This is herdtools7, a tool suite to test weak memory models.

We provide the following tools:

  • herd7: a generic simulator for weak memory models
  • litmus7: run litmus tests (given as assembler programs for Power, ARM, AArch64 or X86) to test the memory model of the executing machine
  • diy7: produce litmus tests from concise specifications
  • some additional tools In particular,
    • mcompare7 to analyse run logs of both herd and litmus.
    • klitmus7, an experimental tool, similar to litmus7 that runs kernel memory model tests as kernel modules. The tool klitmus7 is inspired from a python script by Andrea Parri,. http://retis.sssup.it/~a.parri/lkmm/run.py

herdtools7 is the successor of the diy tool suite.
