efae1d9244 Minor comment reformatting in generic_elf_osabi_sniffer
Comment says it all.  I just felt that putting some new text in
a separate paragraph allowed us to clearly identify the section
about ELFOSABI_NONE, and the part that talks about the new
ELFOSABI_GNU.

gdb/ChangeLog:

        * osabi.c (generic_elf_osabi_sniffer): Minor comment reformatting.

6040a59db5 ada-tasks.c: handle known tasks maintained by a simply-linked list.
The mapping between Ada tasks, and the underlying threads is
normally maintained by the GNAT runtime under the known_tasks
array.  For performance reasons, this array is just a static
array with 10_000 entries in it. However, this is not very
practical in certain environments where memory is limited.
For those environments, the runtime has been enhanced to use
an alternate scheme with a linked list.

This change enhances the Ada tasking support to recognize this
situation and use the correct way of reading the tasks info
based on the the situation.

gdb/ChangeLog  (Tristan Gingold)

	* ada-tasks.c (KNOWN_TASKS_LIST): New macro.
	(tcb_fieldno): Add activation_link field.
	(get_known_tasks_addr): Moved and rewritten.
	(get_tcb_types_info): Set activation_link field.
	(read_known_tasks_array): Add parameter.  Rewritten.
	(read_known_tasks_list): New function.
	(read_known_tasks): New function.
	(ada_build_task_list): Call read_known_tasks instead of
	read_known_tasks_array.
	* ravenscar-thread.c: Add first_task_name constant.
	(has_ravenscar_runtime): Check for task list too.
