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 dependent 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
