Change 3367838 on 2017/03/28 by Richard.Wallis
Updated items from original shelved version by Mark Satt:
- Added MetalBackend.cpp to change main function string to have an initial crc + code length zero's
**Description below taken from Mark Satt's original verison of this in CL3343280**
Updated for Dev-Rendering's PSOs & integrates Richard's work on RHI shader libraries.
Replace the FShaderCache's cook-time binary shader cache with Dmitriy Dyomin's standalone FShaderCodeLibrary that saves all shader byte-code arrays to files named by the FSHAHash. This de-duplicates shaders so we only ever store the byte code once. Includes optional support for generating a platform specific library file - which Metal implements to provide a single Metal library. The platform-native implementation can perform more de-duplication and in the case of Metal has lower file overheads and will compress more efficiently.
- All of the support code for the FShaderCache's cook caching is gone, which affects all platforms. The FShaderCodeLibrary is currently supported by Cook-By-The-Book but can be used with iterate or child cookers - only DLC cooking requires further work.
- With further modifications it should be possible to support Cook-on-the-Fly as well (output directories would be needed in FShaderCodeLibrary::InitForCooking) and the file-access pattern should be changed to use async. IO so that Material loading is not considered complete until all required byte-code arrays are loaded into the FShaderCodeLibrary.
- For Metal archiving shaders this way will compile with debug information and the FShaderCodeLibrary, with some help from extensions to IShaderFormat, will save the debug information out into separate files during cooking - these can then be used to debug the game without having to locally recompile, recook & repackage but the shipped byte-code is stripped. Global shader caches are also subject to de-duplication in the library in order to support Metal's shader stripping.
- File Move operations need to respect the 'Replace' flag - for FShaderCodeLibrary to work we need Move to be atomic.
- This bumps the object version and will cause all content to recook.
- Native library support is optional - only Metal currently implements one, but so could Vulkan and D3D12. For Metal the big advantages are further de-duplication where different materials generate the same MetalSL text but a different FSHAHash, that the single Metal library has lower overhead and that as a single file it all compresses far better (esp. with LZMA - 5x smaller).
Change 3367854 on 2017/03/28 by Mark.Satterthwaite
Don't track or record draw call resources for non-OpenGL shader platforms in the shader-cache as it is unnecessary and makes it slower on the CPU than it needs to be.

Change 3372436 on 2017/03/30 by Uriel.Doyon
Added flags in UPrimitiveComponent to keep track of its state in the streaming manager.
This allows to avoid unnecessary callback and processing in begin destroy reattach and being destroy logic.
Removed the limitation of only processing UMeshComponent when handling spawed primitive.
This releases the level manager from having to manage dynamic primitives.
This improves performance by not having to manage dynamic references in the level manager.
Primitives managed as dynamic now have a callback when ever their proxy is udpated, handling
many cases automatically where previously a manual callback to notify would have been required.
Fixed an issue where primitives with no reference to streaming textures would loose they dynamic state
because of lack of references in the streamer.
Change 3372740 on 2017/03/30 by Chris.Bunner
[Experimental] Partial compute post process pipeline (r.PostProcess.PreferCompute).

DR - Fix static analysis
Change 3374544 on 2017/03/31 by Richard.Wallis
FShaderCache Parallel-Context-Aware Merged with FShaderCache Single Library.
Future Work
- This was done before Engine PSO were in so this now needs a refector in the recording and playback on pipeline states instead an emulate PSO in OpenGL Driver.
- Remove FShaderCacheState and replace the logic with FGraphicsPipelineStateInitializer which should be able to record from the RHI current pipeline state
- This would reduce the Locking required as it's naturally per thread/context and only the final record would need a lock

Copying Metal improvements from task stream, with some modifications:
- Off-by-default implementations for MTLFence & MTLHeap, including some small changes to the RHI interface for parallel contexts.
- Support for Apple's Instruments "Points of Interest" tool.
- Consolidation of some Mac & iOS compiler, memory and thread handling code.

Fixes scene captures ordering's backward compatibility.
Before, 2d scene captures were rendered before cube scene captures. The CaptureSortPriority broke backward compatibility by settings this new member to 0 in the USceneCaptureComponent's constructor. Since it is a higher come first policy, this CL set the default of this value to 1 in USceneCaptureComponent2D's constructor.

