Question on scalar replacement

    Do we get inside this if() statement in scalarize_call_expr()?

      /* If the LHS of the assignment is a scalarizable structure, insert
         copies into the scalar replacements after the call.  */
      if (is_sra_candidate_decl (var))

No.  That's what I was trying to say.  VAR is a COMPONENT_REF here.
