| 1 | +TODO-list: | |
| 2 | + | |
| 3 | +CPU common: | |
| 4 | +- Unimplemented features/bugs: | |
| 5 | + - Delay slot handling may fail sometimes (branch end of page, delay | |
| 6 | + slot next page) | |
| 7 | + - Atomical instructions | |
| 8 | + - CPU features should match real CPUs (also ASI selection) | |
| 9 | +- Optimizations/improvements: | |
| 10 | + - Condition code/branch handling like x86, also for FPU? | |
| 11 | + - Remove explicit alignment checks | |
| 12 | + - Global register for regwptr, so that windowed registers can be | |
| 13 | + accessed directly | |
| 14 | + - Improve Sparc32plus addressing | |
| 15 | + - NPC/PC static optimisations (use JUMP_TB when possible)? (Is this | |
| 16 | + obsolete?) | |
| 17 | + - Synthetic instructions | |
| 18 | + - MMU model dependant on CPU model | |
| 19 | + - Select ASI helper at translation time (on V9 only if known) | |
| 20 | + - KQemu/KVM support for VM only | |
| 21 | + - Hardware breakpoint/watchpoint support | |
| 22 | + - Cache emulation mode | |
