Initialization

Overview

Initialization intrinsics for accumulator and vector types.

The "undef" functions are used to create a vector variable without the compiler giving a "using undefined variable" warning.

The "null" functions return a vector object of the given type with all of its values set to 0, and can be used to zero out a vector variable.

Null vectors

Returns a vector with all values set to 0.
