fitzgen opened PR #13718 from fitzgen:gc-object-stores-alias-regions to bytecodealliance:main:
The copying collector's fresh-object header initialization writes now use the canonical GC memflags (like the null collector), and the pre-interned funcref array-element store gets the GC-heap region, matching how those locations are read elsewhere.
Note: these missing regions could not result in miscompiles previously because regionless stores are treated as memory fences by alias analysis.
