1069 A "special case" is considered to be an unknown token, i.e., a token
1070 that the parser does not know how to parse. A good example of special
1071 case would be ARM's register displacement syntax:

1075 Since the parser assumes that a register displacement is of the form:
1077 <number> <indirection_prefix> <register_name> <indirection_suffix>
1079 it means that it will not be able to recognize and parse this odd syntax.
1080 Therefore, we should add a special case function that will handle this token.

1083 using GDB's internal expression mechanism (e.g., `write_exp_elt_opcode'
