| * Fixes and workarounds to make UBSan happier on macOScomex2023-07-151-13/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are still some other issues not addressed here, but it's a start. Workarounds for false-positive reports: - `RasterizerAccelerated`: Put a gigantic array behind a `unique_ptr`, because UBSan has a [hardcoded limit](https://stackoverflow.com/questions/64531383/c-runtime-error-using-fsanitize-undefined-object-has-a-possibly-invalid-vp) of how big it thinks objects can be, specifically when dealing with offset-to-top values used with multiple inheritance. Hopefully this doesn't have a performance impact. - `QueryCacheBase::QueryCacheBase`: Avoid an operation that UBSan thinks is UB even though it at least arguably isn't. See the link in the comment for more information. Fixes for correct reports: - `PageTable`, `Memory`: Use `uintptr_t` values instead of pointers to avoid UB from pointer overflow (when pointer arithmetic wraps around the address space). - `KScheduler::Reload`: `thread->GetOwnerProcess()` can be `nullptr`; avoid calling methods on it in this case. (The existing code returns a garbage reference to a field, which is then passed into `LoadWatchpointArray`, and apparently it's never used, so it's harmless in practice but still triggers UBSan.) - `KAutoObject::Close`: This function calls `this->Destroy()`, which overwrites the beginning of the object with junk (specifically a free list pointer). Then it calls `this->UnregisterWithKernel()`. UBSan complains about a type mismatch because the vtable has been overwritten, and I believe this is indeed UB. `UnregisterWithKernel` also loads `m_kernel` from the 'freed' object, which seems to be technically safe (the overwriting doesn't extend as far as that field), but seems dubious. Switch to a `static` method and load `m_kernel` in advance.

| | | | | | | | | | | | | | | | | | | | | Some header files, specifically for OSX and Musl libc define PAGE_SIZE to be a number This is great except in yuzu we're using PAGE_SIZE as a variable Specific example `static constexpr u64 PAGE_SIZE = u64(1) << PAGE_BITS;` PAGE_SIZE PAGE_BITS PAGE_MASK are all similar variables. Simply deleted the underscores, and then added YUZU_ prefix Might be worth noting that there are multiple uses in different classes/namespaces This list may not be exhaustive Core::Memory 12 bits (4096) QueryCacheBase 12 bits ShaderCache 14 bits (16384) TextureCache 20 bits (1048576, or 1MB) Fixes #8779
* chore: make yuzu REUSE compliantAndrea Pappacoda2022-07-271-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [REUSE] is a specification that aims at making file copyright information consistent, so that it can be both human and machine readable. It basically requires that all files have a header containing copyright and licensing information. When this isn't possible, like when dealing with binary assets, generated files or embedded third-party dependencies, it is permitted to insert copyright information in the `.reuse/dep5` file. Oh, and it also requires that all the licenses used in the project are present in the `LICENSES` folder, that's why the diff is so huge. This can be done automatically with `reuse download --all`. The `reuse` tool also contains a handy subcommand that analyzes the project and tells whether or not the project is (still) compliant, `reuse lint`. Following REUSE has a few advantages over the current approach: - Copyright information is easy to access for users / downstream - Files like `dist/license.md` do not need to exist anymore, as `.reuse/dep5` is used instead - `reuse lint` makes it easy to ensure that copyright information of files like binary assets / images is always accurate and up to date To add copyright information of files that didn't have it I looked up who committed what and when, for each file. As yuzu contributors do not have to sign a CLA or similar I couldn't assume that copyright ownership was of the "yuzu Emulator Project", so I used the name and/or email of the commit author instead.
