TellowKrinkle 6ab24e6c17 VideoCommon: Better driver bug handling
Adds a pass to process driver deficiencies between UID caching and use, allowing a full view of the whole pipeline, since some bugs/workarounds involve interactions between blend modes and the pixel shader

Pokechu22 b5844ab195 PixelShaderGen: always run indirect stage logic
Hardware testing has confirmed that fb_addprev and wrapping both run even when the indirect stage is disabled.

Pokechu22 002ff4e4dd PixelShaderGen: Remove unused num_texgens argument
It became unused in f039149198.

Pokechu22 072304404c Correct indirect stage ref typos
YAGCD uses BI0/BC0/BI1/BC1/BI2/BC2/BI3/BC3, so I'm pretty sure the BI2/BC3/BI4/BC4 names are a typo that just was propagated.

Pokechu22 70f9fc4e75 Convert BPMemory to BitField and enum class
Additional changes:
- For TevStageCombiner's ColorCombiner and AlphaCombiner, op/comparison and scale/compare_mode have been split as there are different meanings and enums if bias is set to compare.  (Shift has also been renamed to scale)
- In TexMode0, min_filter has been split into min_mip and min_filter.
- In TexImage1, image_type is now cache_manually_managed.
- The unused bit in GenMode is now exposed.
- LPSize's lineaspect is now named adjust_for_aspect_ratio.

Stenzek 51724c1ccd LightingShaderGen: Always calculate lighting for both color channels
Cel-damage depends on lighting being calculated for the first channel
even though there is no color in the vertex format (defaults to the
material color). If lighting for the channel is not enabled, the vertex
will use the default color as before.

The default value of the color is determined by the number of elements in
the vertex format. This fixes the grey cubes in Super Mario Sunshine.

If the color channel count is zero, we set the color to black before the
end of the vertex shader. It's possible that this would be undefined
behavior on hardware if a vertex color index that was greater than the
channel count was used within TEV.

Lioncash 5de2244acf PixelShaderGen: Migrate over to fmt
Continues the migration of the shader generators over to fmt.

After this, all that remains in the Ubershader pixel generator.

Lioncash 149a97e396 VideoCommon: Remove unnecessary memset on ShaderUid instances.
Zero-initialization zeroes out all members and padding bits, so this is
safe to do. While we're at it, also add static assertions that enforce
the necessary requirements of a UID type explicitly within the ShaderUid
class.

This way, we can remove several memset calls around the shader
generation code that makes sure the underlying UID data is zeroed out.
Now our ShaderUid class enforces this for us, so we don't need to care about
it at the usage sites.

Stenzek 68cb24172b ShaderGen: Omit some unused varyings when possible
Removes the clipPos varying unless slow-depth is used, and the
clipDistance varyings if geometry shaders are not used.

Jonathan Hamilton 29a9ed043b Implement dual-source blending in shader
For some GLES drivers that don't support dual-source blending, but do
support GL_EXT_shader_framebuffer_fetch, this might be useful.

Stenzek 84f8ebd95f VideoBackends: Clear uid bits that are unused for the current backend
Currently, this is only the logic op bit, but this will be extended to
the framebuffer fetch/blend modes. In the future, when/if we move to
VideoCommon pipelines, this state will be part of the pipeline UID
anyway, and we can mask it out in the backend by using a two-level map,
so the shaders/programs are shared.

Stenzek 0622979d3b ShaderGen: Support writing integer colors when logic op is enabled

degasus 083be0832f LightingShader: Drop xfmem usage.
Our shaders must only depend on the UID, not on any global state.

degasus 829fc8f0ad PixelShaderGen: Drop dstAlphaMode constant in shader generation.
It is already stored within the UID.

Lioncash 14e0b48ae4 VideoCommon: Make API_TYPE an enum class
Allows for forward declarations in most places, which prevents dumping
unrelated VideoCommon.h contents directly into headers.

Scott Mansell ebe5fd0b36 Multithreadded Shadergen: Minor fixups. 2016-06-26 16:13:22 +12:00
Scott Mansell 24e5d21780 Multithreadded Shadergen: Second pass over Pixel Shadergen.
Note: It's not 100% perfect, as some of the GPU capablities leak into the
pixel shader UID.

Currently our UIDs don't get exported, so there is no issue. But someone
might want to fix this in the future.

Scott Mansell 0d996f512b Multithreadded Shadergen: First pass over pixel Shadergen
Bug Fix: It was theoretically possible for a shader with depth writes
         disabled to map to the same UID as a shader with late depth
	 writes.
	 No known test cases trigger this.

Scott Mansell e99364c7c9 UID Change: Fix bug with indirect stage UIDs
Bug Fix: The normal stage UIDs were randomly overwriting indirect
         stage texture map UID fields. It was possible for multiple
	 shaders with diffrent indirect texture targets to map to
	 the same UID.
         Once again, it dpesn't look like this bug was ever triggered.

Scott Mansell 03f2c9648d Shader UID change: Only store the two bits of components we need.
This frees up 21 bits and allows us to shorten the UID struct by an entire
32 bits.

It's not strictly needed (as it's encoded into the length) but I added a
bit for per-pixel lighiting to make my life easier in the following
commits.

Jules Blok 6d1628eda4 Revert "Merge pull request #3578 from Armada651/forced-slow-depth"
This reverts commit e2a1a085b6, reversing
changes made to 2aea549eef.
2016-02-29 00:55:51 +01:00
Jules Blok 9805f70913 VideoConfig: Replace FastDepthCalc by ForcedSlowDepth.
Fast depth is now more accurate than slow depth and should always be used.
The option will be kept in a different form as it is still used as a hack to fix some games.
Also, the slow depth code path will still be relied upon by cards that don't support GL_ARB_clip_control.

These aren't used outside of it. This also reduces the amount of things in

NanoByte011 613781c765 Cleanup and refactor of zfreeze port
Based on the feedback from pull request #1767 I have put in most of
degasus's suggestions in here now.

I think we have a real winner here as moving the code to
VertexManagerBase for a function has allowed OGL to utilize zfreeze now
:)

Correct use of the vertex pointer has also corrected most of the issue
found in pull request #1767 that JMC47 stated.  Which also for me now
has Mario Tennis working with no polygon spikes on the characters
anymore!  Shadows are still an issue and probably in the other games
with shadow problems.  Rebel Strike also seems better but random skybox
glitches can show up.

NanoByte011 937844b9e3 Initial port of zfreeze branch (3.5-1729)
Initial port of original zfreeze branch (3.5-1729) by neobrain into
most recent build of Dolphin.

Makes Rogue Squadron 2 very playable at full speed thanks to recent core
speedups made to Dolphin. Works on DirectX Video plugin only for now.

Enjoy!  and Merry Xmas!!
