It's not common code that could be reused for, say, Citra;
it's absolutely specific to Wii emulation and only used by the Dolphin
core, so let's move it there.
Another reason for doing this is to avoid having Common depend on Core.
It was discovered that some titles rely on filesystem metadata to work
properly. Currently, in master they either simply won't find their
save files (for example Bolt) or will complain about the Wii system
memory being corrupted (on first use or every time depending on
the title).
In order to even be able to keep track of file metadata, we first need
to eliminate all direct accesses to the NAND and make all kinds of
operations go through the filesystem code added in PR 6421.
This commit starts the migration process by making SysConf use
the new FS interface.
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
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
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.
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.
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.
The SGI extension does not define calling SwapInterval with a parameter
of zero as valid. It was just lucky that drivers interpreted this as
vsync off. The EXT_swap_control extension defines zero as a valid value.
Mesa does not appear to support the EXT variant, so we fall back to
MESA_swap_control here, which also supports zero.
This fix the awkwardness of having the symbols detection, parsing and loading related logs be in OS HLE while they don't have anything to do with that.
These are only used internally. This also allows us to eliminate some
symbols that get dumped into the exposed Gen namespace.
By extension this also hides the Write[X] functions from OpArg's public
interface. This is only used internally by XEmitter, so they shouldn't
be usable by anything else.
This replaces usages of the non-standard __FUNCTION__ macro with the standard
mandated __func__ identifier.
__FUNCTION__ is a preprocessor definition that is provided as an
extension by compilers. This was the only convenient option to rely on
pre-C++11. However, C++11 and greater mandate the predefined identifier
__func__, which lets us accomplish the same thing.
The difference between the two, however, is that __func__ isn't a
preprocessor macro, it's an actual identifier that exists at function
scope. The C++17 draft standard (N4659) at section [dcl.fct.def.general]
paragraph 8 states:
"
The function-local predefined variable __func__ is defined as if a
definition of the form
static const char __func__[] = "function-name ";
had been provided, where function-name is an implementation-defined
string. It is unspecified whether such
a variable has an address distinct from that of any other object in the
program.
"
Thankfully, we don't do any macro or string concatenation with __FUNCTION__
that can't be modified to use __func__.
Some locales use non-breaking spaces as separators, so getting the
encoding right is important. If DolphinWX gets a string that isn't
valid UTF-8, it flat out won't display the string.
There is code below that assumes the presence of those macros (by #undef'ing them), but none of the included headers provided them.
This fixes a build failure on OpenBSD where the undef'd macros _do_ get picked up later on in a compilation unit (through which include, I don't know), and thus shadow the Common::swap* functions.
Trying to force the XSI version by undefining _GNU_SOURCE can lead
to compilation errors on some systems because of headers expecting
that _GNU_SOURCE is defined.
This commit uses define checks to detect which version we have.
I tried making an overloaded function (int and const char*) instead,
but that led to a warning about one of the variants being unused.
The PC offset ADRP() path takes a s32 value, but the input offset was
being tested as abs(ptr) < 0xFFFFFFFF. This caused values between
0x80000000 and 0xFFFFFFFF to incorrectly use this path, despite the
offsets not being representable in an s32.
This caused a crash in the VertexLoader on android 8.1 immediate in wind
waker (and possibly all other apps on android 8.1) as the jit and data
sections happened to be loaded 4gb apart in virtual memory, causing some
pointers to hit this
These three instructions use the B field (bits 16-20 of the opcode)
to determine what the operand register is. However, the code was
using the path that uses the C field (bits 21-25).
This amends the code to use the B field (and also fixes the 64-bit PPC
opcodes, because why not?).
Fixes issue 10683.
Currently, a simple typo in the system name will trigger an assert
message that complains about a "programming error". This is not
user friendly and misleading.
So this changes GetSystemFromName to return an std::optional, which
allows for callers to check whether the system exists and handle
failures better.
Originally, Layer contained a std::map of Sections, which containted a std::map
containing the (key, value) pairs. Here we flattern this structure so that only
one std::map is required, reducing the number of indirections required and
vastly simplifying the code.
No code is relying on this unexplained null byte check, since
the only code that calls UTF16ToUTF8 on non-Windows systems
is UTF16BEToUTF8, which explicitly strips null bytes.
The earlier code always tried to use TitleDatabase for getting
title names, but that didn't work for disc-based games, because
there was no way to get the maker ID.
Fixes a regression which broke running several Dolphin instances at the
same time on Windows. Thanks to exjam for spotting the issue
pretty much immediately. Sorry about that!
Also changes the file names to be more consistent on all platforms.
Assign a name to the CreateFileMapping handle on Win32 so third party
applications can read from Dolphin's memory and integrate with the
current emulation.
Built and tested, multiple sessions are still possible without
collisions.
Ideally Common.h wouldn't be a header in the Common library, and instead be renamed to something else, like PlatformCompatibility.h or something, but even then, there's still some things in the header that don't really fall under that label
This moves the version strings out to their own version header that doesn't dump a bunch of other unrelated things into scope, like what Common.h was doing.
This also places them into the Common namespace, as opposed to letting them sit in the global namespace.
CNTVCT_EL0 is force-enabled on all linux plattforms.
Windows is untested, but as this is the best way to get *any* low
overhead performance counters, they likely use it as well.
This apparently fixes https://bugs.dolphin-emu.org/issues/10499 somehow.
The first changed line of this commit is just for performance - the
second changed line is where the difference in behavior is.
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.
