-- optimize translated cache chaining (DLL PLT-like system)
+short term:
+----------
+- XP install bug fix
+- handle Self Modifying Code even if modifying current TB (BE OS 5 install)
+- L4 Pistachio kernel boot fix
+- TLB code protection support for PPC
+- add sysenter/sysexit and fxsr for L4 pistachio 686
+- basic VGA optimizations
+- disable SMC handling for ARM/SPARC/PPC
+- see undefined flags for BTx insn
+- user/kernel PUSHL/POPL in helper.c
+- keyboard output buffer filling timing emulation
+- verify tb_flush() with a20 and TLBs
+- return UD exception if LOCK prefix incorrectly used
+- cmos clock update and timers
+- test ldt limit < 7 ?
+- tests for each target CPU
+- fix CCOP optimisation
+- fix all remaining thread lock issues (must put TBs in a specific invalid
+ state, find a solution for tb_flush()).
+- fix arm fpu rounding (at least for float->integer conversions)
+- SMP support
+
+lower priority:
+--------------
+- suppress shift_mem ops
+- fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret)
+- sysenter/sysexit emulation
+- optimize FPU operations (evaluate x87 stack pointer statically) and
+ fix cr0.TS emulation
+- add IPC syscalls
+- 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)
-- finish signal handing (fp87 state, more siginfo conversions)
-- verify thread support (clone() and various locks)
-- vm86 syscall support
-- overrides/16bit for string ops
-- 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)
+- 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
