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