* Refactor 4f gradients using trait templatesGravatar fmalita2016-03-21
| | | | | | | | | | | | | | | | Some 4f gradient housekeeping. 1) replace <DstPtrType, ColorProfile> specialization tuples with an enum covering all dest types (L32, S32, F16, F32) 2) group various template helpers into dest trait classes, specialized for each dest type (2a - conflate current dst_swizzle and scale_for_dest ops into one load op) R=reed@google.com,mtklein@google.com,herb@google.com GOLD_TRYBOT_URL= https://gold.skia.org/search2?unt=true&query=source_type%3Dgm&master=false&issue=1816883002 Review URL: https://codereview.chromium.org/1816883002
* SkNx refreshGravatar mtklein2016-03-21
| | | | | | | | | | | | | | | | | | | | - rearrange a bit - fewer macros - hooks for all operators - add left and right scalar operator overrides - add +=, &=, <<=, etc. - add SkNx_split() and SkNx_join() - simplify the many rsqrt() and invert() options to just what we actually use This refactoring pointed out that our float <-> int NEON conversions are not specialized, so I've implemented them. It seems nice that this is an error rather than silently falling back to serial code. It's unclear to me if split/join want to be external, static methods, or non-static methods (SkNx_join(), Sk4f::Join(), x.join()). Time will tell?

* sRGB support in Ganesh. Several pieces:Gravatar brianosman2016-03-21
| | | | | | | | | | | | | | | | | | | | | | sRGB support now also requires GL_EXT_texture_sRGB_decode, which allows us to disable sRGB -> Linear conversion when reading textures. This gives us an easy way to support "legacy" L32 mode. We disable decoding based on the pixel config of the render target. Textures can override that behavior (specifically for format-conversion draws where we want that behavior). Added sBGRA pixel config, which is not-really-a-format. It's just sRGBA internally, and the external format is BGR order, so TexImage calls will swizzle correctly. This lets us interact with sRGB raster surfaces on BGR platforms. Devices without sRGB support behave like they always have: conversion from color type and profile type ignores sRGB and always returns linear pixel configs.

* detach -> releaseGravatar mtklein2016-03-16
| | | | | | | | | | | | | The C++ standard library uses the name "release" for the operation we call "detach". Rewriting each "detach(" to "release(" brings us a step closer to using standard library types directly (e.g. std::unique_ptr instead of SkAutoTDelete). This was a fairly blind transformation. There may have been unintentional conversions in here, but it's probably for the best to have everything uniformly say "release".

* Generic 4f gradient T sampler fallbackGravatar fmalita2016-03-10
| | | | | | | | | | | | | | | | | | | Add a generic T sampler fallback impl which uses T series produced by subclasses mapTs() overrides. The fallback path uses the same interval structures as the current optimized linear4f impl, but always sorted in stop order (never inverted to match dx/increasing x order). Enable the new mechanism for 4f linear w/ perspective. Other boring changes: * relocate the interval builder (back) to the base class * add a private header for shared templates BUG=skia: GOLD_TRYBOT_URL= https://gold.skia.org/search2?unt=true&query=source_type%3Dgm&master=false&issue=1783823002 Review URL: https://codereview.chromium.org/1783823002

* remove 565 effects shadersGravatar caryclark2016-01-04
| | | | | | | | | | | | | | | This removes the 565 optimization for radial, linear, sweep, and picture shaders. The optimization gets little real-world use and has a reasonable fallback. This also permits removing the square root table for the radial gradient case.

* Unify some SkNx codeGravatar mtklein2015-12-14
| | | | | | | | | | | | | | | - one base case and one N=1 case instead of two each (or three with doubles) - use SkNx_cast instead of FromBytes/toBytes - 4-at-a-time Sk4f::ToBytes becomes a special standalone Sk4f_ToBytes If I did everything right, this'll be perf- and pixel- neutral. https://gold.skia.org/search2?issue=1526523003&unt=true&query=source_type%3Dgm&master=false BUG=skia: CQ_EXTRA_TRYBOTS=client.skia:Test-Ubuntu-GCC-GCE-CPU-AVX2-x86_64-Release-SKNX_NO_SIMD-Trybot Review URL: https://codereview.chromium.org/1526523003
* ubsan shift fixesGravatar caryclark2015-12-09
| | | | | | | | | | | Use an inline function that does a normal shift. When built for the sanitizer, add casts so that the shift is unsigned. Also make a few fixes to do unsigned shifts or avoid the shift altogether; and add an argument spec to some macros.
