Dwarf_Unsigned
dwarf_add_expr_gen(Dwarf_P_Expr expr, Dwarf_Small opcode, Dwarf_Unsigned val1, Dwarf_Unsigned val2, Dwarf_Error *err);
Argument expr should reference a location expression descriptor allocated using the function dwarf_new_expr(3).
Argument opcode specifies the operation code of the location expression operator. Valid values for this argument are those denoted by the DW_OP_* constants defined in <libdwarf.h>.
To generate a DW_OP_addr operation, application code should instead use dwarf_add_expr_addr_b(3).
Argument val1 specifies the first operand of the location expression operator.
Argument val2 specifies the second operand of the location expression operator.
If argument err is not NULL, it will be used to store error information in case of an error.
