Function Documentation

CalculateNumChildren()

static std::optional< size_t > CalculateNumChildren ( CompilerType  container_elem_type, uint64_t  num_elements, CompilerType  element_type  )

static

Calculates the number of elements stored in a container (with element type 'container_elem_type') as if it had elements of type 'element_type'.

For example, a container of type uint8_t __attribute__((vector_size(16))) has 16 elements. But calling CalculateNumChildren with an 'element_type' of float (4-bytes) will return 4 because we are interpreting the byte-array as a float32[].

Parameters

[in]	container_elem_type	The type of the elements stored in the container we are calculating the children of.
[in]	num_elements	Number of 'container_elem_type's our container stores.
[in]	element_type	The type of elements we interpret container_type to contain for the purposes of calculating the number of children.

Returns

The number of elements stored in a container of type 'element_type'. Returns a std::nullopt if the size of the container is not a multiple of 'element_type' or if an error occurs.
