Wunkolo c6a7270a06 [a64] Fix external function call arguments

Wunkolo 49f9edbfab [a64] Reorganize guest register allocation

2024-06-23 14:00:24 -07:00
Wunkolo 0f9769baac [a64] Refactor `REV{16,32}` to `REV`
Derive the reversal-size from the register-size.
REV32 is also the wrong one to be using here since it will reverse the bytes of upper and lower 32-bit words.
2024-06-23 14:00:24 -07:00
Wunkolo 52b259369e [a64] Fix `ComputeMemoryAddress{Offset}` register stomp
`W1` is a possible HIR register allocation and using W1 here was stomping over it. Don't use W1, use the provided "scratch" register.

Let the register type determine the reverse-size

REV32 was also the wrong instruction to use.

Wunkolo 2b3147b2ed [a64] Fix `CallIndirect` return address
Should be `GUEST_RET_ADDR` not `GUEST_CALL_RET_ADDR`.
2024-06-23 14:00:23 -07:00
Wunkolo 8b4b713e0e [a64] Remove redundant zero-extension during address computation

Wunkolo 9b70ea07ef [a64] Draft Windows-ARM64 stack unwinding data
Things still get weird at the thunks, but this allows for callstacks between-to-guest calls
2024-06-23 14:00:23 -07:00
Wunkolo a1741bf609 [a64] Pad code cache with `0x00` bytes 2024-06-23 14:00:23 -07:00
Wunkolo dfa5bdbafb [a64] Fix ResolveFunctionThunk call
Resolving the function puts it into X0 and should be called immediately after.

We were just calling ResolveFunction on ResolveFunction recursively
2024-06-23 14:00:23 -07:00
Wunkolo 65288d5796 [a64] Fix resetting of labels during Emplace
On the x64 side, this is the same as the `reset()` function resetting the label-manager
2024-06-23 14:00:23 -07:00
Wunkolo 5b8ac36aa6 [a64] Fix ResolveFunction thunk
Register was getting stomped over

2024-06-23 14:00:23 -07:00
Wunkolo e5fd3d340c [a64] Implement `OPCODE_PACK`(SHORT)
Fails unit tests due to subtle rounding errors

`SHORT_4` unit-test is missing but implementation is the same as `SHORT_4`
2024-06-23 14:00:23 -07:00
Wunkolo 3b2612bfc0 [a64] Implement `OPCODE_PACK`(FLOAT16)
Fails the unit tests due to subtle rounding errors
2024-06-23 14:00:23 -07:00
Wunkolo e62f3f31d4 [a64] Fix native vector calls
Arguments need to be pointers stored in X0, X1, X2, ... rather than bassed directly in Q0, Q1 etc.

There are no unit tests for these functions in particular.
2024-06-23 14:00:23 -07:00
Wunkolo 35e8a809b1 [a64] Implement `OPCODE_VECTOR_ADD`
There is quite literally an instruction for each and every one of these cases.

Passes unit tests
