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.
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.
Selecting Dummy or Memory Card would pass wrong values to EXI::ChangeDevice and not work as expected
Changing path had no effect until device was changed as it didn't call EXI::ChangeDevice at all
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.
