* namespace {} trick for SK_DECLARE_STATIC_ONCEGravatar mtklein2015-01-13
| | | | | | | | | | | | | | | Like all our other SK_DECLARE_STATIC_*, it's usually not a thread-safe thing to put inside a function. Adding namespace {} prevents that syntactically. Needs https://codereview.chromium.org/841263004/ to land first. BUG=chromium:447890 No public API changes. TBR=reed@google.com Review URL: https://codereview.chromium.org/806473006
* Clean up SkOnce:Gravatar mtklein2014-06-02
| | | | | | | | | | | | | | | | 1 Remove atExit feature: clients can do it just as well as SkOnce can. 2 Remove support for functors: no one but the unit test did that. 3 Remove support for unused non-static SkOnceFlag (no SK_ONCE_INIT). 4 Add SkOnce variants for no-arg functions so we're not forced to pass dummy values all the time. 5 Merge SkSpinlock and SkOnceFlag, making all members private. 6 More notes about memory barriers, adding an acquire load after acquiring the spinlock.

| | | | | | | | | | | | | | This completes a TODO we've had to move our memory-barrier code out of SkOnce. I also want to start using sk_acquire_load elsewhere.

* ARM Skia NEON patches - 35 - First AArch64 supportGravatar commit-bot@chromium.org2014-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Aarch64 support This change contains the necessary modifications to have Skia build and run properly on an ARMv8 processor in aarch64 execution state. Here's a list of the changes: - add an arm64 target to the build system + SK_CPU_ARM64 flag - MatrixTest was failing when built in Release mode. Fused MAC instructions were generated which made some intermediate results more accurate. As the test relies on result comparison, the more precise results when compared to others led to a gap bigger than what was tolerated. As I don't know if some actual skia code relies on results being comparable, I've disabled fused MAC instruction with -ffp-contract=off for arm64. - Modify include/core/SkOnce.h to have barriers work. - SK_CPU_ARM64 implies SK_ARM_NEON_MODE_ALWAYS. - use existing Xfermode optimisations with modifications that can be removed in the future when toolchains are ready. Also save a few instructions is two Xfermodes (will apply to ARM too). - use existing SkBoxBlur and SkMorphology optimisations. - use existing SkBlitMask optimisations - use existing BitmapProcState and Convolution optimisations. Future changes will include: - Blitters (only partialy merged upstream) - SkUtils (there's little value in sending asm optimisations without having them benchmarked on real hardware).

* Make leak counters thread-safe and turn them on by default for DebugGravatar commit-bot@chromium.org2014-01-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make leak counters implemented with SK_DECLARE_INST_COUNT thread-safe. Enable the leak counting for Debug builds when Skia is built as a static library. Having SK_DECLARE_INST_COUNT without SK_DEFINE_INST_COUNT relies on static variables in member functions declared in the header files. These might be duplicated in the clients of the library when Skia is built as a dynamic library, producing incorrect operation. Protect the instance counter initialization step (initStep) by using SkOnce. Makes SkOnce.h part of the public API, since SkInstCnt is public. Protect the per-class child list shared variable with a per-class mutex. Changes the behavior in the way that if the child list has been "cleaned up", it will still try to create subsequent child lists.
