            Bug ID: 36987
           Summary: Add support for optimization remarks at MC level
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: MC
          Assignee: unassignedbugs at nondot.org

There is currently no way to emit optimisation remark at the MC level.

It would be nice to have this, at least per function with the source location
being the function definition.

One use case I want from this is emitting remarks for compact unwinding:
"compact unwinding cannot represent this function, falling back on DWARF".
