FPGA: Coercion dot for indices of small arrays?

[JKSH]

Say I have a 4-element, fixed size array. That means I only need 2 bits for the array index (00, 01, 10, 11). However, if I wire a U8 into the Index Array node, LabVIEW 2017 gives me a coercion dot because it's expecting an I32 index.

Does this coercion actually happen? Will my index be widened to 32-bits in the final compilation?

I don't know for sure but I think it is optimised away by the XIlinx compiler.
