The linker sees it the BFD way, objdump sees it the BFD way, 34 GAS sees it the BFD way. There was need for a tool to go find out what 35 the file actually says. 36 37 This is why the readelf program does not link against the BFD library - it 38 exists as an independent program to help verify the correct working of BFD. 39 40 There is also the case that readelf can provide more information about an 41 ELF file than is provided by objdump. In particular it can display DWARF 42 debugging information which (at the moment) objdump cannot. */ 43 44 #include "sysdep.h" 46 #include <assert.h> 47 #include <time.h> 48 #ifdef HAVE_ZLIB_H 49 #include <zlib.h> 50 #endif 51 #ifdef HAVE_WCHAR_H 52 #include <wchar.h> 53 #endif 54 55 #if __GNUC__ >= 2 56 /* Define BFD64 here, even if our default architecture is 32 bit ELF 57 as this will allow us to read in and parse 64bit and 32bit ELF files. 58 Only do this if we believe that the compiler can support a 64 bit 59 data type.
