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. */ | |
