Subject: Remove unused td_ta_map_id2thr code
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1c56a84d9bac1f6a451a89d2c6af3d7078c4290e;p=binutils-gdb.git

Remove unused td_ta_map_id2thr code

linux-thread-db.c initializes td_ta_map_id2thr but never uses it.
This commit removes this dead code.

gdb/ChangeLog:

	* linux-thread-db.c (struct thread_db_info)
	<td_ta_map_id2thr_p>: Remove field.
	(try_thread_db_load_1): Remove initialization for the above.
