| 24 | /* The difference between readelf and objdump: |
| 25 | |
| 26 | Both programs are capable of displaying the contents of ELF format files, |
| 27 | so why does the binutils project have two file dumpers ? |
| 28 | |
| 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. */ |
