A recent discussion raises up the requirement for having test cases for atomic APIs:
https://lore.kernel.org/lkml/20200213085849.GL14897@hirez.programming.kicks-ass.net/
, and since we already have a way to generate a test module from a litmus test with klitmus[1]. It makes sense that we add more litmus tests for atomic APIs into memory-model.
So I begin to do this and the plan is to add the litmus tests we already use in atomic_t.txt, ones from Paul's litmus collection[2], and any other valuable litmus test we come up while adding the previous two kinds of tests.
This patchset finishes the first part (adding atomic_t.txt litmus tests). I also improve the atomic_t.txt to make it consistent with the litmus tests.
One thing to note is patch #2 requires a modification to herd and I just made a PR to Luc's repo:
https://github.com/herd/herdtools7/pull/28
, so if this patchset looks good to everyone and someone plans to take it (and I assume is Paul), please wait until that PR is settled. And probably we need to bump the required herd version because of it.
Comments and suggesions are welcome!
Regards, Boqun
