6    
7    
8  MIPS bintrans:  Old MIPS bintrans:
         x)  call/return address cache?  
9    
10  dyntrans:          x)  call/return address cache?
         x)  memory write protection for ARM, but NOT for Alpha (because  
                 it has the IMB instruction... hm)  
11    
12          x)  call/return address cache          x)  Turn the MIPS cpu family stuff into dyntrans.
13    
         x)  instr_call sequence analysis support? (Useful for  
                 handtuning combinations.)  
14    
15          x)  opcode statistics support?  Dyntrans:
                 TODO: is instr_call statistics enough?  
16    
17          x)  support for archs that allow transparent unaligned load/stores          x)  Separate data and instruction translations?
18    
19          x)  SMP: detect when an instruction such as ll/sc or cas is used,          x)  Generalize the inline quick_pc_to_pointers?
             and "synchronize" approximately the number of executed instructions  
             (or cycles) across all CPUs.  
20    
21          x)  support for variable-length instructions (x86, m68k, ...)          x)  Call/return hints...
                 Perhaps:  don't increase the next_ic between every  
                 instruction, but let each instruction's handler do  
                 that for itself.  
                 Problem: what about instructions crossing a (virtual)  
                         page boundary? They cannot be translated once  
                         and for all :( and must be interpreted slowly!  
22    
23          x)  support for THUMB or MIPS16  (arm, mips)          x)  More 64-bit stuff.
24    
25          x)  support for Delay slots!  (mips, sparc, hppa)          x)  Lots of other stuff: see src/cpus/README_DYNTRANS
26    
         x)  Alpha: hahaha, zapnot and inserts/extracts don't  
             compile into very nice code :-|  fix this  
27    
28          x)  64-bit virtual memory translation tables (PPC, etc)  Userland emulation:
29    
30          x)  x86: convert to dyntrans. LOTS of stuff to consider.          x)  Lots of stuff.
31    
32            x)  Dynamic linking? Hm.
