| // Module Overview: Starboard Thread Types module |
| // |
| // Defines platform-specific threading and synchronization primitive types and |
| // initializers. We hide, but pass through, the platform's primitives to avoid |
| // doing a lot of work to replicate initialization-less synchronization |
| // primitives. |
| |
| // TODO: Implement a cross-platform initless synchronization model, and |
| // then properly hide thread primitives. This could look like implementing our |
| // own high-performance init-less lock (e.g. MCS or CLH) using the Atomics |
| // abstraction, and use that on all platforms and hope really hard that we |
| // didn't mess it up and then use that to auto-init uninitialized static |
| // objects. |
