1 | Correctness issues: |
| 2 | ||
| bd7a7b33 | 3 | - some eflags manipulation incorrectly reset the bit 0x2. |
| 872929aa | 4 | - SVM: test, cpu save/restore, SMM save/restore. |
| 044ef8ea | 5 | - x86_64: lcall/ljmp intel/amd differences ? |
| 044ef8ea FB |
6 | - better code fetch (different exception handling + CS.limit support) |
| 7 | - user/kernel PUSHL/POPL in helper.c | |
| 8 | - add missing cpuid tests | |
| 9 | - return UD exception if LOCK prefix incorrectly used | |
| 10 | - test ldt limit < 7 ? | |
| 11 | - fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret) | |
| 12 | - full support of segment limit/rights | |
| 13 | - full x87 exception support | |
| 14 | - improve x87 bit exactness (use bochs code ?) | |
| b8b6a50b FB |
15 | - DRx register support |
| 16 | - CR0.AC emulation | |
| 17 | - SSE alignment checks | |

| 19 | Optimizations/Features: | |
| 20 | ||
| b8b6a50b FB |
21 | - add SVM nested paging support |
| 22 | - add VMX support | |
| 23 | - add AVX support | |
| 24 | - add SSE5 support | |
| 12e26b75 FB |
25 | - fxsave/fxrstor AMD extensions |
| 26 | - improve monitor/mwait support | |
| 3bd7da9e FB |
27 | - faster EFLAGS update: consider SZAP, C, O can be updated separately |
| 28 | with a bit field in CC_OP and more state variables. | |
| 044ef8ea FB |
29 | - evaluate x87 stack pointer statically |
| 30 | - find a way to avoid translating several time the same TB if CR0.TS | |
| 31 | is set or not. |
