[llvm-dev] [DWARF] Why epilogue_begin was not emitted?

[Tetsuya Ooka via llvm-dev]

Hello,

I found that prologue_end flag is emitted in dwarf debug information by the most of llvm backend but epilogue_begin flag is never.
Please tell me why the specification is like this. I think this is asymmetry.
And I would also like to know how lldb find the end of function body without epilogue_begin flag.

Thank you,
Tetsuya Ooka
