1.1       root        1: short term:
                      2: ----------
                      3: - debug option in 'configure' script + disable -fomit-frame-pointer
                      4: - Precise VGA timings for old games/demos (malc patch)

                      7: - warning for OS/2: must not use 128 MB memory (merge bochs cmos patch ?)
                      8: - config file (at least for windows/Mac OS X)
                      9: - commit message if execution of code in IO memory
                     10: - update doc: PCI infos.
                     11: - VNC patch + Synaptic patch.
                     12: - basic VGA optimizations
                     13: - physical memory cache (reduce qemu-fast address space size to about 32 MB)
                     14: - better code fetch (different exception handling + CS.limit support)
                     15: - do not resize vga if invalid size.
                     16: - avoid looping if only exceptions
                     17: - cycle counter for all archs
                     18: - TLB code protection support for PPC
                     19: - see openMosix Doc 
                     20: - disable SMC handling for ARM/SPARC/PPC (not finished)
                     21: - see undefined flags for BTx insn
                     22: - user/kernel PUSHL/POPL in helper.c
                     23: - keyboard output buffer filling timing emulation
                     24: - return UD exception if LOCK prefix incorrectly used
                     25: - test ldt limit < 7 ?
                     26: - tests for each target CPU
                     27: - fix CCOP optimisation
                     28: - fix all remaining thread lock issues (must put TBs in a specific invalid
                     29:   state, find a solution for tb_flush()).
                     30: - fix arm fpu rounding (at least for float->integer conversions)
                     31: - SMP support
                     32: 
                     33: ppc specific:
                     34: ------------
                     35: - TLB invalidate not needed if msr_pr changes
                     36: - SPR_ENCODE() not useful
                     37: - enable shift optimizations ?
                     38: 
                     39: lower priority:
                     40: --------------
                     41: - more friendly BIOS (logo)
                     42: - int15 ah=86: use better timing
                     43: - suppress shift_mem ops
                     44: - fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret)
                     45: - optimize FPU operations (evaluate x87 stack pointer statically)
                     46: - add IPC syscalls
                     47: - use -msoft-float on ARM
                     48: - use kernel traps for unaligned accesses on ARM ?
                     49: - handle rare page fault cases (in particular if page fault in helpers or
                     50:   in syscall emulation code).
                     51: - fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID)
                     52: - more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit
                     53:   issues, fix 16 bit uid issues)
                     54: - use page_unprotect_range in every suitable syscall to handle all
                     55:   cases of self modifying code.
                     56: - use gcc as a backend to generate better code (easy to do by using
                     57:   op-i386.c operations as local inline functions).
