Log Message:
m68k/fpe: Fix several FMOVEM FPctl emulation.
- Fix the write order of FMOVEM FPctl,-(An).
For example, "FMOVEM FPCR/FPSR,-(An)" instruction first decrements An by
the total size (4*2 bytes), then writes FPCR and FPSR in this order.
Therefore, it's differs from "FMOVEM FPCR,-(An); FMOVEM FPSR,-(An)" sequence.
- Support multiple immediate case like "FMOVEM #imm/#imm,FPCR/FPIAR".
- Mask writes to FPSR and FPCR registers correctly.
- Support reglist=0 case too. It's not common case but makes code easier.
