Subject: [PATCH v2 35/42] Pass dwarf2_per_bfd instead of dwarf2_per_objfile to some index-related functions
Date: Tue, 12 May 2020 17:17:05 -0400 [thread overview]
Message-ID: <20200512211712.6543-36-simon.marchi@efficios.com> (raw)
In-Reply-To: <20200512210913.5593-1-simon.marchi@efficios.com>
From: Simon Marchi <simon.marchi@polymtl.ca>
All these functions actually only need to receive a dwarf2_per_bfd, pass
that instead of dwarf2_per_objfile.
gdb/ChangeLog:
* dwarf2/read.c (create_cu_from_index_list): Replace
dwarf2_per_objfile parameter with dwarf2_per_bfd.
(create_cus_from_index_list): Likewise.
(create_cus_from_index): Likewise.
(create_signatured_type_table_from_index): Likewise.
(create_cus_from_debug_names_list): Likewise.
(create_cus_from_debug_names): Likewise.
(dwarf2_read_gdb_index): Update.
(dwarf2_read_debug_names): Update.
