObjCPropertyRefExpr. There are still several ugly areas handling super in the parser, but this is definitely a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100959 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-10Diagnose more cases of initializing distinct members of an anonymous unionJohn McCall
member. Use a better diagnostic for this case. Also fix a bug with nested anonymous structs/unions for -Wreorder; this last was PR6575. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100923 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-10Diagnose misordered initializers in constructor templates immediately instead ofJohn McCall
when they're instantiated. Merge the note into the -Wreorder warning; it doesn't really contribute much, and it was splitting a thought across diagnostics anyway. Don't crash in the parser when a constructor's initializers end in a comma and there's no body; the recovery here is still terrible, but anything's better than a crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100922 91177308-0d34-0410-b5e6-96231b3b80d8
