After 3a83ebc, the Show System Clock feature started using the
unfortunate combination of MM/DD/YY dates (rare outside of the US)
and 24-hour time (rare in the US) regardless of the user's locale
settings. This commit makes it use the configured locale again.
I've noticed one minor difference in behavior between now and
before 3a83ebc: The new way of setting the C/C++ locale seems to
treat "en" as "en-US", but the wx way of setting the C locale
treated it as "en-GB" (at least on Windows).
Migrates the state to be instance-based as opposed to being a flat
namespace. This keeps behavior localized to its own instantiable unit
(and forces uses of the class to also be localized, lest they cart around
an instance all over the place).
This was necessary to work around a FS timing issue which caused small
writes to take much longer than they should.
Now that we emulate timings for the FS module including its file cache,
we don't need to maintain this workaround anymore.
Everything that links in core doesn't need to see anything related to bochs, because it's only used internally.
Anything else that relies on bochs should be linking it in explicitly.
The general convention is to return a reference to the object that was
acted on, otherwise you can get into situations with errors because the
type wasn't being propagated properly
Using this in its current form would invoke undefined behavior, as it's
using a union to type pun between data types. It's also, well, unused,
so we don't need to keep it around.
We already read the necessary information with the
HostRead_Instruction() call. Internally, it calls HostRead_U32() as
well, so there's no difference in behavior.
If the locked cache isn't enabled, dcbz_l is illegal to execute
(locked cache is off, locked cache instructions don't work, makes sense)
This makes exception handling more accurate. It was previously possible to hit the DSI exception
handler when HID2[LCE] is set to zero, which isn't correct.
With this change we no longer hit the DSI handler, however we still have a lingering issue elsewhere
likely to do with exception precedence, we seem to hit the Floating Point exception handler instead
in some cases. This isn't due to the instruction itself directly however, so this is just another bug
to fix elsewhere.
CMake already has this functionality built-in. This lessens depending on the host system environment
and is more cross-platform friendly (which is always nice from a build-system point of view).
In the case we had X11 libs available, we'd allocate an XRRConfiguration instance and pass it
to the GraphicsWindow instance, but it would never actually be freed.
add_definitions and include_directories don't operate on a by-target basis, they act on a
by-directory basis (i.e. if we defined two targets, A and B, in this CMakeLists file, add_definitions
would add the definitions to the COMPILE_DEFINITIONS directory property which both A and B would
implicitly use).
The same idea applies to include_directories, only it appends to the INCLUDE_DIRECTORIES directory
property.
Instead, specify these on the target to keep scope as narrow as possible.
This is one of the conditions for an alignment exception documented in
the 750CL architecture reference manual in section 4.5.6, which also
applies to the Gekko microprocessor.
This is an exception condition documented within section 4.5.6 in the
architecture reference manual for the PPC 750CL, which also applies to
the Gekko microprocessor.
Also moves dcbz_l's implementation out of Interpreter_Paired and beside
dcbz where it belongs.
The effective address given to these instructions must be word (4 byte) aligned,
and if the address is not aligned like that, then an alignment exception
gets triggered.
We currently don't update the DSISR in this case properly, since we
didn't really handle alignment exceptions outside of ecowx and eciwx,
and even then the handling of it isn't really that great, considering
the DAR isn't updated with the address that caused the exception to
occur.
The DSISR will eventually be amended to be properly updated.
Prior to this change, it's possible for m_wake_me_up_again to be used
while it's in an uninitialized state from the exposed API.
e.g.
- Using SetEnable after construction would perform an uninitialized read.
- Using PushEvent would perform an uninitialized read by way of operator |=.
internally, an uninitialized read can happen if PullEventsInternal() is
executed before other functions.
Just to avoid the whole possibility of performing uninitialized reads,
we just give the class member a default value of false.
If the copy assignment operator is deleted, then the copy constructor
should be deleted as well, otherwise it's a hole in the API where copies
can be made (and if this were an intended case, it should be
documented).
So we delete the copy constructor and explicitly default the move
assignment and move constructor to signify this is intended to be a
move-only type.
Adjusts Common to use the ICONV_LIBRARIES variable directly and doesn't
append it to the LIBS variable.
After this, there's only one remaining usage where libraries are added
to the LIBS variable, after which it can be removed once the rest of
the targets are migrated off add_dolphin_library
This way, if we load a UID cache where the data was incomplete (e.g.
Dolphin crashed), we don't lose the existing UIDs which were previously
at the beginning.
These are bit manipulation functions, so they belong within BitUtils.
This also gets rid of duplicated code and avoids relying on compiler
reserved names existing or not existing to determine whether or not we
define a set of functions.
Optimizers are smart enough in GCC and clang to transform the code to a
ROR or ROL instruction in the respective functions.
The only place this library is needed (core) is already linked in the core target.
Also make the linkage private to create linkage failures if the dependency isn't
explicitly linked in elsewhere where it should be.
Reduces the dependency on the LIBS variable.
Return a FileHandle which will automatically close the FD when
the handle goes out of scope. For the rare cases where this behaviour
is undesirable, the FD can be released from the handle.
This is the large change in the branch.
This lets us use either the host filesystem or (in the future) a NAND
image exactly the same way, and make sure the IPC emulation code
behaves identically. Less duplicated code.
Note that "FileIO" and "FS" were merged, because it actually doesn't
make a lot of sense to split them: IOS handles requests for both
/dev/fs and files in the same resource manager, and as it turns out,
/dev/fs commands can *also* be sent to non /dev/fs file descriptors!
If we kept /dev/fs and files split, there would be no way to
emulate that correctly. I'm not aware of anything that does that (yet?)
but I think it's important to be correct.
Now that we have a proper filesystem interface, it makes more sense
to return it instead of the emulated IOS device (which isn't
really usable for any purpose other than emulated IPC).
Extract the existing FS code into a HostBackend implementing
the filesystem interface.
Compared to the original code, this uses less static state.
The open host files map is now a member variable
as it should have been. Filesystem handles are now also easier
to savestate. Some variable names and log messages were cleaned up.
Nothing else has been changed.
Add a new FileSystem class that can be used to perform operations
on the emulated Wii filesystem.
This will allow separating the IPC code (reading from and writing to
memory to handle IOS FS commands) and the actual filesystem code
in a much better way.
This also paves the way for implementing another filesystem backend
in the future -- NAND images for more complete emulation, including
filesystem metadata like permissions or file orders, which some games
and homebrew actually care about -- without needing to make any more
changes to the other parts of the codebase, in addition to making
filesystem behaviour tests easier to write.
This adds a lightweight, easy to use std::variant wrapper intended to
be used as a return type for functions that can return either a result
or an error code.
Makes our libraries explicitly link in which libraries they need.
This makes our dependencies explicit and removes the reliance on the
LIBS variable to contain the libraries that they need.
This will create a merge conflict if two PRs try to increment the
cache version at the same time, which makes it noticeable that the
PR that gets merged last needs to increment the cache version again.
We already use this for savestates and the game list cache.
Regression from 1f1dae3.
This problem doesn't happen in DolphinWX as far as I know, but if
you've ran into the problem in DolphinQt2, it will carry over to
DolphinWX because of the shared game list cache.
