From e04ee09e24563f013c35cdebd7e9de3092b99b83 Mon Sep 17 00:00:00 2001 From: Kevin Buettner Date: Wed, 4 May 2016 15:21:12 -0700 Subject: Add target method for converting thread handle to thread_info struct pointer This patch adds a target method named `to_thread_handle_to_thread_info'. It is intended to map a thread library specific thread handle (such as pthread_t for the pthread library) to the corresponding GDB internal thread_info struct (pointer). An implementation is provided for Linux pthreads; see linux-thread-db.c. gdb/ChangeLog: * target.h (struct target_ops): Add to_thread_handle_to_thread_info. (target_thread_handle_to_thread_info): Declare. * target.c (target_thread_handle_to_thread_info): New function. * target-delegates.c: Regenerate. * gdbthread.h (find_thread_by_handle): Declare. * thread.c (find_thread_by_handle): New function. * linux-thread-db.c (thread_db_thread_handle_to_thread_info): New function. (init_thread_db_ops): Register thread_db_thread_handle_to_thread_info. --- gdb/gdbthread.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'gdb/gdbthread.h') diff --git a/gdb/gdbthread.h b/gdb/gdbthread.h index fe7acc2c700..d5101ab9d09 100644 --- a/gdb/gdbthread.h +++ b/gdb/gdbthread.h @@ -448,6 +448,10 @@ extern struct thread_info *find_thread_ptid (ptid_t ptid); /* Find thread by GDB global thread ID. */ struct thread_info *find_thread_global_id (int global_id); +/* Find thread by thread library specific handle in inferior INF. */ +struct thread_info *find_thread_by_handle (struct value *thread_handle, + struct inferior *inf); + /* Finds the first thread of the inferior given by PID.
