+- 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)
- add IPC syscalls

 lower priority:
 --------------
- sysenter/sysexit emulation
+- add IPC syscalls
 - SMP support
- finish segment ops (call far, ret far, load_seg suppressed)
 - 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

+/*
+   SPARC has two pitfalls: Delay slots and (a)nullification.
+   This is currently solved as follows:
+
+   'call' instructions simply execute the delay slot before the actual
+   control transfer instructions.
+
+   'jmpl' instructions execute calculate the destination, then execute
+   the delay slot and then do the control transfer.
+
+   (conditional) branch instructions are the most difficult ones, as the
+   delay slot may be nullified (ie. not executed). This happens when a
+   conditional branch is not executed (thus no control transfer happens)
+   and the 'anull' bit in the branch instruction opcode is set. This is
+   currently solved by doing a jump after the delay slot instruction.
+
+   There is also one big (currently unsolved) bug in the branch code:
+   If a delay slot modifies the condition codes then the new condition
+   codes, instead of the old ones will be used.
+
+   TODO-list:
+
+   FPU-Instructions
+   Coprocessor-Instructions
+   Fix above bug
+   Check signedness issues
+   Privileged instructions
+   Register window overflow/underflow check
+   Optimize synthetic instructions
+   Optional alignment and privileged instruction check
