* SkOnce in is_lcd_supported instead of hand rolled double-checked locking.Gravatar commit-bot@chromium.org2014-02-10

* 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.

* Guard against most unintentionally ephemeral SkAutoFoo instantiations.Gravatar commit-bot@chromium.org2013-11-18
| | | | | | | | | | | | | | | | | | | I think I applied the trick everywhere possible. Limitations: - can't be used with templated classes - all constructors and destructors must be defined inline A couple of the SkAutoFoo were unused in Skia, Chromium, and Android, so I deleted them. This change caught the same bugs Cary found in SkPath, plus one more in SampleApp. BUG= R=reed@google.com, caryclark@google.com Author: mtklein@google.com Review URL: https://codereview.chromium.org/72603005 git-svn-id: http://skia.googlecode.com/svn/trunk@12301 2bbb7eff-a529-9590-31e7-b0007b416f81

* posix: Avoid static initializers in static/global mutexesGravatar digit@google.com2012-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes static initializers related to static and global mutexes from the final library's machine code when building on a pthread-capable system. We use PTHREAD_MUTEX_INITIALIZER to perform POD-style initialization. You need a line like the following to declare a global mutex with it: SkBaseMutex gMutex = { PTHREAD_MUTEX_INITIALIZER }; We introduce the SK_DECLARE_STATIC_MUTEX and SK_DECLARE_GLOBAL_MUTEX macros to be able to declare static/global mutexes in the source tree uniformly. SkMutex is now defined as a sub-class of SkBaseMutex, with standard construction/destruction semantics. This is useful if the mutex object is a member of another C++ class, or allocated dynamically. We also modify a few places to refer to SkBaseMutex instead of a SkMutex, where it makes sense. Generally speaking, client code should hold and use pointers to SkBaseMutex whenever they can now. We defined a new built-time macro named SK_USE_POSIX_THREADS to indicate that we're using a pthread-based SkThread.h interface. The macro will also be used in future patches to implement other helper thread synchronization classes. Finally, we inline the acquire() and release() functions in the case of Posix to improve performance a bit.
