With my previous changes Dolphin would fail to create the user directory if it didn't exist, and would dump all the configuration options in to the cwdir.
This was a bit more complicated to fix in a clean fashion, so I took to moving around code concerning user directories.
Instead of having GetUserPath serve a dual purpose of both getting and setting our user directories, break out to a new SetUserPath function.
GetUserPath will know only get the configured user path.
SetUserPath will set our user paths and setup the internal user path state.
This ending up being a lot cleaner overall, which is nice. Also less mind bending when attempting to read the code.
So now we won't dump all of our configuration in to the cwdir if ~/.dolphin-emu isn't found.
Fixes issue 8371.
Clamping a rectangle correctly requires fully clamping all four
coordinates in the general case.
This should fix issue 6923, sort of; at least, it fixes the part where a
rectangle ends up with a nonsensical height after being clamped.
A bit more efficient if we are only pushing two VFP registers.
We can probably be a bit more efficient in the future by mixing paired loadstores in to the other paths as well.
Previously on FPR pushing and popping we would do a single STR/LDR per quad FPR we wanted to push/pop.
In most of our cases when we are pushing and popping VFP registers they will be consecutive registers that will save more efficiently using the NEON
loadstores that can do up to four quad registers.
So this can potentially cutting instructions down to ~1/4th the amount of instructions if the registers are all consecutive.
On the Cortex-A57 this is basically just an icache improvement, but on the Nvidia Denver this may be optimized to be more efficient. Either way it's a
win.
The Load directory wasn't being properly reassigned when the user path changed, which causes a bunch of issues with things loading from the wrong
place when using the -U option in Dolphin.
The UI should decide on where it wants the user directory, not our core system.
This is in anticipation of some upcoming work on Android which will need proper user directory setting.
Since libcommon.a is also the last library to be linked, this has the
totally hacky but useful side-effect that it doesn't require people to
modify CMake files for temporarily adding VTune code to other Dolphin
libraries.
The PowerPC CPU has bits in MSR (DR and IR) which control whether
addresses are translated. We should respect these instead of mixing
physical addresses and translated addresses into the same address space.
This is mostly mass-renaming calls to memory accesses APIs from places
which expect address translation to use a different version from those
which do not expect address translation.
This does very little on its own, but it's the first step to a correct BAT
implementation.
The Windows implementations of CharArrayFromFormatV() and
StringFromFormat() use the "C"/".1252" locale instead of the user
locale (using _vsnprintf_l). On non-Windows, the user locale was used.
This leads to bugs on non-Windows: the Overclock parameter was
serialised with the user locale ("0,279322" in some locale) and was
interpreted back as "0" (because the C locale is used for parsing the
string).
Make non-Windows CharArrayFromFormatV() and StringFromFormat()
consistent with their Windows counterpart.
The locale code is not enables for Android:: uselocale is only
available since API 21 and API 21 only supports C and C.UTF-8.
If we are compiling in the CRC32 hash, clang has an issue with casting a s32 to a u64.
Change our lens argument to a unsigned integer to fix the issue.
Intellisense doesn't like defines in PCH files, and it doesn't like the deleted
constructor for BitField. (I think it's being overly strict about the
"must have no non-default constructors" rule for classes in unions.)
Someone thought it would be a good idea to have the location as the first argument on the instruction.
Changed it to how it is supposed to be disassembled.
Optimistically assume used GQRs are 0 in blocks that only use one GQR, and
bail at the start of the block and recompile if that assumption fails.
Many games use almost entirely unquantized stores (e.g. Rebel Strike, Sonic
Colors), so this will likely be a big performance improvement across the board
for games with heavy use of paired singles.
Won't work with all games, but provides a nice way to spend extra CPU to make
a variable framerate game faster (e.g. Spyro or The Last Story), or to make
a game use less CPU at the cost of a lower framerate (e.g. Rogue Leader).
If we have a shift amount that is the full length of the source register then we have an invalid instruction.
This can happen when dealing with a couple of PowerPC instructions.
This same adjustment is already in the ARMv7 emitter.
