Fix to call convert_variable() if previous call does not fail.
To call convert_variable, it ensures "ret" is 0. However, since
"ret" has the return value of synthesize_perf_probe_arg() which
always returns positive value if it succeeded, perf probe doesn't
call convert_variable(). This will cause a SEGV when we add an
event with arguments.This has to be fixed as it ensures "ret" is greater than 0
(or not negative).This regression has been introduced by my previous patch, f182e3e1.

gcc 4.6 generates a concrete out-of-line instance when there is a
function which is implicitly inlined somewhere but also has its own
instance. The concrete out-of-line instance means that it has an
abstract origin of the function which is referred by not only
inlined-subroutines but also a concrete subprogram.Since current dwarf_func_inline_instances() can find only instances of
inlined-subroutines, this introduces new die_walk_instances() to find
both of subprogram and inlined-subroutines.e.g. without this,

Fix perf probe to search local variables in appropriate local inlined
function scope. For example, pre_schedule() has only 2 local variables,
as below;$ perf probe -L pre_schedule
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);
}However, current perf probe shows 4 local variables on pre_schedule(),
because it searches variables in the caller(schedule()) scope.$ perf probe -V pre_schedule
Available variables at pre_schedule
@
int cpu
long unsigned int* switch_count
struct rq* rq
struct task_struct* prevThis patch fixes this issue by searching variables in the local scope of
the instance of inlined function. Here is the result.$ perf probe -V pre_schedule

Fix a bug showing incorrect line number when a probe is put on the head of an
inline function. This patch updates find_perf_probe_point() and introduces new
rules to get correct line number.- If debuginfo doesn't have a correct file name, we shouldn't return line
number too, because, without file name, line number is meaningless.- If the address is in a function, it stores the function name and the offset
from the function entry.- If the address is on a line, it tries to get the relative line number from
the function entry line, except for the address is same as the entry
address of the function (in this case, the relative line number should
be 0).- If the address is in an inline function entry (call-site), it uses the
inline function call line number as the line on which the address is.- If the address is in an inline function body, it stores the inline
function name and offset from the inline function call site instead of the
(non-inlined) function.Cc: 2nddept-manager@sdl.hitachi.co.jp

Newer compilers (gcc 4.6) complains about:
return ret < 0 ?: 0;
For the following reason:
util/probe-finder.c: In function ‘probe_point_lazy_walker’:
util/probe-finder.c:1331:18: error: the omitted middle operand in ?: will always be ‘true’, suggest explicit middle operand [-Werror=parentheses]And indeed the return value is a somewhat obscure (but correct) value
of 'true', so return 'ret' instead - this is cleaner and unconfuses
GCC as well.Cc: Arnaldo Carvalho de Melo

While fixing an error propagating problem in f809b25 I added two
redundant checks.I did that because I didn't expect the checks to be on the while and for
loop condition expression, where they are tested before we run the loop,
where the 'ret' variable is set.So remove it from there and leave it just after it is actually set,
eliminating unneded tests.Reported-by: Masami Hiramatsu

There are two hunks in this patch that stops probe processing as soon as one
error is found, breaking out of loops, the other fix an error propagation that
should return a negative error number but instead was returning the result of
"ret < 0", which is 1 and thus made several error checks fail because they test
agains < 0.The problem could be triggered by asking for a variable that was optimized out,
fact that should stop the whole probe processing but instead was segfaulting
while installing broken probes:[root@emilia ~]# probe perf_mmap:55 user_lock_limit
Failed to find the location of user_lock_limit at this address.
Perhaps, it has been optimized out.
Failed to find 'user_lock_limit' in this function.
