Subject: [committed] Handle null DIE in dump_die
Date: Tue, 01 Jan 2019 00:00:00 -0000	[thread overview]
Message-ID: <20191203195536.GA24458@delia> (raw)

Hi,

Handle null DIE in dump_die:
...
(gdb) call dump_die (0)
 null
...
allowing us to do something like:
...
(gdb) call dump_die (child->die_nextdup)
 5a O 3737fe8a e3113fb8 bla class_type
(gdb) call dump_die (child->die_nextdup->die_nextdup)
 ef O 3737fe8a e3113fb8 bla class_type
(gdb) call dump_die (child->die_nextdup->die_nextdup->die_nextdup)
 null
...

Committed to trunk.

Thanks,
- Tom
