Subject: 	* dwarf2loc.h (struct dwarf2_locexpr_baton) <data>: Now const.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=947bb88ff5da0770e9d6a238b54b7053ba8bd6fb;p=binutils-gdb.git

	* dwarf2loc.h (struct dwarf2_locexpr_baton) <data>: Now const.
	(struct dwarf2_loclist_baton) <data>: Likewise.
	* dwarf2loc.c (find_location_expression): Constify return type.
	(dwarf2_evaluate_loc_desc): Make 'data' argument const.
	(dwarf2_loc_desc_needs_frame): Likewise.
	(loclist_read_variable): Constify.
	(loclist_describe_location): Likewise.
	(loclist_tracepoint_var_ref): Likewise.
