--- Comment #8 from Jeffrey A. Law <law at redhat dot com> ---
That code was part of the fix for pr41883 and I doubt the change is right
as-is.
The questions I'd have:
1. The code clearly assumes that after the EPILOGUE_BEG we have a real insn.
Why is that assumption not true here.
2. Assuming the reason for #1 is valid, where should the REG_SAVE_NOTE be
placed to keep the dwarf2 emitter happy. Blindly going to the next real insn
may not be correct. Consider if the EPILOGUE_BEG note is the same as TAIL. In
the case where we "just" cross into another block, is placing the note on an
insn in another block correct?
