NCG: Refactor representation of code with liveness info * I've pushed the SPILL and RELOAD instrs down into the LiveInstr type to make them easier to work with. * When the graph allocator does a spill cycle it now just re-annotates the LiveCmmTops instead of converting them to NatCmmTops and back. * This saves working out the SCCS again, and avoids rewriting the SPILL and RELOAD meta instructions into real machine instructions.

make some Applicative functions into methods, and split off Data.Functor (proposal #3335) The following functions (<$) :: Functor f => a -> f b -> f a (*>) :: Applicative f => f a -> f b -> f b (<*) :: Applicative f => f a -> f b -> f a some :: Alternative f => f a -> f [a] many :: Alternative f => f a -> f [a] are moved into the corresponding classes, with the existing implementations as default definitions. This gives people creating instances the option of defining specialized implementations of these functions, though they should be equivalent to the default definitions. Although (<$) is now a method of the Functor class, it is hidden in the re-export by the Prelude, Control.Monad and Monad. The new module Data.Functor exposes the full class, plus the function (<$>). These are also re-exported by Control.Applicative.

make some Applicative functions into methods, and split off Data.Functor (proposal #3335) The following functions (<$) :: Functor f => a -> f b -> f a (*>) :: Applicative f => f a -> f b -> f b (<*) :: Applicative f => f a -> f b -> f a some :: Alternative f => f a -> f [a] many :: Alternative f => f a -> f [a] are moved into the corresponding classes, with the existing implementations as default definitions. This gives people creating instances the option of defining specialized implementations of these functions, though they should be equivalent to the default definitions. Although (<$) is now a method of the Functor class, it is hidden in the re-export by the Prelude, Control.Monad and Monad. The new module Data.Functor exposes the full class, plus the function (<$>). These are also re-exported by Control.Applicative.

Put context information for warnings in errMsgExtraInfo. For type checker warnings, the context information ("In the expression ...") was simply appended to the main message while for proper errors they live in errMsgExtraInfo. This allows GHC API clients to drop that information if not needed.

On Windows, use the console code page for text file encoding/decoding. We keep all of the code page tables in the module GHC.IO.Encoding.CodePage.Table. That file was generated automatically by running codepages/MakeTable.hs; more details are in the comments at the start of that script. Storing the lookup tables adds about 40KB to each statically linked executable; this only increases the size of a "hello world" program by about 7%. Currently we do not support double-byte encodings (Chinese/Japanese/Korean), since including those codepages would increase the table size to 400KB. It will be straightforward to implement them once the work on library DLLs is finished.
