-- asynchronous signal interrupt / clear synchronous signal handling
-- add eflags restore in emulator
-- finish signal handing (fp87 state)
-- verify thread support (clone() and various locks)
-- optimize translated cache chaining (DLL PLT-like system)
-- vm86 syscall support
-- overrides/16bit for string ops
-- more syscalls (in particular all 64 bit ones)
-- make it self runnable (use same trick as ld.so : include its own relocator and libc)
-- improved 16 bit support 
-- fix FPU exceptions (in particular: gen_op_fpush not before mem load)
+- 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
