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.
