vec_extract_even/odd are not implemented on ia64. They are used in
vectorization of strided loads, and are implemented only on powerpc (patch
http://gcc.gnu.org/ml/gcc-patches/2006-03/msg01679.html (revision 119088)).
The implementation exists on autovect-branch, but it possibly can be more
efficient (http://gcc.gnu.org/ml/gcc-patches/2006-09/msg01278.html):
2005-12-01 Richard Henderson <rth@redhat.com>
* targhooks.c (interleave_vectorize_builtin_extract_evenodd): New.
(interleave_vectorize_builtin_extract_even): New.
(interleave_vectorize_builtin_extract_odd): New.
* targhooks.h: Declare them.
* config/i386/i386.c (TARGET_VECTORIZE_BUILTIN_EXTRACT_EVEN): New.
(TARGET_VECTORIZE_BUILTIN_EXTRACT_ODD): New.
2005-12-02 Richard Henderson <rth@redhat.com>
* config/ia64/ia64.c (TARGET_VECTORIZE_BUILTIN_EXTRACT_EVEN): New.
(TARGET_VECTORIZE_BUILTIN_EXTRACT_ODD): New.
2006-09-28 Ira Rosen <irar@il.ibm.com>
* targhooks.c (interleave_vectorize_builtin_extract_evenodd):
Fix to produce a correct instructions sequence.
* tree-vect-transform.c (vect_permute_store_chain): Choose the
correct instruction according to the endianness. Call
mark_new_vars_to_rename.
Once the above is merged, we can add ia64 to the list of targets that support
check_effective_target_vect_extract_even_odd in
testsuite/lib/target-support.exp.
