  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
  23 + - Reverse-endian pages
  24 + - Faster FPU emulation
  25 + - Busy loop detection
