The inst.SIMM_16 change is for readability (though it also fixes a warning about potentially unintended uses of `||`).
The fallback change is because `b` is only meaningful for indexed instructions; this could theoretically lead to unintended fallbacks (but it seems unlikely).
Added AchievementManager class. Upon startup (currently only in DolphinQt), logs into RetroAchievements with the login credentials stored in achievements.ini.

Added AchievementSettings in Config with RA_INTEGRATION_ENABLED, RA_USERNAME, and RA_API_TOKEN. Includes code to load and store from Achievements.ini file in config folder.
Adds the rcheevos library from RetroAchievements to the Dolphin Externals as a submodule. Change was verified to import correctly and build both via Visual Studio and via cmake ninja.
We have these for a reason. I think this also fixes a theoretical
problem when `ABI_PARAM1 == loop_counter` where the first MOV destroys
the second's value; I'm not sure if this can actually happen in practice
though.
Will manually controlling both an accelerometer and a gyroscope at the
same time be reasonable to do? No idea. Was this easy to implement
thanks to the input override system? Yes.
Fixes https://bugs.dolphin-emu.org/issues/12443.
Up until now, there have been two settings on Android that stored the
selected Wii Remote extension: the normal one that's also used on PC,
and a SharedPreferences one that's used by the overlay controls to
determine what controls to show. It is possible for these two to end up
out of sync, and my input changes have made that more likely to happen.
To fix this, let's rework how the overlay controller setting works.
We don't want it to encode the currently selected Wii Remote extension.
However, we can't simply get rid of the setting, because for some Wii
games we need the ability to switch between a GameCube controller and a
Wii Remote. What this commit does is give the user the option to select
any of the 4 GameCube controllers and any of the 4 Wii Remotes. (Before,
controllers 2-4 weren't available in the overlay.) Could be useful for
things like the Psycho Mantis fight in Metal Gear Solid. I'm also
switching from SharedPreferences to Dolphin.ini while I'm at it.
This is a small regression from KillRenderer, which caused duplicated
frames to be counted on the FPS counter when the "Skip Presenting
Duplicated Frames" option was disabled.
This way, Android (which will show groups in the order they're defined)
will show groups in a more logical order similar to DolphinQt.
The main thing that was annoying me was how early Rumble was for
Wii Remotes. Some of the other changes I'm making in this commit,
like the order of Shake/Tilt/Swing, are more arbitrary and were
made for consistency with DolphinQt. But there are also places
where I didn't go all the way with matching DolphinQt. Most notably,
DolphinQt puts sticks before buttons, but I don't see any reason
to do that for Android.
Unlike PCs, Android doesn't really have any input method (not counting
touch) that can reasonably be expected to exist on most devices.
Because of this, I don't think shipping with a default mapping for the
buttons and sticks of GameCube controllers and Wii Remotes makes sense.
I would however like to ship default mappings for a few things:
1. Mapping the Wii Remote's accelerometer and gyroscope to the device's
accelerometer and gyroscope. This functionality is useful mainly
for people who use the touchscreen, but can also be useful when
using a clip-on controller. The disadvantage of having this mapped
by default is that games disable pointer input if the accelerometer
reports that the Wii Remote is pointed at the ceiling.
2. Mapping GC keyboards for use with a physical keyboard, like on PC.
After all, there's no other way of mapping them that makes sense.
3. Mapping rumble to the device's vibrator.
Aside from the GC keyboards, this approach is effectively the same as
what we were doing before the input overhaul.
This second stack leads to JNI problems on Android, because ART fetches
the address and size of the original stack using pthread functions
(see GetThreadStack in art/runtime/thread.cc), and (presumably) treats
stack addresses outside of the original stack as invalid. (What I don't
understand is why some JNI operations on the CPU thread work fine
despite this but others don't.)
Instead of creating a second stack, let's borrow the approach ART uses:
Use pthread functions to find out the stack's address and size, then
install guard pages at an appropriate location. This lets us get rid
of a workaround we had in the MsgAlert function.
