Now that clang-format makes [[nodiscard]] attributes format sensibly, we
can apply them to several functions within the common library to allow
the compiler to complain about any misuses of the functions.
This makes it more inline with its currently unavailable standardized
analogue std::derived_from.
While we're at it, we can also make the template match the requirements
of the standardized variant as well.
Previously the constructor for all of these would run at program
startup, consuming time before the application can enter main().
This is also particularly dangerous, given the logging system wouldn't
have been initialized properly yet, yet the program would use the logs
to signify an error.
To rectify this, we can replace the literals with constexpr functions
that perform the conversion at compile-time, completely eliminating the
runtime cost of initializing these arrays.
- In `SetCurrentThreadName`, when on Linux, truncate to 15 bytes, as (at
least on glibc) `pthread_set_name_np` will otherwise return `ERANGE` and
do nothing.
- Also, add logging in case `pthread_set_name_np` returns an error
anyway. This is Linux-specific, as the Apple and BSD versions of
`pthread_set_name_np return `void`.
- Change the name for CPU threads in multi-core mode from
"yuzu:CoreCPUThread_N" (19 bytes) to "yuzu:CPUCore_N" (14 bytes) so it
fits into the Linux limit. Some other thread names are also cut off,
but I didn't bother addressing them as you can guess them from the
truncated versions. For a CPU thread, truncation means you can't see
which core it is!
On DragonFly and NetBSD build fails with

* ipc: Allow all trivially copyable objects to be passed directly into WriteBuffer
With the support of C++20, we can use concepts to deduce if a type is an STL container or not.
* More agressive concept for stl containers
* Add -fconcepts
* Move to common namespace
* Add Common::IsBaseOf

In cases where the size is not a known constant when inlining, AlignUp<std::size_t> currently generates two 64-bit div instructions.
This generates one div and a cmov which is significantly cheaper.
This is a new attempt at #4206 that shouldn't break windows builds.
If someone else could test on windows, it would be much appreciated.
Previously, the build bot passed but the actual builds failed.
On gcc/ld, and clang/lld, fmt::v6 symbols are excluded, so linking
fails. This fixes the issue.
Note: This was included in the FindBoost changes I shared with
BlinkHawk, however only they were merged. I'm not sure if it was missed,
or if there was an issue with this part of the change.
This commit: Implements CPU Interrupts, Replaces Cycle Timing for Host
Timing, Reworks the Kernel's Scheduler, Introduce Idle State and
Suspended State, Recreates the bootmanager, Initializes Multicore
system.
Emit code compatible with NV_gpu_program5.
This should emit code compatible with Fermi, but it wasn't tested on
that architecture. Pascal has some issues not present on Turing GPUs.
* Remove git submodules that will be loaded through conan
* Move custom Find modules to their own folder
* Use conan for downloading missing external dependencies
* CI: Change the yuzu source folder user to the user that the containers run on
* Attempt to remove dirty mingw build hack
* Install conan on the msvc build
* Only set release build type when using not using multi config generator
* Re-add qt bundled to workaround an issue with conan qt not downloading prebuilt binaries
* Add workaround for submodules that use legacy CMAKE variables
* Re-add USE_BUNDLED_QT on the msvc build bot
It's undefined behavior to pass a null pointer to std::fread and
std::fwrite, even if the length passed in is zero, so we must perform
the precondition checking ourselves.
A common case where this can occur is when passing in the data of an
empty std::vector and size, as an empty vector will typically have a
null internal buffer.
While we're at it, we can move the implementation out of line and add
debug checks against passing in nullptr to std::fread and std::fwrite.
On Windows, network shares use paths like \\server\share\file which were
being broken by FileUtil::SanitizePath() removing double slashes.
Changed the code in SanitizePath to permit a double-backslash if it
occurs at the start of a filepath (on Windows only).
* IOFile: Make the move constructor and move assignment operator noexcept
Certain parts of the standard library try to determine whether or not a
transfer operation should either be a copy or a move. The prevalent notion
of move constructors/assignment operators is that they should not throw,
they simply move an already existing resource somewhere else.
This is typically done with 'std::move_if_noexcept'. Like the name says,
if a type's move constructor is noexcept, then the functions retrieves an
r-value reference (for move semantics), or an l-value (for copy semantics)
if it is not noexcept.
As IOFile deletes the copy constructor and copy assignment operators,
using IOFile with certain parts of the standard library can fail in
unexcepted ways (especially when used with various container
implementations). This prevents that.
* fix various instances of -1 being assigned to unsigned types
* do not assign in conditional statements
* File/IOFile: Check _tfopen_s properly
* common/file_util.cpp: address review comments

This PR aims to reduce the memory usage in the CPU page table by moving
GPU specific parameters into a child class. This saves 1Gb of Memory for
most games.
