AlwaysSeqCst.jl provides macros @atomic, @atomicswap, and @atomicreplace that ignore the ordering arguments and use :sequentially_consistent always. It may be useful for a quick debugging of miss-specified memory orderings.

At the beginning of the module you are debugging:

using AlwaysSeqCst: @atomic, @atomicswap, @atomicreplace

Alternatively, to ignore the warning from the package loader:

const AlwaysSeqCst =
    Base.require(Base.PkgId(Base.UUID(0x2a0a5ff3012c40a8861a42ef8f4dfa06), "AlwaysSeqCst"))
using .AlwaysSeqCst: @atomic, @atomicswap, @atomicreplace
