Subject: [PATCH v2 30/42] Add dwarf2_per_objfile parameter to get_die_type_at_offset
Date: Tue, 12 May 2020 17:17:00 -0400	[thread overview]
Message-ID: <20200512211712.6543-31-simon.marchi@efficios.com> (raw)
In-Reply-To: <20200512210913.5593-1-simon.marchi@efficios.com>

From: Simon Marchi <simon.marchi@polymtl.ca>

This allows removing some dwarf2_per_cu_data::dwarf2_per_objfile
references.

gdb/ChangeLog:

	* dwarf2/read.h (dwarf2_get_die_type): Add dwarf2_per_objfile
	parameter.
	* dwarf2/read.c (get_die_type_at_offset): Likewise.
	(read_namespace_alias): Update.
	(lookup_die_type): Update.
	(dwarf2_get_die_type): Add dwarf2_per_objfile parameter.
	* dwarf2/loc.c (class dwarf_evaluate_loc_desc) <get_base_type>:
	Update.
	(disassemble_dwarf_expression): Update.
