perf scripting perl: Fix compile error with some perl5 versions

2017-07-15T09:57:48+00:00

commit d7dd112ea5cacf91ae72c0714c3b911eb6016fea upstream.

Fix below compile error:

  CC       util/scripting-engines/trace-event-perl.o
  In file included from /usr/lib/perl5/5.22.2/i686-linux/CORE/perl.h:5673:0,
                   from util/scripting-engines/trace-event-perl.c:31:
  /usr/lib/perl5/5.22.2/i686-linux/CORE/inline.h: In function 'S__is_utf8_char_slow':
  /usr/lib/perl5/5.22.2/i686-linux/CORE/inline.h:270:5: error: nested extern declaration of 'Perl___notused' [-Werror=nested-externs]
          dTHX;   /* The function called below requires thread context */
			     ^
  cc1: all warnings being treated as errors

After digging perl5 repository, I find out that we will meet this
compile error with perl from v5.21.1 to v5.25.4

tools lib traceevent: Support function __get_dynamic_array_len

2015-09-02T19:30:46+00:00

Support helper function __get_dynamic_array_len() in libtraceevent, this
function is used accompany with __print_array() or __print_hex(), but
currently it is not an available function in the function list of
process_function().

The total allocated length of the dynamic array is embedded in the top
half of __data_loc_##item field. This patch adds new arg type
PRINT_DYNAMIC_ARRAY_LEN to return the length to eval_num_arg(),

tracing: Rename FTRACE_MAX_EVENT to TRACE_EVENT_TYPE_MAX

2015-05-13T18:06:42+00:00

The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. Rename the max trace_event type size to
something more descriptive and appropriate.

perf db-export: No need to have ->thread twice in struct export_sample

2015-04-02T16:18:43+00:00

As it comes from address_location->thread, that is already stored as
export_sample->al, where the thread can be obtained.

perf db-export: No need to pass thread twice to db_export__sample

2015-04-02T16:18:42+00:00

As it is available via another parameter, address_location->thread.

perf scripting: No need to pass thread twice to the scripting callbacks

2015-04-02T16:18:41+00:00

It is already in the addr_location, so remove the redundant 'thread'
parameter from the callback signatures.
