This package provides various primitive memory-related operations.

Changes

Use more appropriate types in internal memset functions, which prevents overflows/segfaults on 64-bit systems.
Fixed a warning on GHC 7.10
Worked around a -dcore-lint bug in GHC 7.6/7.7

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

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

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

Add strict variants of MutVar modification functions atomicModifyMutVar' and modifyMutVar'
Fix compilation on Solaris 10 with GNU C 3.4.3

Support for GHC 7.2 array copying primitives
