Add a function to calculate the magic constants required to optimize
signed 32-bit division.
Since this optimization is not exclusive to any particular architecture,
JitCommon seemed like a good place to put this.
Additionally, VCacheEnhance has been added to UVAT_group1. According to YAGCD, this field is always 1.
TVtxDesc also now has separate low and high fields whose hex values correspond with the proper registers, instead of having one 33-bit value. This change was made in a way that should be backwards-compatible.
Check return value of calls to File::CreateTempDir() from CoreTiming,
FileSystem, and MMIO test classes to verify the test user directory
exists, and fail the tests otherwise.
If the compiler can detect an issue with a format string at compile
time, then we should take advantage of that and turn the issue into a
hard compile-time error as such problems almost always lead to UB.
This helps with catching logging or assertion messages that have been
converted over to fmt but are still using the old, non-fmt variants
of the logging macros.
This commit also fixes all incorrect usages that I could find.
This fixes CreateFullPath to not create directories when it is known
that they already exist, instead of calling CreateDirectory anyway
and checking if the error is AlreadyExists. (That doesn't work
now that we have an accurate implementation of CreateDirectory
that performs permission checks before checking for existence.)
I'm not sure what I was thinking when I wrote that function.
Also adds some tests for CreateFullPath.
Files cannot be given a different file name, only moved across
directories.
Add a test for that behaviour and fix the existing
RenameWithExistingTargetFile test.
Test the behavior of OpArg::WriteRest by using MOV with the various
addressing modes (MatR, MRegSum, etc.) in the source operand.
Both the instruction and the instruction length are validated.
- Fixed a bug where pushing items over queue's size left it in a corrupted state
- For non-trivial types, have clear() and pop() run destructors
- Added emplace(args...)
- Added empty()
FixedSizeQueue has semantics of a circular buffer,
so pushing items continuously is expected to keep overwriting oldest elements gracefully.
Tests have been updated to verify correctness of a previously bugged behaviour
and to verify correctness of destructing non-trivial types
Since C++17, non-member std::size() is present in the standard library
which also operates on regular C arrays. Given that, we can just replace
usages of ArraySize with that where applicable.
In many cases, we can just change the actual C array ArraySize() was
called on into a std::array and just use its .size() member function
instead.
In some other cases, we can collapse the loops they were used in, into a
ranged-for loop, eliminating the need for en explicit bounds query.
This allows us to update the rich presence description if a channel
is launched from the Wii Menu. It also handles other PPC title
launches, e.g. Smash Bros. Masterpieces.
Host.h: Added Host_TitleChanged().
DolphinNoGUI/MainNoGUI.cpp: Implemented Host_TitleChanged().
DolphinQt/Host.cpp: Implemented Host_TitleChanged().
Android/jni/MainAndroid.cpp: Stubbed Host_TitleChanged().
DSPTool/StubHost.cpp: Stubbed Host_TitleChanged().
UnitTests/StubHost.cpp: Stubbed Host_TitleChanged().
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.
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.
As suggested here: https://dolp.in/pr7059#pullrequestreview-125401778
More descriptive than having a std::tuple of FS::Mode, and lets us
give names to known triplets of modes (like in ES). Functions that
only forward mode arguments are slightly less verbose now too.
Given this is actually a part of the Host interface, this should be
placed with it.
While we're at it, turn it into an enum class so that we don't dump its
contained values into the surrounding scope. We can also make
Host_Message take the enum type itself directly instead of taking a
general int value.
After this, it'll be trivial to divide out the rest of Common.h and
remove the header from the repository entirely
Also move it to MathUtils where it belongs with the rest of the
power-of-two functions. This gets rid of pollution of the current scope
of any translation unit with b<value> macros that aren't intended to be
used directly.
Given bit conversions between types are quite common in emulation
(particularly when it comes to floating-point among other things) it
makes sense to provide a utility function that keeps all the boilerplate
contained; especially considering it makes it harder to accidentally
misuse std::memcpy (such as accidentally transposing arguments, etc).
Another benefit of this function is that it doesn't require separating
declarations from assignments, allowing variables to be declared const.
This makes the scenario of of uninitialized variables being used less
likely to occur.
The existing backend did not handle cases where the target exists
correctly.
This is a bug that has been around forever but was only recently
exposed when ES started to use our FS code.
Also adds some unit tests to make sure this won't get broken again.
