ibute StackMap u2 attribute_name_index; u4 attribute_length uoffset number_of_entries; stack_map_frame entries[number_of_entries]; } Each stack map frame has the following format:
stack_map_frame { uoffset offset; ulocalvar number_of_locals; verification_type_info locals[number_of_locals]; ustack number_of_stack_items; verification_type_info stack[number_of_stack_items]; } The
verification_type_info structure consists of a one-byte tag followed by zero or more bytes, giving more information about the tag. Each
verification_type_info structure specifies the verification type of one or two locations.
