This simplifies
SafeRefCount::ref
calls to always succeed, eliminating logic.In particular, this PR will speed up
RefCounted::init_ref
calls (nowreference
), e.g. improvingGDScript
function call overhead by ~4%.It should also slightly improve speed and reduce code of
reference
calls in general.Caveats
This commit introduces an edge case where the 2^32th reference will result in rollover, accidentally deallocating the object in question early.
It is unlikely this edge case is ever triggered for a real scenario, because 2^32 references would be 32GB of packed references (â 8 bytes), which is obviously nuts.
