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)


Handle null DIE in dump_die:
(gdb) call dump_die (0)
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)

Committed to trunk.
