++  libdwarf now reads .debug_gnu_pubtypes & pubnames
++  (non-standard but gcc creates them in DWARF5)
++  via a small number of new functions
++  and dwarfdump  --print-debug-gnu prints both sections.
++  Verifying the .debug_info offsets is not yet done.
++2020-06-29:
++  Dwarfdump now dumps DWARF5 .debug_rnglists and
++  .debug_loclists.  To handle DWARF5 there are
++  a small number of new functions. All existing
++  functions are still supported, but
++  to read DWARF5 some small changes are required.
++  In libdwarf see libdwarf2.1.pdf and also see
++  libdwarf/ChangeLog for details. 
++2020-05-23:
++  dwarfdump now takes much less malloc() to work, as measured
++  by valgrind --tool=massif  and massif-visualizer.
++  A dwarfdump run that did 2.2Gib of malloc/free before the changes
++  now does 1.4GiB.
++2020-05-19:
++  libdwarf and dwarfdump now support DWARF5 .debug_rnglists.
++  The new interfaces are documented in libdwarf/libdwarf2.1.pdf.
++  The new option to dwarfdump is "--print-raw-rnglists".
