[RFC] Looking to fix AIX whatis-ptype-typedefs.exp

Respected community members,

Hi,

In AIX we currently pass 28362 test cases and fail 2166 test cases while running gdb.base testsuite.

Of all the failures we are fixing one by one Whatis-ptype-typedefs.exp test case has 1062 failures.

The issue:-

When we try to check a type which is type casted then we are getting a syntax error. This looks like a parsing issue at first glance.

For example,
(gdb) whatis (void_typedef) void_typedef
A syntax error in expression, near `'.

Or

(gdb) whatis (func_ftype) int_typedef
A syntax error in expression, near `'.
(gdb) ptype (func_ftype) int_typedef
A syntax error in expression, near `'.

Whenever we typecast, we get this error message.

I am trying to understand why this happened while in other targets it runs smoothly.  To fix the same for GDB community and AIX I need some guidance. Kindly help me with your knowledge and expertise.

Do we need to install any parsing package and need to configure GDB to use the same? Or is it got to with incorrect AIX specific code which is parsing the command. If it is the latter, then let me know the starting point to understand why this happened.

Hoping for a reply,

Have a nice day ahead.

Thanks and regards,
Aditya.
