The one question you are bound to ask shortly is why we use ReversedPackedStrings, rather than PackedStrings in some cases - and the answer to that is there is no good reason. In the work if you fix all the cases where we have Reversed strings to normal strings that would be great!
Though I can't recommend trying! Packed strings appear all over the compiler, sometimes reversed, sometimes not, intermixed with code that either assumes 'reversed-ness' or doesn't. It would be seriously hard work to change :-)
Well I think I've run into this problem...maybe. All but one of the tests pass, the one that doesn't is the timeLargeArray test, and it fails with this error yhc: superclassesI InfoUsed (Id 68) [(Type class,Ord,"Data.Ix ",510:8-510:10)] Now my main question is how some PackedStrings can be reversed and others not when it looks like everything that uses PackedString imports it from SysDeps? The only exception I could find was compiler98/DotNet/Show.hs.
