Move get_object_address to dwarf_expr_context
Following the idea of merging the evaluators, the get_object_address
and can be moved from dwarf_expr_executor and dwarf_evaluate_loc_desc
classes to their base class dwarf_expr_context.
gdb/ChangeLog:
* dwarf2/expr.c (dwarf_expr_context::get_object_address): Move
from dwarf_evaluate_loc_desc.
(class dwarf_expr_context): Add object address member to
dwarf_expr_context.
* dwarf2/expr.h (dwarf_expr_context::get_frame_pc): Remove
method.
* dwarf2/frame.c (dwarf_expr_executor::get_object_address):
Remove method.
* dwarf2/loc.c (dwarf_evaluate_loc_desc::get_object_address):
move to dwarf_expr_context.
(class dwarf_evaluate_loc_desc): Move object address member to
dwarf_expr_context.
