Wunkolo e2d1e5d7f8 [a64] Optimize vector-constant generation 
Uses MOVI to optimize some cases of constants rather than EOR.
MOVI is a register-renaming idiom on many architectures.

Wunkolo a7ae117c90 [a64] Implement b bl br blr cbnz cbz instruction-stepping 2024-06-23 14:00:26 -07:00
Wunkolo c3efaaa286 [a64] Implement instruction stepping. 
Uses `0x0000'dead` as an instructon-stepping sentinel value.
Support for basic jumping instructions like `b`, `bl`, `br`, and `blr`.

Wunkolo eb0736eb25 [a64] Reduce function prolog/epilog to 16 bytes 
Just need to store `fp` and `lr`
 2024-06-23 14:00:26 -07:00
Wunkolo a54226578e [a64] Implement memory tracing 2024-06-23 14:00:26 -07:00
Wunkolo f1235be462 [a64] Fix ATOMIC_COMPARE_EXCHANGE_I32 comparison type 
This fixes 32-bit atomic-compare-exchanges.
The upper-half of the input register _must_ be clipped off.

This fixes a deadlock in some games.
 2024-06-23 14:00:25 -07:00
Wunkolo c33f543503 [a64] Implement kDebugInfoTraceFunctions and kDebugInfoTraceFunctionCoverage 
Relies on armv8.1-a atomic features
 2024-06-23 14:00:25 -07:00
Wunkolo bec248c2f8 [a64] Fix OPCODE_CNTLZ 
8 and 16 bit CNTLZ needs its bit-count fixed to its original element-type
 2024-06-23 14:00:25 -07:00
Wunkolo b9d0752b40 [a64] Optimize OPCODE_MUL_ADD 
Use `FMADD` and `FMLA`
Tests are the same, though now it should run a bit faster.
The tests that fail are primarily denormals and other subtle precision
issues it seems.

Ex:
```
i> 00002358   - vmaddfp_7298_GEN
!> 00002358 Register v4 assert failed:
!> 00002358   Expected: v4 == [00000000, 00000000, 00000000, 00000000]
!> 00002358     Actual: v4 == [000D000E, 00138014, 000E4CDC, 0018B34D]
!> 00002358     TEST FAILED
```

Host-To-Guest and Guest-To-Host thunks should probably restore/preserve
the FPCR to maintain these roundings.

Wunkolo 684904c487 [a64] Implement PERMUTE_V128(int16) 
Passes 'vmrghh' and `vmrglh` unit-tests
 2024-06-23 14:00:25 -07:00
Wunkolo 7eca228027 [a64] Fix VECTOR_CONVERT_F2I rounding 
```
4.2.2.4 Floating-Point Rounding and Conversion Instructions
...
Floating-point conversions to integers (vctuxs, vctsxs) use round-toward-zero (truncate).
...
```

This passes all of the `vctuxs` and `vctsxs` unit tests
