Contains functions preventing some compiler optimisations, namely dead code removal. This is useful for benchmarking purposes.
primitive val DoNotOptimise
new val create() : DoNotOptimise val^
Prevent the compiler from optimising out obj and any computation it is derived from. This doesn't prevent constant propagation.
fun box apply[A: A]( obj: A) : None val
Prevent the compiler from optimising out writes to an object marked by the apply function.
fun box observe() : None val
fun box eq( that: DoNotOptimise val) : Bool val
fun box ne( that: DoNotOptimise val) : Bool val
