2022-09-09Implement VRSRA, VRSHRN, VQSHRUN, VQMOVN, VQMOVUN, VQADD, VQSUB, VRHADD, ↵gdkchan
VPADDL, VSUBL, VQDMULH and VMLAL Arm32 NEON instructions (#3677) * Implement VRSRA, VRSHRN, VQSHRUN, VQMOVN, VQMOVUN, VQADD, VQSUB, VRHADD, VPADDL, VSUBL, VQDMULH and VMLAL Arm32 NEON instructions * PPTC version * Fix VQADD/VQSUB * Improve MRC/MCR handling and exception messages In case data is being recompiled as code, we don't want to throw at emit stage, instead we should only throw if it actually tries to execute
2022-09-08Clean up rejit queue (#2751)FICTURE7
2022-09-08Implemented in IR the managed methods of the Saturating region ... (#3665)LDj3SNuD
* Implemented in IR the managed methods of the Saturating region ... ... of the SoftFallback class (the SatQ ones). The need to natively manage the Fpcr and Fpsr system registers is still a fact. Contributes to https://github.com/Ryujinx/Ryujinx/issues/2917 ; I will open another PR to implement in Intrinsics-branchless the methods of the Saturation region as well (the SatXXXToXXX ones). All instructions involved have been tested locally in both release and debug modes, in both lowcq and highcq. * Ptc.InternalVersion = 3665 * Addressed PR feedback.

2022-08-14PreAllocator: Check if instruction supports a Vex prefix in ↵merry

2022-08-05Implement Arm32 Sha256 and MRS Rd, CPSR instructions (#3544)gdkchan
* Implement Arm32 Sha256 and MRS Rd, CPSR instructions * Add tests using Arm64 outputs
2022-07-29Move partial unmap handler to the native signal handler (#3437)riperiperi
* Initial commit with a lot of testing stuff. * Partial Unmap Cleanup Part 1 * Fix some minor issues, hopefully windows tests. * Disable partial unmap tests on macos for now Weird issue. * Goodbye magic number * Add COMPlus_EnableAlternateStackCheck for tests `COMPlus_EnableAlternateStackCheck` is needed for NullReferenceException handling to work on linux after registering the signal handler, due to how dotnet registers its own signal handler. * Address some feedback * Force retry when memory is mapped in memory tracking This case existed before, but returning `false` no longer retries, so it would crash immediately after unprotecting the memory... Now, we return `true` to deliberately retry. This case existed before (was just broken by this change) and I don't really want to look into fixing the issue right now. Technically, this means that on guest code partial unmaps will retry _due to this_ rather than hitting the handler. I don't expect this to cause any issues. This should fix random crashes in Xenoblade Chronicles 2. * Use IsRangeMapped * Suppress MockMemoryManager.UnmapEvent warning This event is not signalled by the mock memory manager. * Remove 4kb mapping
2022-07-06Implement CPU FCVT Half <-> Double conversion variants (#3439)gdkchan
* Half <-> Double conversion support * Add tests, fast path and deduplicate SoftFloat code * PPTC version
2022-06-05Extend uses count from ushort to uint on Operand Data structure (#3374)gdkchan
2022-05-31Refactor CPU interface to allow the implementation of other CPU emulators ↵gdkchan
(#3362) * Refactor CPU interface * Use IExecutionContext interface on SVC handler, change how CPU interrupts invokes the handlers * Make CpuEngine take a ITickSource rather than returning one The previous implementation had the scenario where the CPU engine had to implement the tick source in mind, like for example, when we have a hypervisor and the game can read CNTPCT on the host directly. However given that we need to do conversion due to different frequencies anyway, it's not worth it. It's better to just let the user pass the tick source and redirect any reads to CNTPCT to the user tick source * XML docs for the public interfaces * PPTC invalidation due to NativeInterface function name changes * Fix build of the CPU tests * PR feedback
2022-05-02Support memory aliasing (#2954)gdkchan
* Back to the origins: Make memory manager take guest PA rather than host address once again * Direct mapping with alias support on Windows * Fixes and remove more of the emulated shared memory * Linux support * Make shared and transfer memory not depend on SharedMemoryStorage * More efficient view mapping on Windows (no more restricted to 4KB pages at a time) * Handle potential access violations caused by partial unmap * Implement host mapping using shared memory on Linux * Add new GetPhysicalAddressChecked method, used to ensure the virtual address is mapped before address translation Also align GetRef behaviour with software memory manager * We don't need a mirrorable memory block for software memory manager mode * Disable memory aliasing tests while we don't have shared memory support on Mac * Shared memory & SIGBUS handler for macOS * Fix typo + nits + re-enable memory tests * Set MAP_JIT_DARWIN on x86 Mac too * Add back the address space mirror * Only set MAP_JIT_DARWIN if we are mapping as executable * Disable aliasing tests again (still fails on Mac) * Fix UnmapView4KB (by not casting size to int) * Use ref counting on memory blocks to delay closing the shared memory handle until all blocks using it are disposed * Address PR feedback * Make RO hold a reference to the guest process memory manager to avoid early disposal Co-authored-by: nastys <nastys@users.noreply.github.com>

2021-10-18Add an early `TailMerge` pass (#2721)FICTURE7
* Add an early `TailMerge` pass Some translations can have a lot of guest calls and since for each guest call there is a call guard which may return. This can produce a lot of epilogue code for returns. This pass merges the epilogue into a single block. ``` Using filter 'hcq'. Using metric 'code size'.
