Looks like the filetest added in the earlier change to the store side needs to be updated (just changing movslq -> movq should be enough I think). |

PR 2840 changed the store_spillslot routine to always store integer registers in full word size to a spill slot. However, the load_spillslot routine was not updated, which may causes the contents to be reloaded in a different type. On big-endian systems this will fetch wrong data. Fixed by using the same type override in load_spillslot.
Indeed, looks like this fixed it. |
