    sys/ddb              db_elf.c 
  Log:
  Reworked rev.1.14.  Use the ELF symbol type again to summarily reject
  some symbols in X_db_search_symbol().  Reject the same symbols that
  rev.1.13 did (all except STT_OBJECT and STT_FUNC), except don't reject
  typeless symbols.  This keeps the typeless symbols in non-verbosely
  written assembler code visible, but makes file symbols invisible.  ELF
  file symbols have type STT_FILE and value 0, so this stops small values
  and offsets sometimes being displayed in terms of the first file symbol
  in the kernel (usually device_if.c).  I think it rejects some other
  unwanted symbols (small absolute symbols for things like struct offsets).
  It may reject some wanted symbols (large absolute symbols for addresses
  like PTmap).
