I would keep the original logic of storing the result of loads.

Wouldn't this require then memory barriers to be added?, moving the store outside of the critical loop seems to work, but without a memory barrier it might get reordered and would cause failures (although not as obvious, as the infinite loop)

When refactoring, I thought about using a second array for the stores, but with a possible granule of 512 words, it will need ugly tricks to keep it safe anyway.

On ARM the doc says in "Load-Acquire, Store-Release" section:

  • A Load-Acquire places no additional ordering constraints on any loads or stores appearing before the
    Load-Acquire.
  • The Store-Release places no additional ordering constraints on any loads or stores appearing after the
    Store-Release instruction.

If barriers needs to be added on some cpus, the instruction should implicitly add them.

Note that (even before LSE and other future improvements) in aarch64 there are 2 pairs of instructions for its LL/SC.

Our implementation uses the weak (and better performing) pair of ldxr/stxr but their semantics don't correspond to what is used on other processors and that seem to map[1] better to the strong (and slower) pair (ldaxr/stlxr).

Not that anyone should, but if someone would implement a futex or mutex with sljit, it might work fine in x86/s390x and break with ARM (and probably the other RISC CPUs if implemented using LL/SC).

I have to admit that without a clear understanding on how this API is to be used, I am not sure if it is a problem but it might be something worth considering by maybe adding a "weak" parameter that would be a NOOP in strong ordered architectures and allow selecting the right pair in weak ordered ones like ARM.

If this is to be modeled like C11/C++11 atomics then maybe a full set of memory_order options might be needed instead.
