Lioncash 1ec3768b84 Gekko: Convert UReg_SDR1 over to using Common::BitField
Also fixes a typo in the struct name, since it was referring to SPR1
instead of SDR1. Given this isn't used anywhere yet, it's a painless
change.

Optimize division by a constant into multiplication. This method is

We also add optimized paths for divisors 0, 1, and -1, because they
don't work using this method. They don't occur very often, but are
necessary for correctness.

Lioncash e65363f05f NetKDRequest: Make use of constexpr arrays containing pairs instead of maps
Currently we were using heap allocating maps that last for the entire
duration of the emulator running.

Given the size N of both of these maps are very small (< 20 elements),
we can just make use of an array of pairs and perform linear scans. This
is also fine, given this code isn't particularly "hot" either, so this
won't be run often.

JosJuice f70ddebb40 JitArm64: Disable indexed paired loadstore instructions
Since the merge of b24b79e, we've gotten reports that the
following games are broken on JitArm64:

* Sonic Heroes
* The SpongeBob SquarePants Movie
* Astérix & Obélix XXL
* The Incredibles: Rise of the Underminer

Disabling the register cache avoids the issue, so the cause
of the bug might not actually have anything to do with the
newly implemented instructions. Nevertheless, I don't want
to ship a beta with this problem present, so I would like to
disable these instructions for the time being.

JosJuice 0cf8405126 JitArm64: Make HandleFastmemFault less unsafe
HandleFastmemFault works correctly when faults only happen in
expected locations, but it does some things that are rather
dangerous for faults in unexpected locations, like decrementing
an iterator without checking whether it's equal to begin.

This change cleans up the logic by making m_fault_to_handler's
key be the end of the fastmem region instead of the start.

JosJuice 90fcaf7e96 Jit: Use one less register in dcbx
We were using a "value" register to avoid clobbering physical_addr,
but this isn't actually needed anymore. The only bits we need from
physical_addr after we start clobbering it are bits 5-9, and
those bits are identical in effective_addr and physical_addr,
so we can read them from effective_addr instead.

`IsLess` would incorrectly return true if both `SR_OVERFLOW` and `SR_SIGN` are set, as `(sr & SR_OVERFLOW) != (sr & SR_SIGN)` becomes `SR_OVERFLOW != SR_SIGN` which is true as the two masks are different.  This broke in e651592ef5.

This issue only affected the DSP LLE Interpreter, and not the DSP LLE JIT.

I've also included a simple test case for this.  `ax0.l` (on the top left) is set to 0 if the instruction following `IFL` does not execute and to 1 if it is executed.

JosJuice 125af42e4b Jit: Re-add dcbx masking
When making 92d1d60, I checked whether the ~0x1f masking in dcbx
actually was necessary. I came to the conclusion that it wasn't,
so I removed it. However, I hadn't checked the second half of
InvalidateICache closely enough - the masking is actually needed.

This commit re-adds the masking, but this time in C++ code instead
of in jitted code in order to save icache. Though I suppose the
difference doesn't matter all that much, since this is in farcode
and all...

Hopefully fixes https://bugs.dolphin-emu.org/issues/12612.

Write_U16_Swap leaves the upper 32 bits alone. Reimplementing this
correctly in the JIT would require more than one instruction,
so let's just call Write_U16_Swap instead, like Jit64 does.

which memory is mapped in this way.

Techjar 797d0b7b1b VI: Implement post-scanout XFB output
This adds about a frame of latency, and since most games don't change
VI registers during scanout, we can get away with outputting the XFB at
the start of scanout. WWE Crush Hour is the (only currently known)
exception, which has flickering problems when doing it this way.

This adds a path to perform the output at the end of scanout, and gates
it behind an option which defaults to using the latency-reducing
pre-scanout path.

JosJuice 92d1d60ff1 Jit: Perform BAT lookup in dcbf/dcbi/dcbst
When 66b992c fixed https://bugs.dolphin-emu.org/issues/12133,
it did so by removing the broken address calculation entirely and
always using the slow path. This caused a performance regression,
https://bugs.dolphin-emu.org/issues/12477.

This commit instead replaces the broken address calculation with
a BAT lookup. If the BAT lookup succeeds, we can use the old fast
path. Otherwise we use the slow path.

Intends to improve https://bugs.dolphin-emu.org/issues/12477.

