| /* 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. */ |
