 This was fixed on mainline by the following patch, whose
 date is actually 2003-04-01:
 
 2003-02-31  Aldy Hernandez  <aldyh@redhat.com>
 
         * testsuite/gcc.c-torture/execute/simd-3.c: New.
 
         * expr.c (expand_expr): Handle VECTOR_CST.
           (const_vector_from_tree): New.
 
         * varasm.c (output_constant): Handle VECTOR_CST.
 
         * c-typeck.c (digest_init): Build a vector constant from a
           VECTOR_TYPE.
 
         [lots of changes to files in config/rs6000]
 
 My hunt used the testcase that Volker sent me yesterday
 and checked that the generated .s file did not include
 'mulps'.
