Previously, PowerPC.h had four macros in it like so:
\#define rPS0(i) (*(double*)(&PowerPC::ppcState.ps[i][0]))
\#define rPS1(i) (*(double*)(&PowerPC::ppcState.ps[i][1]))
\#define riPS0(i) (*(u64*)(&PowerPC::ppcState.ps[i][0]))
\#define riPS1(i) (*(u64*)(&PowerPC::ppcState.ps[i][1]))
Casting between object representations like this is undefined behavior.
Given this is used heavily with the interpreter (that is, the most
accurate, but slowest CPU backend), we don't exactly want to allow
undefined behavior to creep into it.
Instead, this adds a helper struct for operating with the paired singles,
and replaces the four macros with a single macro for accessing the
paired-singles/floating-point registers.
This way, it's left up to the caller to explicitly decide how it wants to interpret
the data (and makes it more obvious where different interpretations of
the same data are occurring at, as there'll be a call to one of the
[x]AsDouble() functions).
These bits enable or disable paired-single execution based on how
they're set. If PSE isn't set, then all paired-single instructions are
illegal. If PSE is set, but LSQE isn't set, then psq_l, psq_lu, psq_st
and psq_stu are illegal to execute.
Also thanks go out to my roommate @Veegie for letting me use his Wii as
a blasting ground for tests, since mine isn't on hand right now. It only
caught on fire twice and only burned down half of the house through the
process; what a team player.
Several functions (and one variable) were being given external linkage.
Instead, relocate them all to anonymous namespaces to make them
internally linked.
Puts the comment in the header where it's more likely to be seen
initially. We can also remove the TODO, given doing nothing or returning
an error is what is generally done for the JIT interface if the JIT
instance isn't valid.
With 7aa305ea35 merged, all that remains
within Profiler.cpp is an unused function that just forwards to the
equivalent function within JitInterface. Given that, we can just remove
the source file.
This global belongs in the JitOptions structure, as it's a conditional
setting (A.K.A. option) that changes the behavior of what the JIT does.
Plus it keeps the scope of the variable constrained to the general area
it's intended to be used and nothing further.
swap32() has a const u8* overload that swaps the data being pointed to as
if it were a 32-bit word. We can just use that instead. It gets rid of
undefined behavior, as we're not type punning a pointer and dereferencing it,
and gets rid of the need to cast entirely.
In both cases of the x64 and AArch64 JITs, these would have const casted
away from them, followed by them being placed within an emitter and
having breakpoint instructions written in them.
In this case, we shouldn't be using const period if we're writing to the
emitted data.
Similar in nature to e28d063539 in which
this same change was applied to the x64 emitter.
There's no real requirement to make this const, and this should also
be decided by the calling code, considering we had places that would
simply cast away the const and carry on
Type punning like this is undefined behavior. Instead, we use std::memcpy to
copy the necessary data over, which is well defined (as it treats both
the source and destination as unsigned char).
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.
Makes it less error-prone to get state data from analog sticks (no need
to pass any locals), and also allows direct assignment, letting the
retrieved data be const.
Makes it less error-prone to get state data from tilt controls (no need
to pass any pointers to locals), and also allows direct assignment,
letting the retrieved data be const.
Makes it less error-prone to get state data from sliders (no need
to pass any locals), and also allows direct assignment, letting the
retrieved data be const.
Makes it less error-prone to get state data from cursors (no need
to pass any pointers to locals), and also allows direct assignment,
letting the retrieved data be const.
Makes it less error-prone to get state data from analog sticks (no need

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.
