This patch adds a new command "info exceptions" whose purpose is to
provide the list of exceptions currently defined in the inferior.
The usage is:
(gdb) info exceptions [REGEXP]
Without argument, the command lists all exceptions. Otherwise,
only those whose name match REGEXP are listed.
For instance:
(gdb) info exceptions
All defined Ada exceptions:
constraint_error: 0x613dc0
program_error: 0x613d40
storage_error: 0x613d00
tasking_error: 0x613cc0
global_exceptions.a_global_exception: 0x613a80
global_exceptions.a_private_exception: 0x613ac0
The name of the command, as well as its output is part of a legacy
I inherited long ago. It's output being parsed by frontends such as
GPS, I cannot easily change it. Same for the command name.
The implementation is mostly self-contained, and is written in a way
that should make it easy to implement the GDB/MI equivalent. The
careful reviewer will notice that the code added in ada-lang.h could
normally be made private inside ada-lang.c. But these will be used
by the GDB/MI implementation. Rather than making those private now,
only to move them later, I've made them public right away.
gdb/ChangeLog:
* ada-lang.h: #include "vec.h".
(struct ada_exc_info): New.
(ada_exc_info): New typedef.
(DEF_VEC_O(ada_exc_info)): New vector.
(ada_exceptions_list): Add declaration.
* ada-lang.c (ada_is_exception_sym)
(ada_is_non_standard_exception_sym, compare_ada_exception_info)
(sort_remove_dups_ada_exceptions_list)
(ada_exc_search_name_matches, ada_add_standard_exceptions)
(ada_add_exceptions_from_frame, ada_add_global_exceptions)
(ada_exceptions_list_1, ada_exceptions_list)
(info_exceptions_command): New function.
