Before, Dolphin would randomly crash when updating the cheat search when automatic refresh was enabled. (Having a large number of addresses listed, e.g. by starting with an "any value" search, may contribute). The crash was due to QTableWidget::item returning nullptr in RefreshGUICurrentValues, presumably due to the table being resized on the UI thread while the emulated CPU thread was updating the values. I've fixed this by pausing the CPU thread for the entirety of OnNextScanClicked; this eliminated crashes in my testing.
With 12 uses of `JoinStrings` in the codebase vs 36 uses of `fmt::join`, fmtlib's range adapter for string concatenation with delimiters is clearly the preferred option.
Migrating `Common::CaseInsensitiveLess` to StringUtil.h will hopefully discourage rolling one's own solution in the future for case-insensitive associative containers when this (quite robust!) solution already exists.
`Common::CaseInsensitiveStringCompare::IsEqual` was removed in favor of using the `Common::CaseInsensitiveEquals` function.
The `a.size() != b.size()` condition in `Common::CaseInsensitiveEquals` can be removed, since `std::ranges::equal` already checks this condition (confirmed in libc++).
There were three distinct mechanisms for signaling breakpoint changes in DolphinQt, and the wiring had room for improvement. The behavior of these signals has been consolidated into the new `Host::PPCBreakpointsChanged` signal, which can be emitted from anywhere in DolphinQt to properly update breakpoints everywhere in DolphinQt.
This improves a few things:
- For the `CodeViewWidget` and `MemoryViewWidget`, signals no longer need to propagate through the `CodeWidget` and `MemoryWidget` (respectively) to reach their destination (incoming or outgoing).
- For the `BreakpointWidget`, by self-triggering from its own signal, it no longer must manually call `Update()` after all of the emission sites.
- For the `BranchWatchDialog`, it now has one less thing it must go through the `CodeWidget` for, which is a plus.
The wrong filename was used so the settings weren't being applied.
The graphical issues reported were from enhancements that create graphical issues.
EFBToTextureEnable solves some graphical issues but those issues appear for only a few frames, the bulk of the game does not benefit while the setting while it is very sore on performance.
includes the following:
- org.DolphinEmu.dolphin-emu.metainfo.xml.in this file contains general
information and metadata that is used by most linux based app stores
(kde discover, gnome software, flathub.org, etc) to showcase dolphin.
- fill_release_node.sh a script to automatically fill in the release
information in the metainfo file when building the flatpak.
- SDL2.json manifest to build the vendored version of SDL from the
Exports directory, it's only temporarily needed until the kde runtime
is updated with the current SDL2 version and should be deleted after.
- org.DolphinEmu.dolphin-emu.yml the manifest itself.
Arbitrary Mipmap Detection doesn't work when GPU Texture Decoding is
enabled, so disable GPU Texture Decoding for games where the .ini
enables Arbitrary Mipmap Detection.

If texture dumping is enabled, notify the user on emulation startup
using an On Screen Display message.
Also notify the user when texture dumping is toggled.

The low-pass and biquad filters run in set40 mode where accessing ac#.m
returns the value of ac#.hm clamped to 16 bits.
This fixes the crackling in "Need for Speed: Nitro" (issue 13610).
Also make the lower bound match hardware (-0x8000 instead of -0x7FFF).
During 25-bit rounding, subnormals are "normalized"
This would normally mean that the exponent needs to be able to be <-1023
Instead, you can modify at what bit you round and get the same results!
This is done by finding the highest bit and shifting right the round bit

Changes integer rounding to more closely meet the documentation
The documentation explains to round before doing any bounds checks
All this really does is make sure some exception bits won't be set wrong
This depends on the rounding mode, fixing cases such as:
- Round to even, (0x7fffffff, 0x7fffffff.8)
- Round to down, (0x7fffffff, 0x80000000)
This change also uses some standard functions for rounding
Previously using them was casting to an s32 directly, now keeps the f64
RoundToIntegerMode introduced due to roundeven not being part of C++17
Finally, it can change a >0x7fffffff to >=0x80000000, done because:
- It looks nicer now with integers (I liked 0s)
- It gives ever so slightly better codegen on Aarch64

I wasn't aware that even with a size of zero, it's still not safe to pass a nullptr to `std::memcpy`. When `CachedInterpreterEmitter::PoisonCallback` is written, UB is happening.
Invert conditions, invert decrement checks, and make conditional branches unconditional. USnapshotMetadata in prior versions of Dolphin is forward-compatible with these changes (tested on x86_64).
