To match Ibex behaviour this updates the spike unaligned load/store behaviour to try accessing all bytes rather than stopping as soon as an error is seen. If one or more errors are seen whilst accessing these bytes the first one is thrown.

I think we'll hold off on merging this for now, we also need changes on the co-sim side for it to work and some more investigation is needed there lowRISC/ibex#1948 |

I tried applying these changes myself and ran into the same issue, are there any updates on this that allow spike to continue running after an exception? |
