           Summary: dwarf marker for function return instruction
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug

It would be desirable to have a DWARF marker of some sort emitted
for the point(s) of a function that correspond to the logical moment
of its return.  This would ideally be a point where all the nearby
variables are still in scope, so the last-gasp variable state may be
examined.

Ideally, tail call sites would also have this marker, and so would
inlined functions.  One can dream...