Because we're no longer choosing the stack size ourselves, I've made some
tweaks to where the put the guard pages. Previously we had a stack of
2 MiB and a safe zone of 512 KiB. We now accept stacks as small as 512 KiB
(used on macOS) and use a safe zone of 256 KiB. I feel like this should
be fine, but haven't done much testing beyond "it seems to work".
By the way, on Windows it was already the case that we didn't create
a second stack... But there was a bug in the implementation!
The code for protecting the stack has to run on the CPU thread, since
it's the CPU thread's stack we want to protect, but it was actually
running on EmuThread. This commit fixes that, since now this bug
matters on other operating systems too.
This broke formatting the system memory; see https://bugs.dolphin-emu.org/issues/13176. After calling ticket.DeleteTicket(), ticket.m_bytes was 0-length, but calling ticket.IsV1Ticket() still attempted to read from m_bytes.
This was introduced in 2fd9852ca8, although it didn't actually cause a crash until 929fba08e7.
When faced with this error, users often don't try disabling dual core,
even though the error message suggests it. Perhaps the message is just
too long and lists too many things?
To try to improve the situation, I'm rewording the message and making it
say different things depending on what settings you are using.
The LEA that the signal handler is trying to undo the effects of is a
32-bit instruction, and the value in the register prior to the LEA is
also 32-bit, so the signal handler should use a 32-bit write.
(Actually, in the end this doesn't really matter, because the first
instruction that reads this value after backpatching is also a 32-bit
instruction...)
This fixes a regression from 592ba31. When `a` was a constant 0 and `b`
was a non-constant 0x80000000, the 32-bit negation operation would
overflow, causing an incorrect result. The sign extension needs to happen
before the negation to avoid overflow.
Note that I can't merge the SXTW and NEG into one instruction.
NEG is an alias for SUB with the first operand being set to ZR,
but "SUB (extended register)" treats register 31 as SP instead of ZR.
I've also changed the order for the case where `a` is a constant
0xFFFFFFFF. I don't think the order actually affects correctness here,
but let's use the same order for all the cases since it makes the code
easier to reason about.
The previous code only updated the PLRU on cache misses, which made it so that the least recently inserted cache block was evicted, instead of the least recently used/hit one.
This regressed in 9d39647f9e (part of #11183, but it was fine in e97d380437), although beforehand it was only implemented for the instruction cache, and the instruction cache hit extremely infrequently when the JIT or cached interpreter is in use, which generally keeps it from behaving correctly (the pure interpreter behaves correctly with it).
I'm not aware of any games that are affected by this, though I did not do extensive testing.
Previously we would only backpatch overflowed address calculations
if the overflow was 0x1000 or less. Now we can handle the full 2 GiB
of overflow in both directions.
I'm also making equivalent changes to JitArm64's code. This isn't because
it needs it – JitArm64 address calculations should never overflow – but
because I wanted to get rid of the 0x100001000 inherited from Jit64 that
makes even less sense for JitArm64 than for Jit64.
This fixes a problem I was having where using frame advance with the
debugger open would frequently cause panic alerts about invalid addresses
due to the CPU thread changing MSR.DR while the host thread was trying
to access memory.
To aid in tracking down all the places where we weren't properly locking
the CPU, I've created a new type (in Core.h) that you have to pass as a
reference or pointer to functions that require running as the CPU thread.
This code doesn't need to be portable (since the goal is to have a smaller offset for x64 codegen), so if it's not supported there are other problems. Similar code exists in e.g. DSP.cpp.
The logging was broken in 958cbf38a4 (DSPTool doesn't use dolphin's logging system, so it just produced nothing; the same thing affected comparing before 693a29f8ce).
AssemblerError::LabelAlreadyExists (previously ERR_LABEL_EXISTS) simply was never used.
This reverts commit e140516130. This assert triggers for AX and AXWii uCode games (including the Wii System Menu) for various addresses that seem to be 4-byte aligned. Worse still, if the DSP thread is in use (i.e. for DSP LLE recompiler, but not for DSP LLE interpreter), Dolphin completely hangs after the panic alert. Perhaps the data DMA has fewer restrictions compared to the instruction DMA?
