[Ada/tasks] Optimize ATCB lookups

Type symbols that are used to decode the Ada task control block may be
duplicated in any unit that uses a tasking feature; an Ada lookup of
these symbols would collect all the duplicated instances and could
provoke the load of a huge amount of debug symbols in the process.

However, when decoding the task information, we are only interested in
one instance; and we have the full name of the symbol anyway. So use
a C lookup instead of an Ada lookup.

2010-11-05  Jerome Guitton  <guitton@adacore.com>

* ada-tasks.c (get_tcb_types_info): Use C lookups to get
ATCB symbols.

infinite recursion with ada_check_typedef

When trying to resolve an incomplete type, if there is no complete
version of that type available, GDB can go in an infinite loop.

This is because ada_check_typedef makes a recursive call to itself,
in an attempt to make sure that the returned type is never a typedef.
However, when no complete type is found, the current logic causes us
to keep going indefinitely through the same path...

This patch fixes the problem by performing the recursive call to
ada_check_typedef only when a TYPE_CODE_TYPDEF layer needs to be
stripped.

gdb/ChangeLog:

        * ada-lang.c (ada_check_typedef): Call ada_check_typedef only
        if type1 is a typedef.

Add `_finalizer' to the list of known GNAT auxilary routines.

This is a new routine that is being generated by the expander in
the context of controlled types.  This patch adds it to the list of such
routines so that the debugger does not show it when selecting the first
"user" frame (when switching tasks for instance).

gdb/ChangeLog:

        * ada-lang.h (ADA_KNOWN_AUXILIARY_FUNCTION_NAME_PATTERNS): Add
        "_finalizer" to the list.

Remove commented-out code in symfile.c

This patch removes some code that has been `#if 0'-ed since at least
1999 or 2000...

gdb/ChangeLog:

        * symfile.c: Remove all "#if 0"/"#endif" blocks.

symfile.c: Add missing second space after period.

gdb/ChangeLog:

        * symfile.c: Add missing second space after period in various comments.

Minor comment reformatting in ada-typeprint.c

gdb/ChangeLog:

        * ada-typeprint.c (print_array_type): Fix formatting in comment.
        (print_selected_record_field_types): Fix formatting in function
        documentation.

copy/paste typo when registering the `show ravenscar' prefix command

gdb/ChangeLog:

        * ravenscar-thread.c (_initialize_ravenscar): Fix copy/paste typo
        in name of "show ravenscar" prefix command name.

Add missing \n in `show ravenscar task-switching' output

A new-line was missing at the end of the output of the `show ravenscar
task-switching' command.  For instance:

    (gdb) show ravenscar task-switching
    Support for Ravenscar task/thread switching is enabled(gdb)

This patch fixes it.

gdb/ChangeLog:

        * ravenscar-thread.c (show_ravenscar_task_switching_command):
        Add missing '\n' in output.

[Ada/ravenscar] New name for active-thread symbol

The GNAT Ravenscar implementation has recently been enhanced to allow
programs using that runtime to run on multi-cpu systems.  One of the
changes that were made is that the name of the symbol we use to
determine which task is the currently-running task has changed.

This patch enhances the debugger to use the new name, and fallback on
the old name if not found (this is for compatibility with older versions
of the compiler/runtime).

gdb/ChangeLog:

        * ravenscar-thread.c (running_thread_name): Change value.
        (read_thread_id): Remove advance declaration.
        (get_running_thread_msymbol): New function.
        (has_ravenscar_runtime): Use get_running_thread_msymbol to
        compute msym_running_thread.
        (get_running_thread_id): Renames read_thread_id. Slight modifications
        to not take any argument anymore, using get_running_thread_msymbol
        to determine which symbol to use instead.
        (ravenscar_running_thread): Use get_running_thread_id instead of
        read_thread_id.

Move ChangeLog entry to the correct ChangeLog file.

bfd: bfin: drop needless symbol flag handling imported from FRV

The Blackfin bfd merged some FRV code recently, and then removed pieces
that didn't make sense.  In the FRV code, it outputs a "_gp" symbol in
its BFD whereas in the Blackfin code, we don't.  So while on the FRV
side it fiddles with the "flags" variable (sometimes using it for section
flags and sometimes using it for symbol flags), we don't need any of
that.  This lead to BZ 12177 where the Blackfin code is a bit confusing.
So to fix things up, remove more stuff we don't need.  Shouldn't change
the behavior at all.
