Detailed Description

When the front-end emits gathers and scatters, it generates an array of vector-width pointers to represent the set of addresses to read from or write to. This optimization detects cases when the base pointer is a uniform pointer or when the indexing is into an array that can be converted into scatters/gathers from a single base pointer and an array of offsets.

See for example the comments discussing the __pseudo_gather functions in builtins.cpp for more information about this.
