iterate_over_pack()

template<class F , unsigned int N, bool SIMD = false>

YAKL_INLINE void yakl::simd::iterate_over_pack	(	F const &	f,
		PackIterConfig< N, SIMD >	config
	)

Perform a loop over the number of elements specified by the PackIterConfig object.

If the config parameter also specifies that the SIMD template parameter is true, then apply SIMD pragmas. IMPORTANT: For the functor passed to this routine, please use [&] syntax, not YAKL_LAMBDA

Parameters

f	The functor object to execute inside the loop.
config	yakl::PackIterConfig object with two template parameters: (1) the vector length (number of elements to loop over; and (2) a bool SIMD parameter to tell this routine whether or not it should apply a SIMD pragma.
