I need to implement the following loop-
float *a, *b;
int i, n;
...
for (i = 0; i < n; i++)
{

/* a is accessed with a variable stride( can be 4/5/6 ). */

/* b is accessed with a stride of 1. */
*( a+i ) = x + b[ i ];
a+= stride;

}
Any suggestions on how to load the array a?

I think as pointed out in your other post on this topic:

(1) you can't do this directly in NEON (for short strides you can use VLD2/3/4 and discard the bits you don't want but that isn't very efficient)
(2) generally it is inefficient, so you are better off restructuring your data, or unpacking the loop, so you don't need to.
