      tools lib traceevent: Handle INVALID_ARG_TYPE errno in pevent_strerror · 7a905611
      由 Arnaldo Carvalho de Melo 提交于 
      gcc on f14 32-bit rightly complains:

   tools/lib/traceevent/event-parse.c:5097:2: error: enumeration value ‘PEVENT_ERRNO__INVALID_ARG_TYPE’ not handled in switch

The entry for it is in the error strings array pevent_error_str[]:

        _PE(INVALID_ARG_TYPE,   "invalid argument type")

It was just not being handled on the pevent_strerror switch, fix it.

  tools/lib/traceevent/event-parse.c: In function ‘pevent_register_print_function’:
  tools/lib/traceevent/event-parse.c:5366:3: error: comparison of unsigned expression < 0 is always false

This is because:

          enum pevent_func_arg_type type;

this enum doesn't have any negative value, so gcc makes it an 'unsigned
int'. Fix it by removing the < 0 test.

      perf annotate: Merge same lines in summary view · 41127965
      由 Namhyung Kim 提交于 
      The --print-line option of perf annotate command shows summary for
each source line.  But it didn't merge same lines so that it can
appear multiple times.

To do that, introduce percent_sum field so that the normal

      perf annotate: Don't try to follow jump target on PLT symbols · 32ae1efd
      由 Namhyung Kim 提交于 
      The perf annotate browser on TUI can identify a jump target for a
selected instruction.  It assumes that the jump target is within the
function but it's not the case of PLT symbols which have offset out of
the function as a target.

Since it caused a segmentation fault, do not try to follow jump target
on the PLT symbols.

      perf test: fix a build error on builtin-test · 12f8f74b
      由 Zheng Liu 提交于 
      Recently I build perf and get a build error on builtin-test.c. The error is as
following:

make: *** [builtin-test.o] Error 1

This problem is introduced in 3e7c439a. CPU_ALLOC and related macros are
missing in sched__get_first_possible_cpu function. In 54489c18, commiter
mentioned that CPU_ALLOC has been removed. So CPU_ALLOC calls in this
function are removed to let perf to be built.

      perf hists: Introduce hists__link · 494d70a1
      由 Arnaldo Carvalho de Melo 提交于 
      That given two hists will find the hist_entries (buckets) in the second
hists that are for the same bucket in the first and link them, then it
will look for all buckets in the second that don't have a counterpart in
the first and will create a dummy counterpart that will then be linked
to the entry in the second.

For multiple events this will be done pairing the leader with all the
other events in the group, so that in the end the leader will have all
the buckets in all the hists in a group, dummy or not while the other
hists will be left untouched.
