* optimize intersect, use getType to utilize fast-case in preTranslateGravatar Mike Reed2017-03-07
| | | | | | | | | | | | | | | 10-15% speed up in clip_record_overhead bench Comparing the raw fType field was missing the (maybe deprecatable) IsRectToRect bit (0x10), which is set for identity and translate matrices, so we were never taking the fast case.

| | | | | | | | | | | | | | | | | When checking whether a matrix was a pure scale, we subtracted 0x3f800000 from the diagonals; if the diagonal value was already very negative, we'd underflow. Replace subtraction with XOR. When dealing with repeating tiled bitmaps, when the bitmap was very large, we'd multiply an offset by 65535, possibly causing underflow. Throw in a cast to long (casting to unsigned also silences the warning and wouldn't involve extension, but I can't convince myself that it's correct).

| | | | | | | | | | | | | | | | | | | | | | No changes to the code, just moved around. This will have the effect of enabling vectorized code on ARMv7. Should be no effect on ARMv8 or x86, which would have been vectorized already. nanobench --match mappoints changes on Nexus 5 (ARMv7): _affine: 132 -> 95 _scale: 118 -> 47 _trans: 60 -> 37 A teaser: We should next look at the ABCD->BADC shuffle we've noted that we need in _affine. A quick hack showed doing that optimally is another ~35% speedup on x86. Got to figure out how to do it best on ARM though: that same quick hack was a 2x slowdown there. Good reason to resurrect that SkNx_shuffle() CL! (I believe the answers are vrev64q_f32(v) and _mm_shuffle_ps(v,v, _MM_SHUFFLE(2,3,0,1), but we should probably find out in another CL.)

* Remove SK_OFFSETOF from SkTypes, clean up offsetof usage.Gravatar bungeman2015-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The motivation for this was to remove SK_OFFSETOF from SkTypes, but this CL is mostly about cleaning up our use of offsetof generally. SK_OFFSETOF is removed to SkTypes and added to the two places it is actually used (for the non standard behavior of finding the offset of fields in types which are not standard layout). Older versions of gcc required POD for offsetof to be used without warning. Newer versions require the more relaxed standard layout. Now that we no longer build on older versions of gcc, remove the old warning suppressions. PODMatrix is renamed to AggregateMatrix. SkMatrix is already POD (trivial and standard layout). The PODMatrix name implies that the POD-ness is needed for the offsetof, but it is actually the aggregate attribute which is needed for compile time constant initialization. This makes it more obvious that this can be revisited after we can rely on constexpr constructors. This also adds skstd::declval since this allows removal of existing awkward code which casts a constant to a pointer to find the size of a field.

* Refactor Sk2x<T> + Sk4x<T> into SkNf<N,T> and SkNi<N,T>Gravatar mtklein2015-03-30
| | | | | | | | | | | | | | | | | | | | | The primary feature this delivers is SkNf and SkNd for arbitrary power-of-two N. Non-specialized types or types larger than 128 bits should now Just Work (and we can drop in a specialization to make them faster). Sk4s is now just a typedef for SkNf<4, SkScalar>; Sk4d is SkNf<4, double>, Sk2f SkNf<2, float>, etc. This also makes implementing new specializations easier and more encapsulated. We're now using template specialization, which means the specialized versions don't have to leak out so much from SkNx_sse.h and SkNx_neon.h. This design leaves us room to grow up, e.g to SkNf<8, SkScalar> == Sk8s, and to grown down too, to things like SkNi<8, uint16_t> == Sk8h. To simplify things, I've stripped away most APIs (swizzles, casts, reinterpret_casts) that no one's using yet. I will happily add them back if they seem useful. You shouldn't feel bad about using any of the typedef Sk4s, Sk4f, Sk4d, Sk2s, Sk2f, Sk2d, Sk4i, etc. Here's how you should feel: - Sk4f, Sk4s, Sk2d: feel awesome - Sk2f, Sk2s, Sk4d: feel pretty good No public API changes.
