Workaround:
The only workaround is to insert a NOP intrinsic at the end or the beginning of the repeat block. However, one would have to first identify the latency violation.
Release Notes:

Hide
In the case of a special instruction sequence requiring an additional latency-- a 2-cycle floating point instruction followed by a trigonometric math instruction, the additional required cycle was not generated when the instructions appeared in a repeat block and the result of the floating point instruction was used in the next iteration of the repeat block.
