* Use a spinlock in SkOnce.Gravatar commit-bot@chromium.org2014-01-08
| | | | | | | | | | | | | | | | | SkOnceFlag is now statically initializable on all platforms. Also adds sk_atomic_cas, used to implement new SkSpinlock. Going to punt on making SkOnceFlag any smaller (for now, it's 8 bytes). We could conceivably get it down to two bits, one for done and one for a one-bit spinlock (we'd need atomic-& and atomic-| to make that work, but they appear to be available everywhere).

* Split atomic and mutex implementations and make inlinable.Gravatar bungeman@google.com2013-12-18
Skia cannot use Chromium's implementation of mutex (Lock) due to static initializers. However, we would like to be able to use Chromium's implementation of atomics. This motivates the split of implementation. Skia's atomic and mutex calls should be inlinable, especially the atomics. These calls often compile down to very few instructions, and we currently have the overhead of a function call. This motivates the header implementation. There is still a desire for the build system to select the implementation, so the SK_XXX_PLATFORM_H pattern for header files is introduced. This allows the build system to control which platform specific header files are chosen.
