- tests for each target CPU

- ppc qemu test

- optimize FPU operations (evaluate x87 stack pointer statically) and

  fix cr0.TS emulation

- fix some 16 bit sp push/pop overflow

- sysenter/sysexit emulation

- finish segment ops (call far, ret far, load_seg suppressed)

- fix CCOP optimisation

- fix all remaining thread lock issues (must put TBs in a specific invalid

  state, find a solution for tb_flush()).

- cpu loop optimisation (optimise ret case as the cpu state does not change)

- fix arm fpu rounding (at least for float->integer conversions)

lower priority:

--------------

- add IPC syscalls

- SMP support

- use -msoft-float on ARM

- use kernel traps for unaligned accesses on ARM ?

- handle rare page fault cases (in particular if page fault in heplers or

  in syscall emulation code).

- fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID)

- more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit

  issues, fix 16 bit uid issues)

- use page_unprotect_range in every suitable syscall to handle all

  cases of self modifying code.

- use gcc as a backend to generate better code (easy to do by using

  op-i386.c operations as local inline functions).

- add SSE2/MMX operations
