9eb20dd8 | 26 | /* The difference between readelf and objdump: |
252b5132 | 27 | |
74013231 | 28 | Both programs are capable of displaying the contents of ELF format files, |
9eb20dd8 | 29 | so why does the binutils project have two file dumpers ? |
0de14b54 | 30 | |
9eb20dd8 NC |
31 | The reason is that objdump sees an ELF file through a BFD filter of the |
32 | world; if BFD has a bug where, say, it disagrees about a machine constant | |
33 | in e_flags, then the odds are good that it will remain internally | |
34 | consistent. The linker sees it the BFD way, objdump sees it the BFD way, | |
35 | GAS sees it the BFD way. There was need for a tool to go find out what | |
36 | the file actually says. | |
37 | ||
38 | This is why the readelf program does not link against the BFD library - it | |
39 | exists as an independent program to help verify the correct working of BFD. | |
40 | ||
41 | There is also the case that readelf can provide more information about an | |
42 | ELF file than is provided by objdump. In particular it can display DWARF | |
43 | debugging information which (at the moment) objdump cannot. */ | |
