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.
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:

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

(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.)
VideoCommon: Change the type of BPMemory.scissorOffset to 10bit signed: S32X10Y10
VideoBackends: Fix Software Clipper.PerspectiveDivide function, use BPMemory.scissorOffset instead of hard code 342
Oversight from #9545, which moved the "new game has been loaded" logic
to a separate OnNewTitleLoad function that has to be called explicitly
*after* a title has loaded.
Coupled with the commit that makes Dolphin not clobber 0x1800-0x3000
when using MIOS, this fixes Wind Waker and other MIOS-patched games
when they are launched from the System Menu.
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.
texture serialization and deserialization used to involve many memory
allocations and deallocations, along with many copies to and from
those allocations. avoid those by reserving a memory region inside the
output and writing there directly, skipping the allocation and copy to
an intermediate buffer entirely.
We don't actually need to do this until we bump targetSdkVersion
to Android 12 (which we can't do yet since we're not compatible
with scoped storage), but I figured I'd get it out of the way early.
Not tested on Android 12, but tested to not break stuff on Android 10.
This adds a CMake option (DOLPHIN_DEFAULT_UPDATE_TRACK) to allow
configuring SCM_UPDATE_TRACK_STR. This is needed to enable auto-updates
in Windows CMake builds by default.
fmt/format.h is included in the PCH, so we need to make sure fmt is
actually in the include path.
Not sure how Visual Studio + CMake manages to build without this.
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".

Specifically, 'Scooby-Doo! Mystery Mayhem', 'Scooby-Doo! Unmasked', 'Ed, Edd n Eddy: The Mis-Edventures', and the Wii version of 'Happy Feet'.
The JIT cache causes problems with emulated icache invalidation in these games, resulting in areas failing to load.
This avoids some warnings, which were originally fixed by ignoring loads with a value of zero (see 636bedb207784db2d58b9986464f6a863677b59e / #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.
They appear to relate to perf queries, and combining them with truely unknown commands would probably hide useful information. Furthermore, 0x20 is issued by every title, so without this every title would be recorded as using an unknown command, which is very unhelpful.
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.
