I have seen the following warning on master for some time
compiler/GHC/Core/TyCon.hs:1540:5: warning:
• Ignoring unusable UNPACK pragma
on the first argument of ‘BoxedRep’
• In the definition of data constructor ‘BoxedRep’
In the data type declaration for ‘PrimRep’
|
1540 | | BoxedRep {-# UNPACK #-} !(Maybe Levity) -- ^ Boxed, heap value
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Is it something that needs to be fixed? Can the code be updated to remove
the warning?
Alan
