For example, an operand might be at address `0x6BFFFF` with the high byte on `0x6BFFFF+1`.\r\nThey are handled in different ways.  `0x6BFFFF+1` could become `0x6B0000`, `0x6BFF00`, or carry into the bank (6B): `0x6C0000`.\r\nBecause of how rare this cases is, it simply isn’t tested in most tests, so both `0x6B0000` and `0x6C0000` implementations pass and it is impossible to know which is correct.\r\n\r\nEither more tests need to be generated to be sure these edge cases are covered or some percentage of 10,000 tests should be biased toward (or guaranteed to be) these edges cases.","author":{"url":"https://github.com/L-Spiro","@type":"Person","name":"L-Spiro"},"datePublished":"2024-05-01T00:12:10.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/82/ProcessorTests/issues/82"}
