When the vector is empty, using `&vec[0]` involves undefined behaviour. While that works fine most of the time, Flatpak builds aborted on a failed `__builtin_expect`.
I searched for such occurences across the codebase with the regex `(?<!&)&\w+\[0\]` and fixed those that would potentially cause issues.
Only enabled for NCCHs that do not have an override romfs.
LayeredFS files should be put in the `load` directory in User Directory. The directory structure is similar to yuzu's but currently does not allow named mods yet. Replacement files should be put in `load/mods/<Title ID>/romfs` while patches/stubs should be put in `load/mods/<Title ID>/romfs_ext`.
This changes ApplyCodePatch to return a ResultStatus, which makes it
possible to determine whether patch applying has failed. Previously,
only a boolean was returned, and false was returned when no patch
was found OR when a patch was found but applying it failed.
This also changes AppLoader_NCCH to return an error if patching fails
because the executable is likely to be left in an inconsistent state
and we should not proceed booting in that case.
This allows an IPS patch to edit .bss. This is useful for game patches
that need to add code, as putting things in .bss allows adding new code
*without* editing .code and thus without having to relocate everything.
* common/thread: Remove unused functions
Many of these functions are carried over from Dolphin (where they aren't
used anymore). Given these have no use (and we really shouldn't be
screwing around with OS-specific thread scheduler handling from the
emulator, these can be removed.
The function for setting the thread name is left, however, since it can
have debugging utility usages.
* input_common/sdl: Use a type alias to shorten declaration of GetPollers
Just makes the definitions a little bit more tidy.
* input_common/sdl: Correct return values within implementations of GetPollers()
In both cases, we weren't actually returning anything, which is
undefined behavior.
* yuzu/debugger/graphics_surface: Fill in missing surface format listings
Fills in the missing surface types that were marked as unknown. The
order corresponds with the TextureFormat enum within
video_core/texture.h.
We also don't need to all of these strings as translatable (only the
first string, as it's an English word).
* yuzu/debugger/graphics_surface: Clean up connection overload deduction
We can utilize qOverload with the signal connections to make the
function deducing a little less ugly.
* yuzu/debugger/graphics_surface: Tidy up SaveSurface
- Use QStringLiteral where applicable.
- Use const where applicable
- Remove unnecessary precondition check (we already assert the pixbuf
being non null)
* yuzu/debugger/graphics_surface: Display error messages for file I/O errors
* core: Add missing override specifiers where applicable
Applies the override specifier where applicable. In the case of
destructors that are defaulted in their definition, they can
simply be removed.
This also removes the unnecessary inclusions being done in audin_u and
audrec_u, given their close proximity.
* kernel/thread: Make parameter of GetWaitObjectIndex() const qualified
The pointed to member is never actually modified, so it can be made
const.
* kernel/thread: Avoid sign conversion within GetCommandBufferAddress()
Previously this was performing a u64 + int sign conversion. When dealing
with addresses, we should generally be keeping the arithmetic in the
same signedness type.
This also gets rid of the static lifetime of the constant, as there's no
need to make a trivial type like this potentially live for the entire
duration of the program.
* kernel/codeset: Make CodeSet's memory data member a regular std::vector
The use of a shared_ptr is an implementation detail of the VMManager
itself when mapping memory. Because of that, we shouldn't require all
users of the CodeSet to have to allocate the shared_ptr ahead of time.
It's intended that CodeSet simply pass in the required direct data, and
that the memory manager takes care of it from that point on.
This means we just do the shared pointer allocation in a single place,
when loading modules, as opposed to in each loader.
* kernel/wait_object: Make ShouldWait() take thread members by pointer-to-const
Given this is intended as a querying function, it doesn't make sense to
allow the implementer to modify the state of the given thread.
Using member variables for referencing the segments array increases the
size of the class in memory for little benefit. The same behavior can be
achieved through the use of accessors that just return the relevant
segment.
General moving to keep kernel object types separate from the direct
kernel code. Also essentially a preliminary cleanup before eliminating
global kernel state in the kernel code.
Previously for installed titles, the file type would be NCCH (assumed as CXI) and the extension would be ".app". This would trigger a warning of the file "having a different type than its extension", which is actually not true here.