JosJuice 302b47f5e6 JitArm64: Add temp reg parameter to Arm64RegCache::Flush
We currently have a bug when calling Arm64GPRCache::Flush with
FlushMode::MaintainState, zero free host registers, and at least
one guest register containing an immediate. We end up grabbing
a temporary register from the register cache in order to be
able to write the immediate to memory, but grabbing a temporary
register when there are zero free registers causes the least
recently used register to be flushed in a way which does not
maintain the state of the register cache.

To get around this, require callers to pass in a temporary
register in the GPR MaintainState case. In other cases,
passing in a temporary register is not required but can help
avoid spilling a register (if the caller already had a
temporary register at hand anyway, which in particular will
be the case in my upcoming memcheck pull request).

DSPHLE: Fix running and is_stream checks in AX HLE
A voice is considered running if and only if `running` equals 1,
not if `running` is not equal to 0.

This fixes https://bugs.dolphin-emu.org/issues/12508 because for some
reason *The Sims 2 - Castaway* sets `running` to 8 when a stream
finishes playing; previously our AX HLE would just loop the voice
and eventually crash after accessing invalid memory addresses.

Thanks to JMC47 and delroth's help, I've verified that this is the
correct check for the following ucodes:

GC:
* 0x3ad3b7ac
* 0x3daf59b9
* 0x4e8a8b21
* 0x07f88145
* 0xe2136399
* 0x3389a79e

Wii:
* 0x347112ba
* 0xfa450138
* 0xadbc06bd

And while I was fixing the running check, I noticed that the is_stream
field was also being handled incorrectly, so I've fixed that as well.

DSPHLE: Prevent AX GC and AX Wii symbol mixups
Putting AX functions from AXVoice.h in an anonymous namespace does
successfully prevent compilers from merging those functions and
allows us to avoid ODR violations.

However, tools such as gdb still mix up AX GC and AX Wii functions
and variables because those have the exact same symbol names.

This can be fixed by using inline namespaces which are transparent
at the source code level but forces AX GC and AX Wii symbols to be
different.

probably rather small, but still, it would be nice if we could
let the compiler do the work at compile-time. And that's exactly

code in farcode to keep it out of the icache when possible).

Pokechu22 e440b21640 DVDInterface: Fix decrypting reads clearing the drive state
This broke ejecting Wii discs while the game is running, as the drive state was set to Ready even when no disc was present, but other code still reported the missing disc, which confused games as you can't be both ready to read and have no disc.  That would cause games to show an unrecoverable error screen, instead of a "please insert the game disc" screen.

This only affected Wii games; the GameCube games used regular disc reads which worked fine.

JosJuice ac28b89fa5 NetPlay/Jit64: Avoid using software FMA
When I added the software FMA path in 2c38d64 and made us use
it when determinism is enabled, I was assuming that either the
performance impact of software FMA wouldn't be too large or CPUs
that were too old to have FMA instructions were too slow to run
Dolphin well anyway. This was wrong. To give an example, the
netplay performance went from 60 FPS to 30 FPS in one case.

This change makes netplay clients negotiate whether FMA should
be used. If all clients use an x64 CPU that supports FMA, or
AArch64, then FMA is enabled, and otherwise FMA is disabled.
In other words, we sacrifice accuracy if needed to avoid massive
slowdown, but not otherwise. When not using netplay, whether to
enable FMA is simply based on whether the host CPU supports it.

The only remaining case where the software FMA path gets used
under normal circumstances is when an input recording is created
on a CPU with FMA support and then played back on a CPU without.
This is not an especially common scenario (though it can happen),
and TASers are generally less picky about performance and more
picky about accuracy than other users anyway.

With this change, FMA desyncs are avoided between AArch64 and
modern x64 CPUs (unlike before 2c38d64), but we do get FMA
desyncs between AArch64 and old x64 CPUs (like before 2c38d64).
This desync can be avoided by adding a non-FMA path to JitArm64 as
an option, which I will wait with for another pull request so that
we can get the performance regression fixed as quickly as possible.

Techjar 8cfe49295f VideoCommon: Add fallback handling for bounding box when disabled or unsupported
The SDK seems to write "default" bounding box values before every draw
(1023 0 1023 0 are the only values encountered so far, which happen to
be the extents allowed by the BP registers) to reset the registers for
comparison in the pixel engine, and presumably to detect whether GX has
updated the registers with real values. Handling these writes and
returning them on read when bounding box emulation is disabled or
unsupported, even without computing real values from rendering, seems
to prevent games from corrupting memory or crashing.

