Fixes and workarounds to make UBSan happier on macOS

2023-07-15T19:00:28+00:00

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.

code: dodge PAGE_SIZE #define

2022-08-19T23:08:40+00:00

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
