Fix line walker to check whether a given DIE is CU or not.
Actually this function accepts CU, subprogram and inlined_subroutine
DIEs.
Without this fix, perf probe always fails to analyze lines on inlined
functions;
$ perf probe -L pre_schedule
Debuginfo analysis failed. (-2)
Error: Failed to show lines. (-2)
This fixes that bug, as below.
$ perf probe -L pre_schedule
<pre_schedule@/home/mhiramat/ksrc/linux-2.6/kernel/sched.c:0>
0 static inline void pre_schedule(struct rq *rq, struct task_struct *prev
{
2 if (prev->sched_class->pre_schedule)
3 prev->sched_class->pre_schedule(rq, prev);
}
/* rq->lock is NOT held, but preemption is disabled */
Changes from v1:
- Update against current tip tree.(Fix dwarf-aux.c)
