From 86f2552bbd0e17b19bb5e9881042533eaea553c7 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Mon, 17 May 2010 10:00:05 +0200 Subject: [S390] add breaking event address for user space Copy the last breaking event address from the lowcore to a new field in the thread_struct on each system entry. Add a new ptrace request PTRACE_GET_LAST_BREAK and a new utrace regset REGSET_LAST_BREAK to query the last breaking event. This is useful for debugging wild branches in user space code.
