[PATCH] D133376: Allow epilogue_begin to be emitted when generating DWARF

[John Reagan via Phabricator via llvm-commits]

JohnReagan added a comment.

Thanks for this.  On OpenVMS, our calling convention wants to know about both prologue and epilogue sections.  For asych-error handling, we won't call a routine's handler (ie, personality-routine) if it is in its prologue or epilogue since the routine's frame is no longer active.  In those cases, we walk back up the stack one frame to begin our handler search.  Today, we just look at the instruction sequences and trying to guess as best we can.  Having something in the debug_line table will be a big help.
