Arguments
a
256-bit float64 source vector
b
128-bit float64 source vector
offset
an integer value that represents the 128-bit offset where the insertion must start
Description
Performs an insertion of 128 bits of packed double-precision floating-point values (float64 values) from the second source vector
b
into a destination at a 128-bit offset specified by the
offset
