+ /* There is way too much undoing of half-known state here. The caller,
+ bfd_check_format_matches, really shouldn't iterate on live bfd's to
+ check match/no-match like it does. We have to rely on that a call to
+ bfd_default_set_arch_mach with the previously known mach, undoes what
+ was done by the first bfd_default_set_arch_mach (with mach 0) here.
+ For this to work, only elf-data and the mach may be changed by the
+ target-specific elf_backend_object_p function. Note that saving the
+ whole bfd here and restoring it would be even worse; the first thing
+ you notice is that the cached bfd file position gets out of sync. */
