Hi Masami,
[root@zoo ~]# perf probe -x ~/bin/perf -L lock__delete
<lock__delete@/home/git/linux/tools/perf/util/annotate.c:0>
0 static void lock__delete(struct ins_operands *ops)
1 {
2 struct ins *ins = ops->locked.ins;
4 if (ins && ins->ops->free)
5 ins->ops->free(ops->locked.ops);
else
7 ins__delete(ops->locked.ops);
9 zfree(&ops->locked.ops);
10 zfree(&ops->target.raw);
11 zfree(&ops->target.name);
12 }
And:
[root@zoo ~]# pahole ~/bin/perf -C ins_operands
struct ins_operands {
char * raw; /* 0 8 */
struct {
char * raw; /* 8 8 */
char * name; /* 16 8 */
u64 addr; /* 24 8 */
u64 offset; /* 32 8 */
} target; /* 8 32 */
union {
struct {
char * raw; /* 40 8 */
char * name; /* 48 8 */
u64 addr; /* 56 8 */
} source; /* 24 */
struct {
struct ins * ins; /* 40 8 */
struct ins_operands * ops; /* 48 8 */
} locked; /* 16 */
}; /* 40 24 */
/* --- cacheline 1 boundary (64 bytes) --- */
/* size: 64, cachelines: 1, members: 3 */
};
[root@zoo ~]#
But:
[root@zoo ~]# perf probe -x ~/bin/perf lock__delete ops
'locked_ops=ops->locked.ops'
ops(type:ins_operands) has no member locked.
Error: Failed to add events.
[root@zoo ~]#
Yes, it has :-)
