Creates a vector from unsigned integer values known at compile-time.
The values passed to this function are converted using standard conversions to the element type of the resulting vector. All conversions and other overhead is performed at compile-time thus even if the minimal optimization level is selected, the function results in a simple load from memory.
The function is not guaranteed to have adequate performance if the arguments are not known at compile-time.
If the vector has fewer elements than the number of the parameters this function accepts then the extra values are discarded.
The first set of overloads loads to given non-mask vector type.
The second set of overloads returns a value of unspecified type with which any non-mask vector can be initialized. E.g. int32<4> x = make_int(1, 2, 3, 4);
Parameters[edit]
v0, ..., v15 | - | the values to initialize the vector to |
Return value[edit]
(1) Vector that contains the given values.
(2) An value of unspecified type that can initialize a vector with the given values as if the first version of the function was executed.
