Subject: * objdump.c (objdump_print_addr): If displaying file offsets, show
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3276085244458aabe070c7975b052af343d7f59c;p=binutils-gdb.git

* objdump.c (objdump_print_addr): If displaying file offsets, show
  the offset even if there are no symbols available.
  (dump_section): Display nothing if none of the section is going to
  be dumped.  Display the file offset, if requested, of the location
  from where the dump starts.
  * doc/binutils.texi (objdump): Mention that dumping via the -s
  switch is also affected by the -F option.
