[PATCH] D141189: [Mips] Set setMaxAtomicSizeInBitsSupported

[Davide Mor via Phabricator via llvm-commits]

Yes exactly, what I'm saying is that if we just emit sync fences (in the form of libcalls) for CAS/RMW operations it might become impossible to target systems that have some sort of preemption. So I personally would prefer to set atomic width to 0 and generate libcalls for all atomic operations, so implementors for specific environments can do the right thing for the platform.
