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

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

Passes unit tests
 2024-06-23 14:00:23 -07:00

Wunkolo 88ed113541 [a64] Remove volatile storing of X0/Q0 
We dont load it back so no need to store it
 2024-06-23 14:00:22 -07:00
Wunkolo 07a4df8e2f [a64] Implement OPCODE_VECTOR_SHL 
Vector registers are passed as pointers rather than directly in the `Qn` registers. So these functions should be taking pointer-type arguments rather than vector-register types directly.

Fixes `OPCODE_VECTOR_SHL` and passes unit tests.
 2024-06-23 14:00:22 -07:00
Wunkolo 3d345d71a7 [a64] Fix overwriting of return-value registers 
These are stomping over X0 and Q0 which is returning input argument registers as return values.
Fixes some guest-to-host calls.
 2024-06-23 14:00:22 -07:00
Wunkolo 6a0e6a9ca9 [a64] Fix indirect and external calls 2024-06-23 14:00:22 -07:00

Wunkolo 124f684987 [a64] Fix Guest-To-Host native calls 
These calls need to preserve and restore the `lr` register.

Unit tests all run now!
 2024-06-23 14:00:22 -07:00
