9eb20dd8 | 24 | /* The difference between readelf and objdump: |
252b5132 | 25 | |
74013231 | 26 | Both programs are capable of displaying the contents of ELF format files, |
9eb20dd8 | 27 | so why does the binutils project have two file dumpers ? |
0de14b54 | 28 | |
9eb20dd8 NC |
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. */ | |
