Interleaved access in GCC vectorization

["Jaishri" <jaishri@xxxxxxxxxxxxxx>]

Hi,
while studying non-unit stride access from paper "Auto-vectorization of
Interleaved Data for SIMD" by Dorit Nuzman, Ira Rosen, Ayal Zaks, I found
that these functions are not in latest release of GCC (GCC-4.2.3). If so
then when will they be included?
any pointer regarding this will be of great use for me.
Thanks in advance.
