/* 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. */
