Given that it's used elsewhere, is there more to it than just:
int
dumper::init_core_dump ()
{
bfd_init ();
- core_bfd = bfd_openw (file_name, "elf32-i386");
+ core_bfd = bfd_openw (file_name, "elf64-x86");
if (core_bfd == NULL)
{
bfd_perror ("opening bfd");
goto failed;
}
if (!bfd_set_format (core_bfd, bfd_core))
{
bfd_perror ("setting bfd format");
goto failed;
}
- if (!bfd_set_arch_mach (core_bfd, bfd_arch_i386, 0))
+ if (!bfd_set_arch_mach (core_bfd, bfd_arch_i386, bfd_mach_x86_64))
{
bfd_perror ("setting bfd architecture");
goto failed;
}
return 1;
failed:
dumper_abort ();
return 0;
}
