ARM64– refers to the 64-bit ARM architecture (AArch64). There's no such thing as WoA64. Finally, when referring to data types, the following definitions from ARM are referenced: Short-Vector– A data type directly representable in SIMD, a vector of 8 bytes or 16 bytes worth of elemen...

Integer type values are returned in r0, optionally extended to r1 for 64-bit return values. VFP/NEON floating-point or SIMD type values are returned in s0, d0, or q0, as appropriate. Stack The stack must always remain 4-byte aligned, and must be 8-byte aligned at any function boundary...
² AArch64’s register 31 is similar to PowerPC’s register 0, whichchanges meaning depending on the instruction. In PowerPC assembly, it was on you to keep track of which encodings treat register 0 as a value register, and which treat it as a zero register. At least AArch64 express...
stack, and the translator might not try to infer that a stack push is passing an argument and translate it into a load-into-register), meaning it'd be more work to have a translated x86-64 binary, using the ARM64EC ABI, call a routine in a native ARM64 DLL, using the ARM64 ABI...
