Detailed Description

Reduces the range along with the initial value init over op.

Parameters

policy	Needs to be vir::execution::simd or one of the derived types returned from its modifiers. (vir::detail::simd_execution_policy)
first,last	Iterator pair modelling vir::detail::simd_execution_iterator.
rg	Input ranges modelling vir::detail::simd_execution_range.
op	Callable to be invoked with two simd objects of input elements or intermediate results.

Returns

The generalized sum of init (if given) and the elements of the input range over op / std::plus.
