+# that the parser does not know how to parse. A good example of special
+# case would be ARM's register displacement syntax:
+#
+# [R0, #4] ;; displacing R0 by 4
+#
+# Since the parser assumes that a register displacement is of the form:
+#
+# <number> <indirection_prefix> <register_name> <indirection_suffix>
+#
+# it means that it will not be able to recognize and parse this odd syntax.
+# Therefore, we should add a special case function that will handle this token.
+#
+# This function should generate the proper expression form of the expression
+# using GDB\'s internal expression mechanism (e.g., \`write_exp_elt_opcode\'
+# and so on). It should also return 1 if the parsing was successful, or zero
+# if the token was not recognized as a special token (in this case, returning
+# zero means that the special parser is deferring the parsing to the generic
+# parser), and should advance the buffer pointer (p->arg).
