ld by default (and always, unless adjusted with a hand-rolled linker script) emits deduplicated CTF into the .ctf section. But viewing it needs you to explicitly tell objdump this: it doesn't default its argument, even though what you always end up typing is --ctf=.ctf. This is annoying, so make the argument optional. binutils/ChangeLog 2021-10-25 Nick Alcock <nick.alcock@oracle.com> * objdump.c (usage): --ctf now has an optional argument. (main): Adjust accordingly. (dump_ctf): Default it. * doc/ctf.options.texi: Adjust. ld/ChangeLog 2021-10-25 Nick Alcock <nick.alcock@oracle.com> * testsuite/ld-ctf/array.d: Change --ctf=.ctf to --ctf. * testsuite/ld-ctf/conflicting-cycle-1.B-1.d: Likewise. * testsuite/ld-ctf/conflicting-cycle-1.B-2.d: Likewise. * testsuite/ld-ctf/conflicting-cycle-1.parent.d: Likewise. * testsuite/ld-ctf/conflicting-cycle-2.A-1.d: Likewise. * testsuite/ld-ctf/conflicting-cycle-2.A-2.d: Likewise. * testsuite/ld-ctf/conflicting-cycle-2.parent.d: Likewise. * testsuite/ld-ctf/conflicting-cycle-3.C-1.d: Likewise. * testsuite/ld-ctf/conflicting-cycle-3.C-2.d: Likewise. * testsuite/ld-ctf/conflicting-cycle-3.parent.d: Likewise. * testsuite/ld-ctf/conflicting-enums.d: Likewise. * testsuite/ld-ctf/conflicting-typedefs.d: Likewise. * testsuite/ld-ctf/cross-tu-cyclic-conflicting.d: Likewise. * testsuite/ld-ctf/cross-tu-cyclic-nonconflicting.d: Likewise. * testsuite/ld-ctf/cross-tu-into-cycle.d: Likewise. * testsuite/ld-ctf/cross-tu-noncyclic.d: Likewise. * testsuite/ld-ctf/cycle-1.d: Likewise. * testsuite/ld-ctf/cycle-2.A.d: Likewise. * testsuite/ld-ctf/cycle-2.B.d: Likewise. * testsuite/ld-ctf/cycle-2.C.d: Likewise. * testsuite/ld-ctf/data-func-conflicted.d: Likewise. * testsuite/ld-ctf/diag-cttname-null.d: Likewise. * testsuite/ld-ctf/diag-cuname.d: Likewise. * testsuite/ld-ctf/diag-parlabel.d: Likewise. * testsuite/ld-ctf/enum-forward.d: Likewise. * testsuite/ld-ctf/enums.d: Likewise. * testsuite/ld-ctf/forward.d: Likewise. * testsuite/ld-ctf/function.d: Likewise. * testsuite/ld-ctf/nonrepresentable.d: Likewise. * testsuite/ld-ctf/slice.d: Likewise. * testsuite/ld-ctf/super-sub-cycles.d: Likewise.

@c This file contains the entry for the --ctf, --ctf-parent, --ctf-symbols, -and

@c --ctf-strings options that are common to both readelf and objdump.

Display the contents of the specified CTF section. CTF sections themselves
|
|
contain many subsections, all of which are displayed in order.
|
|
|
|
By default, display the name of the section named @var{.ctf}, which is the
|
|
name emitted by @command{ld}.
|
|
|
|
@item --ctf-parent=@var{member}
|
|
|
|
If the CTF section contains ambiguously-defined types, it will consist
|
|
of an archive of many CTF dictionaries, all inheriting from one
|
|
dictionary containing unambiguous types. This member is by default
|
|
named @var{.ctf}, like the section containing it, but it is possible to
|
|
change this name using the @code{ctf_link_set_memb_name_changer}
|
|
function at link time. When looking at CTF archives that have been
|
|
created by a linker that uses the name changer to rename the parent
|
|
archive member, @option{--ctf-parent} can be used to specify the name
|
|
used for the parent.
