Can you supply a preprocessed source of sched.c and the options which you
compiled it with?

------- Comment #4 from pinskia at gcc dot gnu dot org 2006-11-12 08:35 -------
The only thing left from __task_rq_lock is a label.
If we look at that inlined function, we see:
static inline __attribute__((always_inline)) struct rq *__task_rq_lock(struct
task_struct *p)
{
struct rq *rq;
repeat_lock_task:
rq = (&(*((void)((task_cpu(p))), &per_cpu__runqueues)));
do { do { } while (0); (void)0; (void)(&rq->lock); } while (0);
if (__builtin_expect(!!(rq != (&(*((void)((task_cpu(p))),
&per_cpu__runqueues)))), 0)) {
do { do { } while (0); (void)0; (void)(&rq->lock); } while (0);
goto repeat_lock_task;
}
return rq;
}
the if is never true as rq is always equal to &per_cpu__runqueues. The calls to
task_cpu were inlined and we constant proped the value of rq the first of the
way through the function which we inlined this to.

OK, I thought that this was due to something like what you described, even not
knowing that much about gcc internals, but I thought that even in this case the
DW_TAG_inlined_subroutine would be emitted, or hoped to as it would allow me to
do what I want with my tools :-\

There is nothing to emit debug info about, so we don't.

Well, at least gcc emits this:
<1><a2f2>: Abbrev Number: 65 (DW_TAG_subprogram)
DW_AT_sibling : <a324>
DW_AT_name : (indirect string, offset: 0x4515): __task_rq_lock
DW_AT_decl_file : 1
DW_AT_decl_line : 378
DW_AT_prototyped : 1
DW_AT_type : <9a2f>
DW_AT_inline : 3 (declared as inline and inlined)
But no DW_TAG_inlined_subroutine, as we've been discussing:
[acme@newtoy net-2.6.20]$ readelf -wi ../OUTPUT/qemu/net-2.6.20/kernel/sched.o
| grep a2f2
DW_AT_sibling : <a2f2>
<1><a2f2>: Abbrev Number: 65 (DW_TAG_subprogram)
[acme@newtoy net-2.6.20]$

I'm quite aware of what GCC outputs here :)
However, past the initial declarations, we don't output debug
information about what the state of the IR is at random points in the
compilation, only about what the final output looks like. Since there
is no inlined code left, we don't end up saying there is an inlined
subroutine.
Even if we could change this, i'm not sure we'd want to. It doesn't
seem incorrect at all to do what we do.
Otherwise, you'd end up with inlined subroutine dies with no low
pc/high pc associated with them, which seems nonsensical.

OK, so I'll have to find another way of using the DWARF info to see if a inline
routine, such as __task_rq_lock was used at all in the build or was just
included in the DWARF info but not referenced anywhere, have to dig more into
the available information...
BTW, if, in these cases, DW_TAG_subroutine is not referenced, what is the
purpose of it being included? Is there a reason my limited knowledge is not
realising?

Well, it is referenced. It did exist in the source, and was inlined.
That's what we output. DW_TAG_subprogram with no PC range is actually
common.
Because all the inlined instances were optimized away, there are no
DW_TAG_inlined_* entries for them.

/me slaps himself in the face
Duh, should have checked this :-)
[acme@newtoy examples]$ cat a.c
static inline int foo(int i)
{
return i + 10;
}
int main(void)
{
}
[acme@newtoy examples]$ readelf -wi a |grep foo
[acme@newtoy examples]$
Excellent, only if its not static:
[acme@newtoy examples]$ cat a.c
inline int foo(int i)
{
return i + 10;
}
int main(void)
{
}
[acme@newtoy examples]$ readelf -wi a |grep foo
DW_AT_name : foo
[acme@newtoy examples]$
And in this case my tool, prefcnt, should warn that this routine, inline or
not, is not being used at all and is eligible to go to the dustbin.
Thanks a lot for your patience and advise, closing the ticket as INVALID.
