* dwarf2-frame.c (no_dwarf_call): New function.
(execute_stack_op): Set CTX->DWARF_CALL.
* dwarf2expr.c (execute_stack_op) <DW_OP_call2, DW_OP_call4>: New.
* dwarf2expr.h (struct dwarf_expr_context) <dwarf_call>: New.
(struct dwarf_expr_context) <get_subr>: Remove the #if0-ed field.
* dwarf2loc.c (per_cu_dwarf_call, dwarf_expr_dwarf_call): New functions.
(dwarf2_evaluate_loc_desc): Initialize CTX->DWARF_CALL.
