9eb20dd8 24/* The difference between readelf and objdump:
252b5132 25
74013231 26 Both programs are capable of displaying the contents of ELF format files,
9eb20dd8 27 so why does the binutils project have two file dumpers ?
0de14b54 28
9eb20dd8
NC		 29 The reason is that objdump sees an ELF file through a BFD filter of the
30 world; if BFD has a bug where, say, it disagrees about a machine constant
31 in e_flags, then the odds are good that it will remain internally
32 consistent. The linker sees it the BFD way, objdump sees it the BFD way,
33 GAS sees it the BFD way. There was need for a tool to go find out what
34 the file actually says.
35
36 This is why the readelf program does not link against the BFD library - it
37 exists as an independent program to help verify the correct working of BFD.
38
39 There is also the case that readelf can provide more information about an
40 ELF file than is provided by objdump. In particular it can display DWARF
41 debugging information which (at the moment) objdump cannot. */

10513 undefined symbols. However, symbols defined by the linker in
10514 .dynbss for variables copied from a shared library in order to
10515 avoid text relocations are defined yet have verneed. We could
10516 use a heuristic to detect the special case, for example, check
10517 for verneed first on symbols defined in SHT_NOBITS sections, but
10518 it is simpler and more reliable to just look for both verdef and
10519 verneed. .dynbss might not be mapped to a SHT_NOBITS section. */
