The bug was initially revealed by a randomly generated program of around 113 lines, which we were able to reduce to the minimal example shown in the figure. The program repeatedly shifts a large integer value \code{b} right by the values stored in array \code{a}. Vivado HLS returns \code{0x006535FF}, but the result returned by GCC (and subsequently confirmed manually to be the correct one) is \code{0x046535FF}. |