Async shader compiling now recreates scene proxies which are affected by the material which was compiled. This fixes crashes which were occuring as proxies cache various material properties, but applying compiled materials would not update these cached properties (bRequiresAdjacencyInformation).
* A new ensure has been added in FMeshElementCollector::AddMesh and FBatchingSPDI::DrawMesh to catch attempts to render with a material not reported in GetUsedMaterials

Metal Desktop Tessellation support from Unicorn.
- Apple: Metal tessellation support added to MetalShaderFormat, MetalRHI and incl. changes to engine runtime/shaders for Desktop renderer and enabled in ElementalDemo by default (OS X 10.11 will run SM4).
- Epic: Support for different Metal shader standards on Mac, iOS & tvOS which required moving some RHI functions around as this is a project setting and not a compile-time constant.
- Epic: Fragment shader UAV support, which is also tied to newer Metal shader standard like Tessellation.
- Epic: Significant refactor of MetalRHI's internals to clearly separate state-caching from render-pass management and command-encoding.
- Epic: Internal MetalRHI validation code is now cleanly separated out into custom implementations of the Metal @protocol's and is on by default.
- Epic: Various fixes to Layered Rendering for Metal.
- Omits Mobile Tessellation support which needs further revision.

Fix various errors with Metal UAV & Render-Pass Restart support so that we can use the Pixel Shader culling for DistanceField effects.
- Unfortunately Metal requires that a texture be bound to start a render-pass, so reuse the dummy depth-stencil surface from the problematic editor preview tile rendering.

IWYU CIS compile fix for iOS.
Change 3224366 on 2016/12/06 by Mark.Satterthwaite
Simplify some of the changes from CL# 3224220 so that we don't perform unnecessary clears.
- If the RenderPass is broken to issue compute or blit operations then treat the cached RenderTargetsInfo as invalid, unless the RenderPass is restarted.
- This guarantees that we don't erroneously ignore calls to SetRenderTargets if the calling code issues a dispatch between two RenderPasses that use the same RenderTargetsInfo.
Change 3224416 on 2016/12/06 by Uriel.Doyon
New default implementation for UPrimitiveComponent::GetStreamingTextureInfo using a conservative heuristic where the textures are stretched across the bounds.
Optimized UPrimitiveComponent::GetStreamingTextureInfoWithNULLRemoval by not handling registered components with no proxy (essentially hidden game / collision primitives).
Added blueprint support for texture streaming built data through FStaticMeshComponentInstanceData.
Fix for material texture streaming data not being available on some cooked builds.
Enabled split requests on all texture load requests (first loading everything visible and then loaded everything not visible).
This is controlled by "r.Streaming.MinMipForSplitRequest" which defines the minimum mip for which to allow splitting.
Forced residency are now loaded in two steps (visible, then forced), improving reactiveness.
Updated "stat streaming" to include "UnkownRefMips" which represent texture with no known component referencing them,
and also "LastRenderTimeMips" which related to timed primitives.
Changed "Forced Mips" so that it only shows mips that are loaded become of forced residency.
"Texture Streaming Build" now updates the map check after execution.
Removed Orphaned texture logic as this has become irrelevant with the latest retention priority logic.
Updated "r.streaming.usenewmetrics" so that it shows behavior before and after 4.12 improvements.
Change 3224532 on 2016/12/07 by Uriel.Doyon
Integrated CL 3223965 :
Building texture streaming data for materials does not wait for pending shaders to finish compilation anymore.

Improved deferred shadowing with MSAA by upsampling light attenuation intelligently in the base pass
* If the current fragment's depth doesn't match what was used for deferred shadowing, the neighbor (cross pattern) with the nearest depth's shadowing is used
* Edge artifacts can still occur where the upsample fails or the shadow factor was computed per-sample due to depth / stencil testing
* Indirect Occlusion from capsule shadows also uses the nearest depth neighbor UV for no extra cost

Editor fixes for 4.15:
- PostProcessTonemap can't fail to bind a texture to the ColorLUT or the subsequent rendering will be garbage: the changes for optimising stereo rendering forgot to account for the Editor's use of Views without States for the asset preview thumbnails. Amended the CombineLUT post-processing to allocate a local output texture when there's no ViewState and read from this when this situation arises which makes everything function again.
- Don't start render-passes without a valid render-target-array in MetalRHI.

Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.
Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.
* Every header now includes everything it needs to compile.
* There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
* There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
* Every .cpp file includes its matching .h file first.
* This helps validate that each header is including everything it needs to compile.
* No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
* You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
* There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
* No engine code explicitly includes a precompiled header any more.
* We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
* PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.
Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.

- made public headers compilable individually
- easier access to settings section delegates
- removed module singleton accessor
- moved non-trivial definitions into cpp files
- code & documentation cleanup
#UpgradeNotes:
- instead of ISettingsModule::Get() use FModuleManager::GetModulePtr<ISettingsModule>("Settings")
- instead of using FSettingsSectionDelegates assign delegates directly through the new ISettingsSection methods