This obviously does not fix any effects that rely on bounding box
emulation, but having the game not clobber its own code/data or just
outright crash is a definite improvement.

JosJuice 2c38d6419e Jit64: Emulate FMA accurately when determinism is enabled
When determinism is enabled, we either want all CPUs to use FMA or
we want no CPUs to use FMA. Until now, Jit64 has been been doing
the latter. However, this is inaccurate behavior, all CPUs since
Haswell support FMA, and getting JitArm64 to match the exact
inaccurate rounding used by Jit64 would be a bit annoying. This
commit switches us over to using FMA on all CPUs when determinism
is enabled, with older CPUs calling the std::fma function.

This commit adds support for compiling Dolphin for ARM on MacOS so that it can
run natively on the M1 processors without running through Rosseta2 emulation
providing a 30-50% performance speedup and less hitches from Rosseta2.

It consists of several key changes:

- Adding support for W^X allocation(MAP_JIT) for the ARM JIT
- Adding the machine context and config info to identify the M1 processor
- Additions to the build system and docs to support building universal binaries
- Adding code signing entitlements to access the MAP_JIT functionality
- Updating the MoltenVK libvulkan.dylib to a newer version with M1 support

JosJuice 68a5fc55d2 Interpreter: Fix fctiwx rounding
The interpreter implementation of fctiwx was treating rounding
mode 0 as "round to nearest, ties towards zero", which is not
an actual IEEE-754 rounding mode. The IBM document mentioned
in a comment at the top of the function, on the other hand,
treats rounding mode 0 as "round to nearest, ties to even",
which makes more sense.

This fixes one of JMC's console-recorded F-Zero GX replays on
JitArm64. (JitArm64 uses an interpreter fallback for fctiwx.)

I have tried to not alter any behavior or semantics with this

in CommandProcessor retain the ability to accidentally undo
another thread's write to the upper half or lower half
respectively. If that should be fixed, it should be done in a
separate commit for clarity. One thing did change: The places
where we were using += on a volatile variable (not an atomic
operation) are now using fetch_add (actually an atomic operation).

Tested with single core and dual core on x86-64 and AArch64.

If the number of objects varied, this would result in either missing objects on some frames, or too many objects on some frames; the latter case could cause crashes.  Since it used the current frame to get the count, if the FIFO is started before the FIFO analyzer is opened, then the current frame is effectively random, making it hard to reproduce consistently.

This issue has existed since the FIFO analyzer was implemented for Qt.

Sintendo 2cafa0a960 Jit64: divwux - Prefer three-operand IMUL
By taking advantage of three-operand IMUL, we can eliminate a MOV
instruction. This is a small code size win. However, due to IMUL sign
extending the immediate value to 64 bits, we can only apply this when
the magic number's most significant bit is zero.

To ensure this can actually happen, we also minimize the magic number by
checking for trailing zeroes.

Example (Unsigned division by 18)
Before:
41 BE E4 38 8E E3    mov         r14d,0E38E38E4h
4D 0F AF F5          imul        r14,r13

JosJuice b3b5016f54 Jits: Fix interpreter fallback handling of discarded registers
When the interpreter writes to a discarded register, its type
must be changed so that it is no longer considered discarded.

Fixes a 62ce1c7 regression.

Sintendo 47e16133e5 Jit64: divwx - Eliminate XOR for constant dividend
We normally check for division by zero to know if we should set the
destination register to zero with a XOR. However, when the divisor and
destination registers are the same the explicit zeroing can be omitted.
In addition, some of the surrounding branching can be simplified as
well.

Sintendo abc4c8f601 Jit64: divwx - Eliminate MOV for division by power of 2
Division by a power of two can be slightly improved when the
destination and dividend registers are the same.

Jit: Optimize block link queries by using hash tables
Repeated erase() + iteration on a std::multimap is extremely slow.

Slow enough that it causes a 7 second long stutter during some
transitions in F-Zero X (a N64 VC game that triggers many, many icache
invalidations).

And slow enough that JitBaseBlockCache::DestroyBlock shows up on a
flame graph as taking >50% of total CPU time on the CPU-GPU thread:
https://i.imgur.com/vvqiFL6.png

This commit optimises those block link queries by replacing the
std::multimap (which is typically implemented with red-black trees)
with hash tables.

