26 /* The difference between readelf and objdump:
28 Both programs are capable of displaying the contents of ELF format files,
29 so why does the binutils project have two file dumpers ?
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.
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.
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. */
55 /* Define BFD64 here, even if our default architecture is 32 bit ELF
56 as this will allow us to read in and parse 64bit and 32bit ELF files.
57 Only do this if we believe that the compiler can support a 64 bit
58 data type. For now we only rely on GCC being able to do this. */

9209 DWARF debug sections. This is a target specific test. Note - we do not
9210 go through the whole including-target-headers-multiple-times route, (as
9211 we have already done with <elf/h8.h>) because this would become very
9212 messy and even then this function would have to contain target specific
9213 information (the names of the relocs instead of their numeric values).
9214 FIXME: This is not the correct way to solve this problem. The proper way
9215 is to have target specific reloc sizing and typing functions created by
9216 the reloc-macros.h header, in the same way that it already creates the
9217 reloc naming functions. */
