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:
|

|
|
|
|
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). */

``struct gdbarch'' for this architecture.

The INFO parameter is, as far as possible, be pre-initialized with

information obtained from INFO.ABFD or the global defaults.

of all the previously created architures for this architecture

|
values from the previously selected architecture for this

architecture family.

architecture is just a synonym for an earlier architecture (see
