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).
This makes it possible to gracefully force stop emulation rather than
having to kill Dolphin completely when NetPlay deadlocks in the input
loop. Without a graceful stop, Wii saves do not get flushed to the main
NAND, and are left in limbo in the temporary NAND.
Doing pretty much anything in the controller config breaks NetPlay
(desync and/or deadlock), as saving the settings reconfigures
controller interfaces, which NetPlay doesn't expect.
This sends arbitrary packets in chunks to be reassembled at the other
end, allowing large data transfers to be speed-limited and interleaved
with other packets being sent. It also enables tracking the progress of
large data transfers.
Its usage was inconsistent, confusing, and buggy, so I opted to just
remove it entirely. It has been replaced with PadIndex for the
appropriate instances (mainly networking), and inappropriate usages
(where it was really just a player ID) have been replaced with the
PlayerId type. The definition of "no mapping" has been changed from -1
to 0 to match the defintion of "no player", as -1 (255 unsigned) is
actually a valid player ID.
The bugs never manifested because it only occurs with a full lobby of
255 players, at which point the last player's ID collides with the "no
mapping" definition and some undefined behavior occurs. Nevertheless, I
thought it best to fix it anyways as the usage of PadMapping was
confusing.
The interface address isn't particularly useful in most circumstances
(playing over internet), and we have a way to get the external IP now,
so displaying it in the dialog is useful.
Adds a tickbox to the server's window to syncronize codes. Codes
are temporarily sent to each client and are used for the duration of the
session.
Saves the "sync codes" tickbox as per PR Netplay: Properly save hosting
settings #7483
Previously, the Qt frontend would initialize the controller
interface on starting, resulting in the cursor position being
relative to the main window, instead of the render window.
