Summary: Fast Splittable PRNG

Pure Haskell implementation of SplitMix described in

Guy L. Steele, Jr., Doug Lea, and Christine H. Flood. 2014. Fast splittable
pseudorandom number generators. In Proceedings of the 2014 ACM International
Conference on Object Oriented Programming Systems Languages & Applications
(OOPSLA '14). ACM, New York, NY, USA, 453-472. DOI:
<https://doi.org/10.1145/2660193.2660195>

The paper describes a new algorithm /SplitMix/ for /splittable/ pseudorandom
number generator that is quite fast: 9 64 bit arithmetic/logical operations per
64 bits generated.

/SplitMix/ is tested with two standard statistical test suites (DieHarder and
TestU01, this implementation only using the former) and it appears to be
adequate for "everyday" use, such as Monte Carlo algorithms and randomized data
structures where speed is important.

In particular, it __should not be used for cryptographic or security
applications__, because generated sequences of pseudorandom values are too
predictable (the mixing functions are easily inverted, and two successive
outputs suffice to reconstruct the internal state).

* Mon Nov 01 2021 psimons@suse.com
  - Update splitmix to version 0.1.0.4.
    [#] 0.1.0.4
    - Add TestU01 test-suite
* Thu Dec 17 2020 Ondřej Súkup <mimi.vx@gmail.com>
  - disable %{ix86} build
* Fri Oct 23 2020 psimons@suse.com
  - Update splitmix to version 0.1.0.3.
    [#] 0.1.0.3
    - Fix oops bugs in 0.1.0.2
    - It's lowercase `windows.h`.
      I blame Microsoft docs for using capital case `Windows.h` in the docs.
      https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-getprocessid
    - accidental `shiftL` vs `shiftR` mixup for 32-bit generator initialization.
      Doesn't affect Linux.
* Tue Oct 20 2020 psimons@suse.com
  - Update splitmix to version 0.1.0.2.
    [#] 0.1.0.2
    - Drop `time` dependency in favour of handcoded initialization
    - On Unix platforms we use `/dev/urandom` if it exists,
      otherwise use `gettimeofday`, `clock` and `getpid`.
    - On Windows we use `GetCurrentProcessID`, `GetCurrentThreadId()`,
      `GetTickCount`, `GetSystemTime` and `QueryPerformanceCounter`.
    - On GHCJS use `Math.random()`
    - Using `time` is a fallback option (e.g. for Hugs).
* Tue Aug 18 2020 Peter Simons <psimons@suse.com>
  - Replace %setup -q with the more modern %autosetup macro.
* Fri Aug 07 2020 psimons@suse.com
  - Update splitmix to version 0.1.0.1.
    [#] 0.1.0.1
    - Add `INLINEABLE` pragmas to `bitmaskWithRejection*` functions
    - Support GHC-9.0
* Tue Jul 07 2020 psimons@suse.com
  - Update splitmix to version 0.1.
    [#] 0.1
    - Drop `random` dependency unconditionally.

* Tue Jun 09 2020 psimons@suse.com
  - Update splitmix to version 0.0.5.
    - Add `nextInteger`
    - Use smaller range in `bitmaskWithRejection32` and `64`, when
      upper bound is 2^n - 1. This changes generated values when they
      were on the boundary.
* Thu Feb 27 2020 psimons@suse.com
  - Update splitmix to version 0.0.4.
    - Add `bitmaskWithRejection32'` and `bitmaskWithRejection64'`
      which generate numbers in closed range `[0, n]`.
    - Unticked variants generate in closed-open range `[0, n)`.
* Fri Nov 08 2019 Peter Simons <psimons@suse.com>
  - Drop obsolete group attributes.
* Wed Jul 31 2019 psimons@suse.com
  - Update splitmix to version 0.0.3.
    - Add `System.Random.SplitMix32` module
    - Add `bitmaskWithRejection32` and `bitmaskWithRejection64` module
    - Add `nextWord32`, `nextTwoWord32` and `nextFloat`
    - Add `random` flag, dropping dependency on `random`
      (breaks things, e.g. `QuickCheck`, when disabled).
* Thu Mar 28 2019 psimons@suse.com
  - Add splitmix at version 0.0.2.
