From f6223dbb50b5d8780df633633adf0742c662173d Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 4 May 2017 14:43:34 +0100 Subject: [PATCH] make_cleanup_restore_current_thread: Look up thread earlier The unconditional is_stopped call already asserts that the thread exists. gdb/ChangeLog: 2017-05-04 Pedro Alves * thread.c (make_cleanup_restore_current_thread): Move find_thread_ptid call before the is_stopped call. Assert that the thread is found. Replace is_stopped call by checking the thread's state directly. Remove unnecessary NULL-thread check. --- gdb/ChangeLog | 7 +++++++ gdb/thread.c | 10 +++++----- 2 files changed, 12 insertions(+), 5 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index aeb83dd..7c48c3d 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,12 @@ 2017-05-04 Pedro Alves + * thread.c (make_cleanup_restore_current_thread): Move + find_thread_ptid call before the is_stopped call.
