This more accurately represents what's going on, and also ends at 0 instead of 1, making some indexing operations easier. This also changes it so that position_matrix_index_cache actually starts from index 0 instead of index 1.
(Specifically, the copy for VertexLoaderManager::position_cache. The position matrix index happens elsewhere, and the float path still has special logic to copy to scratch3.)
This increases accuracy, fixing the white rendering in Major Minor's Majestic March. However, the hardware backends can only have one viewport and scissor rectangle at a time, while sometimes multiple are needed to accurately emulate what is happening. If possible, this will need to be fixed later.
I think this is a relic of D3D9. D3D11 and D3D12 seem to work fine without it. Plus, ViewportCorrectionMatrix just didn't work correctly (at least with the viewports being generated by the new scissor code).
These aren't particularly useful, and make the code a bit more confusing. If for some reason someone wants to test what happens when these functions are disabled, it's easier to just edit the code that implements them. They aren't exposed in the UI, so one would need to restart Dolphin to do it anyways.
If libusb fails to initialize, an assertion fails, but if that happens before the main window is created, then Dolphin just dies. Now, the panic alert is properly shown and the user can ignore it.
These messages hid other, more important, ones often. I have left AttemptMaxTimesWithExponentialDelay and GetSysDirectory/SetSysDirectory as info, since those are called infrequently and can be useful to the end-user.
This message would be logged, usually multiple times, for EVERY. SINGLE. PIXEL. That's pretty much useless and just makes the log unreadable. Plus, the current support (which acts as RGB8) is close enough that for end-user purposes, it's fine. I don't think the hardware backends support RGB565_Z16 and its antialiasing functionality correctly either, but they don't have similar logspam.
I.e. flush pokes before running an EFB peek, if the cache tile isn't present. If the cache tile is present, then EFB pokes should have been written to the cache tile and thus don't need to be flushed.
Previously, when Pause at End of Movie was disabled, the game would continue running as it should, but the menu bar would think the game was paused, showing the play button instead of the pause button. To make things worse, clicking the play button would then restart the game, instead of pausing or doing nothing. F10 paused/unpaused as normal, though.
The old behavior was essentially to enable stepping/pause mode (via `CPU::Break()`) and then if Pause at End of Movie was disabled, to un-pause on the host thread (via `CPU::EnableStepping(false)`). For reasons which aren't entirely clear to me, the first one notified the menu bar (through the `Host::UpdateDisasmDialog` callback, not the `Settings::EmulationStateChanged` one), and the second did not. In any case, this approach does not particularly make sense; I don't see any reason to pause and unpause if Pause at End of Movie is disabled; instead, we should only pause when Pause at End of Movie is enabled.
This behavior was probably introduced in c1944f623b, though I haven't tested it.
directly_mapped_vars was added in #69 (4129b30494), but for some reason FIFO_BP_LO/HI were split out from it in in #885 (65af90669b). As far as I can tell, this code (and the code that existed at the time) is identical, so there's no reason to have it handled separately.
The DSP JIT only applies on x64, so if it doesn't work on esoteric compilers then that's not a problem. (And if it fails to compile, then it'll still produce an error on that platform, just no warnings on other platforms)
The size variable started to be unused when I created std::array variants of ReadArray, but we should follow it in case any files have fewer registers stored than they should (otherwise the remaining registers would end up with garbage data from later in the fifolog). Though, there probably aren't many fifologs where this is relevant.
Large amounts of logging can have an impact on performance, so moving the ones that have been determined to not matter to the warn level gives a way to hide those messages without hiding actual errors (and also gives a fast visual way of distinguishing between ignored and non-ignored ones due to the different colors).
It doesn't make sense for alpha to add the bias ONLY when dividing by 2, while color doesn't apply the bias for divide by 2 only; hardware testing indicates that alpha should have the bias.
This fixes the menus in Mario Kart Wii (https://bugs.dolphin-emu.org/issues/11909) but reintroduces the white rectangle in Fortune Street.
This reverts commit 5aaa5141ed (and several other matching changes elsewhere).
At least in GLSL, after calling EmitVertex() the value of all 'out' variables (including gl_Layer and ps) becomes undefined. On OpenGL it seems like they were unchanged, but on Vulkan they became 0, resulting in bad rendering.

DiscIO depends on some IOS functions and other functions, which are in Core and not Common. This results in link errors if using DiscIO on its own (which is why DolphinTool had a listed dependency on videocommon; videocommon has a dependency on core so adding that made things build).
Using unsigned char* or signed char* results in a deprecation warning, which is treated as an error. It needs to be casted to regular char* for it to work.
At least in MSVC (which is not restricted from targetting C++20), these can be resolved to either std::format_to or fmt::format_to (though I'm not sure why the std one is available). We want the latter.
