Spin Loop Hint support: Draft JEP proposal (original) (raw)

I wonder how Gil's proposed PerformanceHints.spinLoopHint() is to be called. Just before entering the spin-loop or at each iteration of the loop?

The latter, e.g. see the benchmark code.

Is this some kind of CPU.yield() (by analogy to Thread.yield())?

I was wondering the same, it feels like a more vague (API abstraction-wise at least) architecture specific Thread.yield().
