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