From a19b4a14053f24e2df93b6bcc72ed1086cce0de4 Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Thu, 1 Mar 2007 10:37:35 +0100 Subject: [PATCH] [AVR32] Fix bogus ti->flags manipulation in debug handler We should OR in a bitmask, not a bit offset, into ti->flags. This might fix some strange behaviour when single stepping. Also, use set_ti_thread_flag() to manipulate the flags to avoid surprises in the future.
