--- Comment #3 from Richard Earnshaw <rearnsha at gcc dot gnu.org> --- I think we should error if the name matches some iteration values, but not others. If <foo> is valid in the assembler output 'as-is' then it's bad form to have an attribute that overloads this - and the fix is easy: rename the iterator attribute.
