* Start moving SkRasterPipeline stages to SkOpts.Gravatar Mike Klein2016-09-29
| | | | | | | | | | | | | | | | | | | | This lets them pick up runtime CPU specializations. Here I've plugged in SSE4.1. This is still one of the N prelude CLs to full 8-at-a-time AVX. I've moved the union of the stages used by SkRasterPipelineBench and SkRasterPipelineBlitter to SkOpts... they'll all be used by the blitter eventually. Picking up SSE4.1 specialization here (even still just 4 pixels at a time) is a significant speedup, especially to store_srgb(), so much that it's no longer really interesting to compare against the fused-but-default-instruction-set version in the bench. So that's gone now. That left the SkRasterPipeline unit test as the only other user of the EasyFn simplified interface to SkRasterPipeline. So I converted that back down to the bare-metal interface, and EasyFn and its friends became SkRasterPipeline_opts.h exclusive abbreviations (now called Kernel_Sk4f). This isn't really unexpected: SkXfermode also wanted to build up its own little abstractions, and once you build your own abstraction, the value of an additional EasyFn-like layer plummets to negative. For simplicity I've left the SkXfermode stages alone, except srcover() which was always part of the blitter. No particular reason except keeping the churn down while I hack. These _can_ be in SkOpts, but don't have to be until we go 8-at-a-time.

* *SkTCast<int*>(float*) -> memcpyGravatar Mike Klein2016-09-29
| | | | | | | | | | | | | | | In some build configurations (I think, GN, GCC 6, Debug) I get a warning that i is used unintialized. This likely has something to do with GCC correctly seeing that the SkTCast construction there is illegal aliasing, and perhaps thus "doesn't happen". Might be that if the SkTCast gets inlined, it decides its implementation is secretly kosher, and so Release builds don't see this. None of this happens with the GCCs we have on the bots... too old? Instead use memcpy() here, which is well defined to do what we intended.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a less generally applicable trick than I have previously hoped. The need to thread through contexts into each stage really means you can only include one context-dependent stage in each fused batch. We can still manually fuse these, of course, as you can see in SkRasterPipelineBench. It's just that we can't really write a generic compile-time template to do it except for context-free stages. And since we can't write a generic version, and I have only this one specific use case right now, I've kept it quite specific to that use case. This does work pretty well for this use case, though.

* Make GPU configs use kRGBA color type not kN32.Gravatar bsalomon2016-09-28
| | | | | | | | | This makes ES msaa contexts testable on systems where kN32 is compiled as kBGRA due to the fact that render buffers are not always supported for GL_BGRA with GL_EXT_texture_format_BGRA8888.

* Rearrange SkRasterPipeline scanline tail handling.Gravatar Mike Klein2016-09-28
| | | | | | | | | | | | | | | | | | | We used to step at a 4-pixel stride as long as possible, then run up to 3 times, one pixel at a time. Now replace those 1-at-a-time runs with a single tail stamp if there are 1-3 remaining pixels. This style is simply more efficient: e.g. we'll blend and lerp once for 3 pixels instead of 3 times. This should make short blits significantly more efficient. It's also more future-oriented... AVX+ on Intel and SVE on ARM support masked loads and stores, so we can do the entire tail in one direct step. This also makes it possible to re-arrange the code a bit to encapsulate each stage better. I think generally this code reads more clearly than the old code, but YMMV. I've arranged things so you write one function, but it's compiled into two specializations, one for tail=0 (Body) and one for tail>0 (Tail). It's pretty tidy. For now I've just burned a register to pass around tail. It's 2 bits now, maybe soon 3 with AVX, and capped at 4 for even the craziest new toys, so there are plenty of places we can pack it if we want to get clever.

* Revert of Tag checkerboard bitmaps as sRGB (patchset #1 id:1 of ↵Gravatar brianosman2016-09-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | https://codereview.chromium.org/2368933003/ ) Reason for revert: Regression on displacement GM when sRGB support is lacking.

* Added kSRGBLinear_Named color space, along with testsGravatar brianosman2016-09-27
| | | | | | | | | | | | Gradients (and other shaders) are going to end up serializing this particular color space very frequently, so we want a shorthand way of writing it out. I think it's also helpful to have a clearer way of creating it (vs. NewNamed(kSRGB_Named)->makeLinearGamma()).

* SkRasterPipeline: add last() and docs.Gravatar Mike Klein2016-09-27
| | | | | | | | | | | | | | | | | | | Today if you use the simple SK_RASTER_STAGE interface to build a pipeline, each stage you add calls into a next stage. The last stage you add calls into a special backstop stage JustReturn that, well, just returns, ending the pipeline. This adds last(), which cuts that last stage off the pipeline. Instead, the stage you add using last() returns directly, ending the pipeline itself without jumping into JustReturn. This reduces the overhead of using the pipelined version of SkRasterPipelineBench from ~25% to ~20% on my desktop. Also, add docs.
