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.
Some of the classes in this file already do this, so we can apply this
to the other ones to be consistent.
Allows these classes to play nicely and not churn copies when used with
standard containers or any other API that makes use of
std::move_if_noexcept.

We can adjust the API to allow std::size_t indices, which simplifies
operating with standard container types. It also prevents truncation
warnings from occurring in these cases as well.
* archive: Make use of std::pair for OpenFileFromArchive
The tuple only makes use of two elements, so we can use a pair to
simplify the number of underlying template instantiations that need to
be done, while also simplifying the surrounding code.
* archive: Simplify MakeResult calls
MakeResult can deduce the contained result type based off the type of
the variable being passed to it, so explicitly specifying it is a little
verbose.
* Avoid deadlock when stopping video dumping
* Use static_cast, make quit atomic
* One more atomic load
* Use suggested lock instead of atomic
* Fix locking
While we're at it, we can also improve some of the allocations and
copying that would be going on in one case by preallocating and then
emplacing before modifying.
I'm not sure why we decided to have a boolean here, but apparently that wasn't the correct behaviour. According to HW tests, the Software Keyboard simply displays the default text when the button text provided is empty (**not necessarily all zero**). For example, if you set a text for one of the buttons and leave others empty, the button you set will have your text, while others will have their default texts. Removed the boolean and updated frontend code to make it correct.
* gl_rasterizer_cache: Mark file-scope functions as static where applicable
Prevents -Wmissing-declaration warnings from occurring and also makes
these functions internally linked.
* gl_rasterizer_cache: Remove unused local std::string variable
Despite being unused, compilers are unable to completely remove any code
gen related to the construction and destruction of this variable, since
the destructor of std::string is non-trivial.
Thus, we can remove it to reduce a minor amount of unnecessary code
generation
* gl_rasterizer_cache: Mark hash implementation as noexcept
This shouldn't throw.
* gl_rasterizer_cache: Remove unused variable in ClearAll()
* gl_rasterizer_cache: Make use of const on references explicit
While declared as auto&, these actually behave as const auto& variables,
due to the constness of the container being iterated. We can make this
explicit for readability sake.
* gl_rasterizer_cache: Resolve truncation warnings
The size is forwarded to a std::memset call, which takes a std::size_t
as its size parameter, so we can just make this change to silence the
warnings.
* gl_rasterizer_cache: Resolve variable shadowing warnings
Prevents a -Wshadow warning from occurring.

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.
Prevents the internal buffer in the std::optional from being zeroed out
unnecessarily and instead sets the validity byte only in some
implementations.
While we're at it, we can make use of std::move to eliminate unnecessary
heap reallocations from occurring.
Allows us to avoid even more string churn by allowing the AddLine
function to make use of fmt formatting so the string is formatted all at
once instead of concatenating multiple strings.
This is similar to how yuzu's decompiler works, which I've made function
the same way in the past.
Quite a few service functions are stubbed but still pop all their
arguments, which can lead to unused variable warnings.
We can mark the unused arguments with [[maybe_unused]] to silence these
warnings until a full implementation of these functions are made.
Allows implementations to allocate the object and the shared_ptr control
block in one allocation instead of needing to do two separate
allocations.
Also looks much nicer to the reader.
* swkbd: Fix a bug where clicking Cancel hangs the game
The text is validated in `Finalize`. If the validation fails, an error is returned and the applet is not actually finalized. This can result in hangs.
This is usually not a problem as the frontend is expected to validate the text passed to `Finalize`. However, when the user clicked on `Cancel`, the text is ignored and the frontend won't do any validation. Therefore, we should skip the validation here as well.
Also fixed a potential data race. All these functions should now be called on the same thread
* Address review comments
Renamed the fields
Remove close button
This class is memcpy-ed and memcpy has the requirement that data passed
to it must be trivially copyable, otherwise the behavior is undefined.
This is trivial to resolve as BitField was made trivially copyable a
while ago, so this explicit copy assignment operator isn't necessary.
This can be removed as it's not used. Even if it were however, it would
be an incorrect forward declaration, as ServiceManager exists within the
Service::SM namespace, not the top-level SM namespace.
Same behavior, no heap allocation.
strings returned from glGetString() are guaranteed to be static strings,
so this is safe to do. They're also guaranteed to be null-terminated.
Some implementations can use the std::nullopt_t constructor of
std::optional to avoid needing to completely zero out the internal
buffer of the optional and instead only set the validity byte within it.
e.g. Consider the following function:
std::optional<std::vector<ShaderDiskCacheRaw>> fn() {
return {};
}
With libc++ this will result in the following code generation on x86-64:
Fn():
mov rax, rdi
vxorps xmm0, xmm0, xmm0
vmovups ymmword ptr [rdi], ymm0
vzeroupper
ret
With libstdc++, we also get the similar equivalent:
Fn():
vpxor xmm0, xmm0, xmm0
mov rax, rdi
vmovdqu XMMWORD PTR [rdi], xmm0
vmovdqu XMMWORD PTR [rdi+16], xmm0
ret
If we change this function to return std::nullopt instead, then this
simplifies both the code gen from libc++ and libstdc++ down to:
Fn():
mov BYTE PTR [rdi+24], 0
mov rax, rdi
ret
Given how little of a change is necessary to result in better code
generation, this is essentially a "free" very minor optimization.
Previously, we were returning a value that was way too big, causing an integer overflow in Fractured Souls.
According to wwylele, the biggest oberserved save size for 3DS is 1MB, so this new value should leave plenty of room, even if games use a bigger size.
Many of these functions are capable of being used within const contexts,
so we can apply the const qualifier in some cases and add const based
overloads for others, which makes the interface a little bit more
flexible and const-correct.
* core/memory: Amend unusual return value of operator=
operator= usually returns a reference to this. Given there's no comment
explaining why void was used, this can be assumed to be an oversight.
* core/memory: Make use of std::move in Entry::operator=
Same behavior, minus the need for an atomic reference count increment
and decrement (since MemoryRef contains a std::shared_ptr).
* ArmInterface: return ref instead of copy for GetTimer
* ArmInterface: add const ref GetTimer
* ArmInterface: return raw pointer instead of shared_ptr in GetTimer
* remove more unnecessary shared_ptr usage
* Fix save states
* fix unit tests
