| TODO-list: |
| |
| CPU common: |
| - Unimplemented features/bugs: |
| - Delay slot handling may fail sometimes (branch end of page, delay |
| slot next page) |
| - Atomical instructions |
| - CPU features should match real CPUs (also ASI selection) |
| - Optimizations/improvements: |
| - Condition code/branch handling like x86, also for FPU? |
| - Remove remaining explicit alignment checks |
| - Global register for regwptr, so that windowed registers can be |
| accessed directly |
| - Improve Sparc32plus addressing |
| - NPC/PC static optimisations (use JUMP_TB when possible)? (Is this |
| obsolete?) |
| - Synthetic instructions |
| - MMU model dependant on CPU model |
| - Select ASI helper at translation time (on V9 only if known) |
| - KQemu/KVM support for VM only |
| - Hardware breakpoint/watchpoint support |
| - Cache emulation mode |
| - Reverse-endian pages |
| - Faster FPU emulation |
| - Busy loop detection |
| |
