Subject: [PATCH v4 10/34] Refactor build_type_psymtabs_reader
Date: Mon, 4 Apr 2022 13:53:11 -0600 [thread overview]
Message-ID: <20220404195335.2111906-11-tom@tromey.com> (raw)
In-Reply-To: <20220404195335.2111906-1-tom@tromey.com>
The new DWARF scanner needs to save the entire cutu_reader object, not
just parts of it. In order to make this possible, this patch
refactors build_type_psymtabs_reader. This change is done separately
because it is easy to review in isolation and it helps make the later
patches smaller.
