* with no more offline codegen, seed_shader can be normalGravatar Mike Klein2018-03-11
| | | | | | | | | | | | | | We passed this iota array as an argument before because it was generating awkward code for our object file parser to handle (relocations, other weird things, can't quite remember). Now that we're compiling pipeline code normally, we can make seed_shader a normal stage again, with no special iota ctx pointer needed.

| | | | | | | | | | | | | | Should give dramatically better codegen for all 32-bit builds and 64-bit Windows builds, bringing it in line with how we make highp float stages. May help this bug, which is mostly Windows perf regressions.

The two are usually the same, except when we opt Clang builds into JUMPER_IS_SCALAR artificially. Some Google3 builds use compilers old enough that they barf when compiling our NEON code. It's conceivably also possible to define JUMPER_IS_SCALAR yourself, but I don't think anyone does that.

* make SkOpts functions inline, not staticGravatar Mike Klein2017-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | When Skia's built with an interestingly advanced instruction set baseline like SSSE3 or SSE4.1, we end up with two distinct copies of some SkOpts functions, one default in SkOpts.o and one specialization from SkOpts_{ssse3,sse41}.o. These functions are static, and so are technically unrelated, even though they're the same code compiled with the same instructions available. They're going to be identical. What we want here is to remove static but mark them as inline instead. In this case inline means "if the linker sees multiple copies of this, that's cool, just pick any one arbitrarily". That's just what we want. Now, when I disassemble a binary before and after this change, I do see the redundant routines removed. However, the file size change is minimal... I suspect that this must mean the linker has noticed that we had identical code and physically folded the two logically independent routines. I don't know how prevalent this optimization is, though, so it doesn't hurt to give it more of a "one copy please" hint with inline. There may also be a difference here between the binary size (~unchanged) and the in-memory layout of that binary?

Pretty exciting.

* Retry cleaning up SkLinearBitmapPipeline.Gravatar Mike Klein2017-07-20
| | | | | | | | | | | | | | | | | | This is mostly dead code. In order to make it truly dead, we need to opt drawing unpremul images into SkRasterPipelineBlitter. They had been handled by SkLinearBitmapPipeline, but can't be draw by SkBitmapProcLegacyShader. Drawing unpremul images is tested by the GM all_variants_8888, which gave us trouble last time around (serialize-8888 drew right, 8888 wrong) but now draws fine. I think this was probably also the root of the revert, drawing some unpremul image in Chrome's tests somewhere.

* Faster and more accurate blit_row_s32a_opaque for ARMGravatar Matteo Franchin2017-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change ARM implementation of alpha blending to work on 8 pixels at a time (using NEON). Also improve the accuracy of alpha blending by using a formula based on SkMulDiv255Round rather than SkPMSrcOver. Note that a number of variations of this code were considered. Here are some notes: - A 16 pixels at a time version was considered. This performs well for the case of extreme alpha (all-opaque or all-transparent pixels), but performs worst than the 8 pixels version when there are frequent transitions of alpha. Also gcc 6.2.1 seems to have troubles with register pressure when using this version. - If the branch to detect the fully-opaque or fully-transparent cases is removed, then the performance increases significantly for images which are all partially transparent (especially on ARM Cortex A72), but can significantly decrease for images that are almost fully opaque or fully transparent. This implementation is a compromise to the effects described above. This patch produces a ~10% improvement on the nanobench's sub-scores repeatTile_BGRA_8888_A, constXTile_MM_filter_trans, constXTile_CC_trans, constXTile_RR_filter_trans when running on ARM Cortex A72. Improvements of greater magnitude (20% to 30%) are observed when running on ARM Cortex A53.

* jumper, rework callback a bit, use it for color_lookup_tableGravatar Mike Klein2017-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | Looks like the color-space images have this well tested (even without lab_to_xyz) and the diffs look like rounding/FMA. The old plan to keep loads and stores outside callback was: 1) awkward, with too many pointers and pointers to pointers to track 2) misguided... load and store stages march ahead by x, working at ptr+0, ptr+8, ptr+16, etc. while callback always wants to be working at the same spot in the buffer. I spent a frustrating day in lldb to understood 2). :/ So now the stage always store4's its pixels to a buffer in the context before the callback, and when the callback returns it load4's them back from a pointer in the context, defaulting to that same buffer. Instead of passing a void* into the callback, we pass the context itself. This lets us subclass the context and add our own data... C-compatible object-oriented programming.
