    Syntax:
    + +
    +  <result> = insertelement <n x <ty>> <val>, <ty> <elt>, uint <idx>    ; yields <n x <ty>>
+
    + +
    Overview:
    + +

    +The 'insertelement' instruction inserts a scalar +element into a packed vector at a specified index. +

    + + +
    Arguments:
    + +

    +The first operand of an 'insertelement' instruction is a +value of packed type. The second operand is a +scalar value whose type must equal the element type of the first +operand. The third operand is an index indicating the position at +which to insert the value. The index may be a variable.

    + +
    Semantics:
    + +

    +The result is a packed vector of the same type as val. Its +element values are those of val except at position +idx, where it gets the value elt. If idx +exceeds the length of val, the results are undefined. +

    + +
    Example:
    + +
    +  %result = insertelement <4 x int> %vec, int 1, uint 0    ; yields <4 x int>
