This macro handles automatic differentiation. Automatic Differentiation macro which allows generating a new function to compute the derivative of a given function. It may only be applied to a function. The expected usage syntax is `#[autodiff(NAME, MODE, INPUT_ACTIVITIES, OUTPUT_ACTIVITY)]` where: NAME is a string that represents a valid function name. MODE is any of Forward, Reverse, ForwardFirst, ReverseFirst. INPUT_ACTIVITIES consists of one valid activity for each input parameter. OUTPUT_ACTIVITY must not be set if we implicitly return nothing (or explicitly return `-> ()`). Otherwise it must be set to one of the allowed activities.

Creates an array of type [T; N], where each element `T` is the returned value from `cb` using that element’s index.

Allocates zero-initialized memory with the global allocator.

Checks if `arm` feature is enabled.