Master: https://i.imgur.com/vvqiFL6.png / 7s stutters
(starting from 5.0-2021 and with branch following disabled)

This commit: https://i.imgur.com/hAO74fy.png / ~0.7s stutters, which
is pretty close to 5.0 stable. (5.0-2021 introduced the performance
regression and it is especially noticeable when branch following
is disabled, which is the case for all N64 VC games since 5.0-8377.)

HLE: Do not clobber 0x1800-0x3000 when using MIOS to fix IPL crash
MIOS puts patch data in low MEM1 (0x1800-0x3000) for its own use.
Overwriting data in this range can cause the IPL to crash when
launching games that get patched by MIOS.
See https://bugs.dolphin-emu.org/issues/11952 for more info.

Not applying the Gecko HLE patches means that Gecko codes will not work
under MIOS, but this is better than the alternative of having specific
games crash.

This particular range is kind of bizarre, and would only interpret

the extension byte mode.

As far as I know, based off the information on Wiibrew, we should be
considering all three values within this range as valid.

WiiUtils: Add helper functions to get emulated/real Bluetooth device
This adds a function to get the emulated or real Bluetooth device for
an active emulation instance. This lets us deduplicate all the
`ios->GetDeviceByName("/dev/usb/oh1/57e/305")` calls that are currently
scattered in the codebase and ensures Bluetooth passthrough is being
handled correctly.

This also fixes the broken check in WiimoteCommon::UpdateSource.
There was a confusion between "emulated Bluetooth" (as opposed to
"real Bluetooth" aka Bluetooth passthrough) and "emulated Wiimote".

This avoids some warnings, which were originally fixed by ignoring loads with a value of zero (see 636bedb207 / #3242).

Note that FifoCI will report some changes, but only on the first frame; these seem to be timing related as they don't happen if a different write is used to replace skipped ones.

MMU: Remove a bunch of useless swaps
The swaps are confusing and don't accomplish much.

It was originally written like this:

u32 pte = bswap(*(u32*)&base_mem[pteg_addr]);

then bswap was changed to Common::swap32, and then the array access
was replaced with Memory::Read_U32, leading to the useless swaps.

MMU: Fix SDR updates being silently dropped in some cases
While 6xx_pem.pdf §7.6.1.1 mentions that the number of trailing
zeros in HTABORG must be equal to the number of trailing ones
in the mask (i.e. HTABORG must be properly aligned), this is actually
not a hard requirement. Real hardware will just OR the base address
anyway. Ignoring SDR changes would lead to incorrect emulation.

Logging a warning instead of dropping the SDR update silently is a
saner behaviour.

IOS/FS: Add a scoped FD class to make it harder to leak FDs
This changes FileSystemProxy::Open to return a file descriptor wrapper
that will ensure the FD is closed when it goes out of scope.

By using such a wrapper we make it more difficult to forget to close
file descriptors.

This fixes a leak in ReadBootContent. I should have added such a class
from the beginning... In practice, I don't think this would have caused
any obvious issue because ReadBootContent is only called after an IOS
relaunch -- which clears all FDs -- and most titles do not get close
to the FD limit.

JosJuice b3f71f7cdc JitArm64: Allow DoJit at address 0 (fix launching Wii titles)
JitArm64::DoJit contains a check where it prints a warning and tries
to pause emulation if instructed to compile code at address 0. I'm
assuming this was done in order to provide a nicer error behavior
in cases where PC was accidentally set to null. Unfortunately, it
has started causing us problems recently, as 688bd61 writes and runs
some code at address 0 to simulate the PPC being held in reset.
What makes this worse is that calling Core::SetState from the CPU
thread is actually not allowed and will cause a deadlock instead of
the intended behavior. I don't believe there is anything on a real
console that would stop you from executing code at address 0 (as
long as the MMU has been set up to allow it), and Jit64::DoJit
doesn't contain any check like this, so let's remove the check.

JosJuice 62ce1c7653 Jits: Discard registers which we know will be overwritten
This commit adds a new "discarded" state for registers.
Discarding a register is like flushing it, but without
actually writing its value back to memory. We can discard
a register only when it is guaranteed that no instruction
will read from the register before it is next written to.

Discarding reduces the register pressure a little, and can
also let us skip a few flushes on interpreter fallbacks.
