Sorry, IS superfluous (i.e. NOT needed).

Another nit-pick: http://llvm.org/viewvc/llvm-project/cfe/trunk/include/clang/Sema/Sema.h?r1=148254&r2=148253&pathrev=148254

+  QualType GetSignedVectorType(QualType V);
   QualType CheckVectorCompareOperands(ExprResult &LHS, ExprResult &RHS,
                                       SourceLocation Loc, bool isRelational);
+  QualType CheckVectorLogicalOperands(ExprResult LHS, ExprResult RHS,
+                                      SourceLocation Loc);

I can't check this at the moment, but is there any reason why CheckVectorLogicalOperands can't receive its parameters by reference?

Thanks,
Anton.

Hi Tanya,

Eli has also noticed that 'else if' should have been on the previous line.

The first comment line is not superfluous.

Could you please also add the test below?

Many thanks,
Anton.
