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.

Which functions are lacking/missing?
The ones mentioned in the paper should be in GCC 4.1, and (I presume) later.
Are you specifying the GCC flags that enable the desired SIMD hardware
capability on your platform?
Sincerely,

Vectorization of interleaved data is implemented in GCC 4.3.
