Behaviorally, this belongs within the netplay client. The server will
always transmit a known RTC value, so it doesn't even need a global for
this. Given the client receives the packet containing said RTC value, we can
store it as a member variable and provide an accessor for reading that
value.
This removes another global variable within the netplay code.
Reduces the amount of dependencies dragged in by the main window's
header. This also removes MainWindow.h includes elsewhere where they
aren't necessary, reducing the amount of UI files that need to be
recompiled if the main window's header changes.
Lessens the amount of files that have to be recompiled if
ConfigManager.h is modified. This also removes an indirect inclusion
within DolphinQt/Main.cpp.
Ensures they match their naming within the definition of the function.
In EmulateSwing's case, one parameter was erroneously named tilt_group,
when it's actually supposed to be swing_group.
These aren't necessary in the prototype, however they do apply in the
definition of the function. This just cuts down on line noise within the
prototypes.
This is only ever read from externally, so we can expose a getter that ensures that
immutability, while making the actual instance internal. Given the
filling out of these settings depends on packets received by the client
instance, it makes more sense to make it a part of the client itself.
This trims off one lingering global.
Avoids dragging in a bunch of includes from the header files, and also
reduces the amount of files that need to be recompiled if one of those
included headers' source content is ever changed.
Previously we wouldn't indicate if saving or loading these files
happened to fail. In some cases we'd only print out to the logger, but
this is a pretty poor way to tell a user of the interface that something
went wrong in a direct way (the logging messages aren't able to be localized
either).
Previously there was only one function under the NetPlay namespace,
which is kind of silly considering we have all of these other types
and functions existing outside of the namespace.
This moves the rest of them into the namespace.
This gets some general names, like Player, for example, out of the global namespace.
The documentation for setting cache entries dicates that the type must
either be BOOL, FILEPATH, PATH, STRING, or INTERNAL (with those exact
casings). Also, given we properly case it in other places, this is just
consistent.
The general convention for CMake is to use lowercase for commands, and
given we also follow that convention through most CMake files, this just
makes it more consistent.
We can just use a vector of a vector, which also has the benefit of
keeping the size accounted for as well, allowing us to get rid of a
count parameter for CodesToHeader().
Instead of using an out-reference, we can modernize these to return the
std::string directly. While we're at it, also remove the unused name
parameter.
Given we now use a base class for the interface, we can make all member
functions, types and constants that aren't directly related to
instructions private.
HID2.LSQE is the Load/store quantize enable bit for non-indexed format
instructions (which are psq_l, psq_lu, psq_st, and psq_stu). If this bit
is not set and any of these instructions are attempted to be executed,
then a program exception is supposed to occur.
This function was duplicated across all the opcode tables: the main info
tables, the interpreter tables, and the x86-64 JIT tables. However, we
can just make the type of the std::array parameter a template type and
get rid of this duplication.
const on a parameter being passed by value in a prototype doesn't actually signify
anything, these are only applicable in the definition, where they make
the opcode parameter immutable.
inline has external linkage, which doesn't really make sense here, given
the function is only used within this translation unit. So we can
replace inline with static.
While we're at it, the code within the function can also be compressed
to a single return statement.
Previously these were required to be built into the executable so that
the JIT portion of the DSP code would build properly, as the
x86-64-specifics were tightly coupled to the DSP common code. As this is
no longer the case, this is no longer necessary.
This adds a base class that is used to replace the concrete instance of
the x64 JIT pointer within DSPCore. This fully removes the direct use
(read: non-ifdefed) usage of x86-64-specifics within the main DSP code.
Said base can also be used for creating JITs for other architectures,
such as AArch64, etc.
This is one of the last things that needed to be done in order to
finally separate the x86-64-specific code from the rest of the common
DSP code. This splits the tables up similar to how it's currently done
for the PowerPC CPU tables.
Now, the tables are split up and within their own relevant source files,
so the main table within the common DSP code acts as the "info" table
that provides specifics about a particular instruction, while the other
tables contain the actual instruction.
With this out of the way, all that's left is to make a general base for
the emitters and we can then replace the x64 JIT pointer in DSPCore with
it, getting all x64 out of the common code once and for all.
While shuffling all the code around, the removal of the DSPEmitter
includes in some places uncovered indirect inclusions, so this also
fixes those as well.
Despite both being documented as read-only registers, only one of them
is truly read-only. An mtspr to HID1 will steamroll bits 0-4 with
bits 0-4 of whatever value is currently in the source register, the rest
of the bits are not modified as bits 5-31 are considered reserved, so
these ignore writes to them.
PVR on the other hand, is truly a read-only register. Attempts to write
to it don't modify the value within it, so we model this behavior.
This makes it much more straightforward to access WiimoteDevice
instances and also keeps the implementation details of accessing those
instances in one spot.
Given as all external accesses to the WiimoteDevice instances go through
this function, we can make the other two private.
Using reinterpret_cast (or a C-styled equivalent) to reinterpret
integers as floating-point values and vice-versa invokes undefined
behavior. Instead, use BitCast, which does this in a well-defined
manner.
