Subject: [PATCH 12/14] Fix a memory leak and remove an unused member
Date: Sat, 15 Feb 2020 16:55:00 -0000 [thread overview]
Message-ID: <20200215165444.32653-13-tom@tromey.com> (raw)
In-Reply-To: <20200215165444.32653-1-tom@tromey.com>
I noticed that setup_type_unit_groups leaks the symtab vector -- it
allocates this with XNEWVEC, but from what I can tell, nothing frees
it. This patch changes it to use XOBNEWVEC.
Also, the type_unit_unshareable::num_symtabs member is assigned but
never read. So, this removes it.
2020-02-15 Tom Tromey <tom@tromey.com>
* dwarf2/read.h (struct type_unit_unshareable) <num_symtabs>:
Remove.
* dwarf2/read.c (dwarf2_cu::setup_type_unit_groups): Use
XOBNEWVEC.
