For more details, see https://ghc.haskell.org/trac/ghc/wiki/Design/IntegerGmp2 ## 0.5.1.0 *Feb 2014* * Bundled with GHC 7.8.1 * Improved Haddock documentation * New [PrimBool](https://ghc.haskell.org/trac/ghc/wiki/PrimBool) versions of comparison predicates in `GHC.Integer`: eqInteger# :: Integer -> Integer -> Int# geInteger# :: Integer -> Integer -> Int# gtInteger# :: Integer -> Integer -> Int# leInteger# :: Integer -> Integer -> Int# ltInteger# :: Integer -> Integer -> Int# neqInteger# :: Integer -> Integer -> Int# * New `GHC.Integer.testBitInteger` primitive for use with `Data.Bits` * Reduce short-lived heap allocation and try to demote `J#` back to `S#` more aggressively. See also [#8647](https://ghc.haskell.org/trac/ghc/ticket/8647) for more details. * New GMP-specific binary (de)serialization primitives added to `GHC.Integer.GMP.Internals`: importIntegerFromByteArray importIntegerFromAddr exportIntegerToAddr exportIntegerToMutableByteArray sizeInBaseInteger * New GMP-implemented number-theoretic operations added to `GHC.Integer.GMP.Internals`: gcdExtInteger nextPrimeInteger testPrimeInteger powInteger powModInteger powModSecInteger recipModInteger