The change to DSPTool (e391a28102) has not been reverted, as it still fixes broken behavior for DSPSpy at -O0 on real hardware.
Gives two members without explicit initialization default values to be
consistent with the rest of the class and also ensuring deterministic
values on construction.
Though less important compared to #11470, save states also show the full path in the OSD message and could potentially dox a streamer who is playing in Dolphin. This is a simple fix - it removes the path from the message and only displays the file name.

Re-jig code to exit early and read easier
I haven't tested this extensively on real hardware, but I do know that bad things happen if the address isn't properly aligned, and libogc says it should be 32-byte aligned.
Turns out all OSD messages, every single one, are written to the titlebar. We've just never seen them because the FPS is in the title bar and it replaces it in a fraction of a second. This was only visible when saving savestates because it halts emulation for a moment while writing.
This is dumb, let's not do that anymore.
A few weeks ago, a vtuber tweeted that they had to remove a vod of their stream because Dolphin Emulator showed some personal information during the steam, and left a warning to everyone else that Dolphin shows the account name of the computer. And yea, we do, we show the full directory of the memory card every time a memory card is written, and due to mandatory Microsoft account nonsense, that is very likely to contain someone’s real name.
Fortunately this is very easy for us to solve. This change simply removes the filename from wrote memory card contents string. That’s it. All functionality of the wrote memory card OSD message remains the same, it just doesn’t say where the memory card is anymore.
There are lots of other potential solutions to this but after talking on IRC it seems the simplest one is the best.

See the comment added by this commit. We were previously guarding against
overshooting in address calculations, but not against undershooting.
Perhaps someone assumed that the displacement of an x86 loadstore was
treated as unsigned?
Note: While the comment says we can undershoot by up to 2 GiB, in
practice Jit64 as it currently behaves won't actually undershoot by more
than 0x8000 if my analysis is correct. But address space is cheap, so
let's guard the full 2 GiB.
Plus two miscellaneous debugger features that I found along the way when
reading Jit64's code for comparison: bJITNoBlockLinking and tracing.
Fixes https://bugs.dolphin-emu.org/issues/13127.
Small optimization. By not calling WriteExit, the block linking system
never finds out about the exit we're doing, saving us from having to
disable block linking.
Previously, if a user on Windows launched Dolphin from the command line
and specified a path to an M3U file and included backslashes in this path,
Dolphin would fail to resolve relative paths in the M3U file.
The calculation of each address in lmw/stmw currently has a dependency
on the calculation of the previous address. By removing this dependency,
the host CPU should be able to pipeline the loads/stores better. The cost
we pay for this is up to one extra register and one extra MOV instruction
per guest instruction, but often nothing.
Making EmitBackpatchRoutine support using any register as the address
register would let us get rid of the MOV, but I consider that to be too
big of a task to do in one go at the same time as this.
Now that we've flipped the C++20 switch, let's start making use of
the nice new <bit> header.
I'm planning on handling this move away from BitUtils.h incrementally
in a series of PRs. There may be a few functions remaining in
BitUtils.h by the end that C++20 doesn't have any equivalents for.
This reverts commit 351d095fff.
In hindsight, my attempted optimization messes with the return
predictor, unlike real tail calls. So I think it does more bad than
good.
Use: callstack(0x80000000).
!callstack(value) works as a 'does not contain'.
Add strings to expr.h conditionals.
Use quotations: callstack("anim") to check symbols/name.
For quite some time now, we've had a setting on x86-64 that makes Dolphin
handle NaNs in a more accurate but slower way. There's only one game that
cares about this, Dragon Ball: Revenge of King Piccolo, and what that game
cares about more specifically is that the default NaN (or "generated NaN"
as I believe it's called in PowerPC documentation) is the same as on
PowerPC. On ARM, the default NaN is the same as on PowerPC, so for the
longest time we didn't need to do anything special to get Dragon Ball:
Revenge of King Piccolo working. However, in 93e636a I changed how we
handle FMA instructions in a way that resulted in the sign of NaNs
becoming inverted for nmadd/nmsub instructions, breaking the game.
To fix this, let's implement the AccurateNaNs setting, like on x86-64.
