Move dont_need into MVP? · Issue #384 · WebAssembly/design (original) (raw)

Weighing costs/benefits, I was thinking there's little reason not to bump dont_need into the MVP: it's trivial to implement (if you don't want to do the implied sycall, you can just memzero), it'd be immediately used by the toolchain's malloc, and it would be immediately useful on mobile for reducing RSS and thus probability of oom-kill.
