Just a couple of remarks: - the epilogue isn't fully RTL-ized, - delay slot filling for epilogue doesn't work: DELAY_SLOTS_FOR_EPILOGUE isn't defined anymore so defining ELIGIBLE_FOR_EPILOGUE_DELAY is useless. I'm going to fix these minor issues, as well as try to refactor the code a bit. One question: I presume there is no point in supporting -mflat in 64-bit mode for the time being? -- Eric Botcazou
