[dynarmic] Coalesce non-exclusive Write/Read fallback functions (#4158)

2026-09-18T23:39:46+00:00

the general idea is to have a common procedure form whom to call this way theres less "jumping around" for values of different sizes additionally this **should** allow for better codegen since most of the u8,u16,u32,u64 can be held within a u64 theoretically this means that you could deifne callbacks in suck a way that it's essentially as costly as a `mov r64, m64` but that's not doable due to the fact we have to do translations... Is this a good change? Primarily aimed for x86 and ARM to benefit, but I suppose LooooooongArch64 can benefit too.

[macos, dynarmic] Implement VectorMin/Max{S,U}64 emitters (Apple Silicon fix) (#3421)

2026-05-03T02:29:49+00:00

[macos] dynarmic: Implement VectorMin/Max{S,U}64 emitters (Apple Silicon fix) Implements the missing A64 backend emitters for VectorMinS64, VectorMinU64, VectorMaxS64, and VectorMaxU64. These IR opcodes are generated by the optimizer but lack direct hardware instruction support for 64-bit elements in the base NEON set (e.g., UMIN.2D does not exist). They are implemented using a compare (CMGT/CMHI) followed by a bitwise select (BSL). This correctly selects between the two source registers, whereas using BIT would incorrectly zero out elements. This implementation is guarded by #ifdef __APPLE__ to ensure no impact on other platforms. Unit tests could not be added to a64.cpp because UMIN.2D is not a valid A64 instruction, causing the assembler (Oaknut) to reject it. The fix was verified by running Team Sonic Racing, which previously crashed on this synthetic opcode. Fixes crash in Team Sonic Racing on macOS.

[dynarmic] implement missing SSE3 implementations (#3301)

2026-03-31T00:53:51+00:00

Implementations for SSE3 CPUs (prescott) Instead of fixing some of the bugs with HostCall when paired with vectors, i'll simply remove as many host calls as I can within the most used vector instructions - then just minimize their usage to memory read/writes. Emitting the raw assembly code is faster than doing a HostCall, HostCalls are VERY expensive. So this is the desired output anyways.
