primitive

Changes in version 0.6

• Split PrimMonad into two classes to allow automatic lifting of primitive operations into monad transformers. The internal operation has moved to the PrimBase class.

• Fixed the test suite on older GHCs

Changes in version 0.5.4.0

• Changed primitive_ to work around an oddity with GHC’s code generation on certain versions that led to side effects not happening when used in conjunction with certain very unsafe IO performers.

• Allow primitive to build on GHC 7.9

Changes in version 0.5.3.0

• Implement cloneArray and cloneMutableArray primitives (with fall-back implementations for GHCs prior to version 7.2.1)

Changes in version 0.5.2.1

• Add strict variants of MutVar modification functions atomicModifyMutVar' and modifyMutVar'

• Fix compilation on Solaris 10 with GNU C 3.4.3

Changes in version 0.5.1.0

• Add support for GHC 7.7’s new primitive Bool representation

Changes in version 0.5.0.1

• Disable array copying primitives for GHC 7.6.* and earlier

Changes in version 0.5

• New in Data.Primitive.MutVar: atomicModifyMutVar

• Efficient block fill operations: setByteArray, setAddr

Changes in version 0.4.1

• New module Data.Primitive.MutVar

Changes in version 0.4.0.1

• Critical bug fix in fillByteArray

Changes in version 0.4

• Support for GHC 7.2 array copying primitives

• New in Data.Primitive.ByteArray: copyByteArray, copyMutableByteArray, moveByteArray, fillByteArray

• Deprecated in Data.Primitive.ByteArray: memcpyByteArray, memcpyByteArray', memmoveByteArray, memsetByteArray

• New in Data.Primitive.Array: copyArray, copyMutableByteArray

• New in Data.Primitive.Addr: copyAddr, moveAddr

• Deprecated in Data.Primitive.Addr: memcpyAddr