Keeps all of the floating-point utility functions in their own file to
keep them all together. This also provides a place for other
general-purpose floating-point functions to be added in the future,
which will be necessary when improving the flag-setting within the
interpreter.
This adds unit tests for the Wii filesystem now that the filesystem
interface is neatly separated from the IPC code.
Basic FS functionality is tested, in addition to problematic usages and
edge cases that Dolphin used to handle incorrectly (which of course
broke emulated software).
These tests should make it quite a bit harder to introduce regressions.
Issues that are covered by the tests in particular:
* Metadata: issue 10234 (though tests are commented out for now because
Dolphin doesn't support NAND images yet so it can't track metadata);
* EOF seeks/reads: https://github.com/dolphin-emu/dolphin/pull/4942
* Read/write operations from multiple handles: see issue 2917, 5232 and
8702 and https://github.com/dolphin-emu/dolphin/pull/2649
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.
Since all queues are FIFO data structures, the name wasn't informative
as to why you'd use it over a normal queue. I originally thought it had
something to do with the hardware graphics FIFO.
This renames it using the common acronym SPSC, which stands for
single-producer single-consumer, and is most commonly used to talk about
lock-free data structures, both of which this is.
I don't know who thought it would be a good idea to put the Wiimote
connect code as part of the Host interface, and have that called
from both the UI code and the core. And then hack around it by having
"force connect" events whenever Host_ConnectWiimote is called
from the core...
Showing the Wii remote connection status leads to inconsistent UX,
because we don't do anything like that for GameCube controllers
or with Bluetooth passthrough.
It's also questionable how useful it is given that:
* it doesn't print the number of connected remotes, just that one
remote is connected, connecting or not connected, so the only info
it provides is actually wrong when using multiple remotes;
* this user-facing feature is actually broken in master and no one has
complained AFAIK, which means people don't really rely on it;
* the status bar isn't visible most of the time unless the user is
using render to main or deliberately keeping the main window's
status bar visible by moving the render window and they're not too
far away from their screen;
* emulated Wii remotes now reconnect on input, which means that there
is less of a need to actually know at all times whether a remote
is connected, since pressing any button will reconnect it and provide
immediate, visible feedback via OSD messages and the Wii remote
pointer appearing.
This one verifies bitmasks where low bits are set to 1 (hence the name).
Any stray 0 among the lower ones or any stray 1 among the higher zeros
renders the mask invalid.
The edge cases of all zeros and all ones are considered valid masks.
It uses an efficient implementation. It's the counterpart of

- Moves all test code from DSPTool into UnitTests/Core/DSPAssemblyTest.
- Converts test files (which could only be loaded if they were in the
shell's working directory, so basically never) into C++ values.
- Enables most of the commented-out tests.
- Removes non-deterministic random code test.
The current prefixing makes it harder to build test executables directly
from the command line, since the target name breaks CMake convention and
doesn't match the name passed to `add_dolphin_test`. They all have "Test"
somewhere in the name anyways.
This adds unit tests for IOS/ESFormats, and in particular, for the
TMDReader. It is tested using invalid TMDs (to check IsValid()) and
two valid, properly signed TMDs.
Things which are now tested:
* Title type helper functions.
* TMDReader: Validity check.
* TMDReader: General information returned by the Get*() methods.
* TMDReader: Raw TMD and generated TMD view, compared against IOS.
* TMDReader: Game ID generation code (which is Dolphin specific).
* TMDReader: Content information: getting by ID/index, order, metadata.

This moves all the byte swapping utilities into a header named Swap.h.
A dedicated header is much more preferable here due to the size of the
code itself. In general usage throughout the codebase, CommonFuncs.h was
generally only included for these functions anyway. These being in their
own header avoids dumping the lesser used utilities into scope. As well
as providing a localized area for more utilities related to byte
swapping in the future (should they be needed). This also makes it nicer
to identify which files depend on the byte swapping utilities in
particular.
Since this is a completely new header, moving the code uncovered a few
indirect includes, as well as making some other inclusions unnecessary.
This attempts to make some bit arithmetic more self-documenting and also
make it easier during review to identify potential off-by-one errors by
making it possible to just specify which bits are being extracted.
Functions both support the case where bits being extracted can vary and
fixed bit extraction. In the case the bits are fixed, compile-time asserts
are present to prevent accidental API usage at compile-time.
e.g. Instead of shifting and masking to get bits 10 to 15,
Common::ExtractBits<10, 15>(value) can just be done instead.
