+# A "special case" is considered to be an unknown token, i.e., a token
+# 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).

+# In very specific situations, it may be necessary for the register
+# name present in a SystemTap probe's argument to be handled in a
+# special way. For example, on i386, GCC may over-optimize the
+# register allocation and use smaller registers than necessary. In
+# such cases, the client that is reading and evaluating the SystemTap
+# probe (ourselves) will need to actually fetch values from the wider
+# version of the register in question.
+#
+# To illustrate the example, consider the following probe argument
+# (i386):
+#
+# 4@%ax
+#
+# This argument says that its value can be found at the %ax register,
+# which is a 16-bit register. However, the argument's prefix says
+# that its type is "uint32_t", which is 32-bit in size. Therefore, in
+# this case, GDB should actually fetch the probe's value from register
+# %eax, not %ax. In this scenario, this function would actually
+# replace the register name from %ax to %eax.
