I considered to use it as a starting point to build the control-flow graph of
a function in order to display it in a custom profiler we use internally since
I could assume that I had the debugging information and I had to read the
.debug_line section anyway to get the source lines.
I ended up not using it and it's clear to me that its practical uses may be
questionable ("fast" single stepping in a debugger?) but I thought it might
be worth to share it.
