[Bug middle-end/29779] New: vectorizer fortran testcases failing

[dorit at il dot ibm dot com]

Looks like sometime between Oct27 
(http://gcc.gnu.org/ml/gcc-testresults/2006-10/msg01336.html) 
and Oct30 
(http://gcc.gnu.org/ml/gcc-testresults/2006-10/msg01538.html) 
the fortran vectorizer testcases started ICEing on:

gfortran.dg/vect/vect-3.f90:0: warning: 'const' attribute directive ignored
gfortran.dg/vect/vect-3.f90:4: internal compiler error: in
vect_setup_realignment, at tree-vect-transform.c:2534

Should be related somehow to this code in rs6000.c:

      /* Initialize target builtin that implements
         targetm.vectorize.builtin_mask_for_load.  */

      decl = add_builtin_function ("__builtin_altivec_mask_for_load",
                                   v16qi_ftype_long_pcvoid,
                                   ALTIVEC_BUILTIN_MASK_FOR_LOAD,
                                   BUILT_IN_MD, NULL,
                                   tree_cons (get_identifier ("const"),
                                              NULL_TREE, NULL_TREE));


Anybody knows which patch caused this?
