Subject: [PATCH v2 07/42] Move die_type_hash to dwarf2_per_objfile
Date: Tue, 12 May 2020 17:08:38 -0400 [thread overview]
Message-ID: <20200512210913.5593-8-simon.marchi@efficios.com> (raw)
In-Reply-To: <20200512210913.5593-1-simon.marchi@efficios.com>
The die_type_hash field can't be shared between multiple obfiles, as it
holds `struct type` objects, which are objfile-specific. Move it from
dwarf2_per_bfd to dwarf2_per_objfile and update all references.
gdb/ChangeLog:
* dwarf2/read.h (struct dwarf2_per_bfd) <die_type_hash>: Move to
struct dwarf2_per_objfile.
(struct dwarf2_per_objfile) <die_type_hash>: Move from struct
dwarf2_per_bfd.
* dwarf2/read.c (set_die_type): Update.
(get_die_type_at_offset): Update.