According to PEM 3.3.6.1, if a division by zero occurs and FPSCR.ZE is
set, then the result of the instruction operation is unchanged (see
table 3-13). Similarly, if an invalid operation occurs and FPSCR.VE is
set, then the destination should also remain unchanged (see table 3-12).
Hardware also matches this behavior.
We were handling this for other relevant instructions, but we weren't
doing so for the arithmetic instructions. This corrects that.
This also alters our NI_* functions to return an FPResult type, which
allows us to see which kind of exception in particular is set in
exceptional cases. This is necessary for cases like the fdiv
instructions, which requires handling both ZE and VE being potentially
set.
These can be moved into the RegisterColumn constructor, which avoids
potential allocations in the case a std::function would otherwise need
to allocate to hold all of it's captured data.
Also tidy up the inclusion order while we're at it.
Previously the class was intermixing m_ prefixed variables and
non-prefixed ones, which can be misleading. Instead, we make the
prefixing consistent across the board.
Makes the values strongly-typed and gets more identifiers out of the
global namespace.
We are forced to use anything that is not "None" to mean none, because
X11 is garbage in that it has:
\#define None 0L
Because clearly no one else will ever want to use that identifier for
anything in their own code (and is why you should prefix literally
any and all preprocessor macros you expose to library users in public
headers).
Makes the enum values strongly-typed and prevents the identifiers from
polluting the PowerPC namespace. This also cleans up the parameters of
some functions where we were accepting an ambiguous int type and
expecting the correct values to be passed in.
Now those parameters accept a PowerPC::CPUCore type only, making it
immediately obvious which values should be passed in. It also turns out
we were storing these core types into other structures as plain ints,
which have also been corrected.
As this type is used directly with the configuration code, we need to
provide our own overloaded insertion (<<) and extraction (>>) operators
in order to make it compatible with it. These are fairly trivial to
implement, so there's no issue here.
A minor adjustment to TryParse() was required, as our generic function
was doing the following:
N tmp = 0;
which is problematic, as custom types may not be able to have that
assignment performed (e.g. strongly-typed enums), so we change this to:
N tmp;
which is sufficient, as the value is attempted to be initialized
immediately under that statement.
This changes the identifier to represent the x86-64 DSP emitter. If any
other JITs for the DSP are added in the future, they all can't use the
same generic identifier.
In cases where we just want a random value for a primitive arithmetic
type, we can wrap this in a template to allow convenient direct
assignment instead of keeping declaration and initialization separate
(making it more difficult to use values uninitialized). This also allows
the use of Common::Random with functions such as std::generate, making
it more flexible in how random values can be generated.
This is only ever used internally. Also change the std::string name over
to a const char*, so that we don't need to potentially allocate anything
on the heap at immediate runtime.
Previously, a total of 114 std::string instances would need to construct
(allocating on the heap for larger strings that can't be stored with
small string optimizations). We can just use an array of const char*
strings instead, which allows us to avoid this.
Given JitBase shouldn't include platform specifics, we can generalize this
preprocessor define and allow any JIT to use it to indicate that generated code should be logged.
While we're at it, also move these defines beneath the includes with the
rest of the defines.
Rather than introduce this handling in every system instruction that modifies
the FPSCR directly, we can instead just handle it within the data structure
instead, which avoids duplicating mask handling across instructions.
This also allows handling proper masking from the debugger register
windows themselves without duplicating masking behavior there either.
ChunkFile doesn't use any of the file utilities, so we can drop these
headers to avoid pulling in unnecessary dependencies. This also
uncovered a few indirect inclusions.
This only queries internal state, it doesn't modify it. With minor
adjustments to BTEmu, this also allows us to make its usage instance a
constant reference.
The required version of MSVC already supports [[maybe_unused]], so we
can utilize this here. When GCC 7 and clang 3.9 become hard
requirements, we can eliminate this macro entirely and replace it with
[[maybe_unused]].
UNUSED is quite a generic macro name and has potential to clash with
other libraries, so rename it to DOLPHIN_UNUSED to prevent that, as well
as make its naming consistent with the force inline macro
This is much better as prefixed double underscores are reserved for the
implementation when it comes to identifiers. Another reason its better,
is that, on Windows, where __forceinline is a compiler built-in, with
the previous define, header inclusion software that detects unnecessary
includes will erroneously flag usages of Compiler.h as unnecessary
(despite being necessary on other platforms). So we define a macro
that's used by Windows and other platforms to ensure this doesn't
happen.
Instead of globbing things under an ambiguous Common.h header, move
compiler-specifics over to Compiler.h. This gives us a dedicated home
for anything related to compilers that we want to make functional across
all compilers that we support.
This moves us a little closer to eliminating Common.h entirely.
Rather than have a separate independent variable that we need to keep
track of in conjunction with the JIT code buffer size itself, amend the
analyst code to use the code buffer constant in JitBase.
Now if the size ever changes, then the analyst will automatically adjust
to handle it.
Given the code buffer is something truly common to all JIT
implementations, we can centralize it in the base class and avoid
duplicating it all over the place, while still allowing for differently
sized buffers.
