It stores both the konst selection value for alpha and color channels (for two tev stages per ksel), and half of a swap table row (there are 4 total swap tables, which can be used for swizzling the rasterized color and the texture color, and indices selecting which tables to use are stored per tev stage in the alpha combiner). Since these are indexed very differently, the old code was hard to follow.
Per https://en.cppreference.com/w/cpp/preprocessor/replace#.23_and_.23.23_operators the `##` behavior is a nonstandard extension; this extension seems to be supported by all compilers we care about, but IntelliSense in visual studio doesn't correctly handle it, resulting in false errors in the IDE (but not when compiling).
Per https://en.cppreference.com/w/cpp/preprocessor/replace#Function-like_macros C++20 introduced a workaround, where `__VA_OPT__(, )` generates a comma if and only if `__VA_ARGS__` is non-empty.
This PR replaces all occurrences, with the exception of Externals, DSPSpy (which is not likely to be edited in MSVC and does not target C++20 currently), and JitArm64_Integer.cpp (which uses `Function(__VA_ARGS__)`, and thus does not ever need a comma).
Prior to 7854bd7109, this was used by the debugger for the OpenGL and D3D9 plugins to control logging (via PRIM_LOG and INFO_LOG/DEBUG_LOG in VideoCommon code; PRIM_LOG was changed in 77215fd27c), and also framedumping (removed in 64927a2f81 and 2d8515c0cf), shader dumping (removed in 2d8515c0cf and this commit), and texture dumping (removed in 54aeec7a8f). Apart from shader dumping, all of these features have modern alternatives, and shader source code can be seen in RenderDoc if "Enable API Validation Layers" is checked (which also enables source attachment), so there's no point in keeping this around.
This normalization was added in 02ac5e95c8, and changed to use floats in 4bf031c064. The conversion to floats means that sometimes there is insufficient precision for the normalization process, which results in values of NaN or infinity. Performing the whole process with doubles prevents that, but games also sometimes set the values to NaN or infinity directly (possibly accidentally due to the values not being initialized due to them not being used in the current configuration?).
The version of Mesa currently in use on FifoCI (20.3.5) has issues with NaN. Although this bug has been fixed (b3f3287eac in 21.2.0), FifoCI is stuck with the older version.
This change may or may not be incorrect, but it should result in the same behavior as already present in Dolphin, while working around the Mesa bug.
https://bugs.dolphin-emu.org/issues/12977 indicates that this happens on startup of Spider-Man 2, even in single-core. I don't have the game, so I can't directly determine why this is happening, but presumably real hardware does not hang in this case, so we can make it less obtrusive.
Looks like a copy-paste gone wrong. The compute shaders for the other
formats use a group size of 8 * 8, whereas the CMPR compute shader
is supposed to use a flattened 64 * 1 as I understand it.
This struct is the only one in BPMemory that uses u64 as its base. These fields are to allow viewing it as two u32s instead. It's not used by Dolphin right now, but it is used in the copy of BPMemory.h used by hwtests.
This also changes the behavior for the invalid gamma value, which was confirmed to behave the same as 2.2.
Note that currently, the gamma value is only used for XFB copies, even though hardware testing indicates it also works for EFB copies. This will be changed in a later commit.
The only remaining casts for these types that I know of are in TextureInfo (where format_name is set to the int version of the format, and since that affects filenames and probably would break resource packs, I'm not changing it) and in TextureDecoder_Common's TexDecoder_DrawOverlay, which will be handled separately.
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
