      perf annotate browser: Initial loop detection · a3f895be
      Arnaldo Carvalho de Melo authored
      Simple algorithm, just look for the next backward jump that points to
      before the cursor.
      
      Then draw an arrow connecting the jump to its target.
      
      Do this as you move the cursor, entering/exiting possible loops.
      
      Ex (graph chars replaced to avoid mail encoding woes):
      
      avc_has_perm_flags
          0.00 |         nopl   0x0(%rax)
          5.36 |+-> 68:  mov    (%rax),%rax
          5.15 ||        test   %rax,%rax
          0.00 ||      v je     130
          2.96 ||   74:  cmp    -0x20(%rax),%ebx
         47.38 ||        lea    -0x20(%rax),%rcx
          0.28 ||      ^ jne    68
          3.16 ||        cmp    -0x18(%rax),%dx
          0.00 |+------^ jne    68
          4.92 |         cmp    0x4(%rcx),%r13d
          0.00 |       v jne    68
          1.15 |         test   %rcx,%rcx
          0.00 |       v je     130

      Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
      
      Fixes and improvements for perf/core:
      
      . Overhaul the tools/ makefiles, gluing them to the top level Makefile, from
        Borislav Petkov.
      
      . Move the UI files from tools/perf/util/ui/ to tools/perf/ui/. Also move
        the GTK+ browser to tools/perf/ui/gtk/, from Namhyung Kim.
      
      . Only fallback to sw cycles counter on ENOENT for the hw cycles, from
        Robert Richter
      
      . Trivial fixes from Robert Richter
      
      . Handle the autogenerated bison/flex files better, from Namhyung and Jiri Olsa.
      
      . Navigate jump instructions in the annotate browser, just press enter or ->,
        still needs support for a jump navigation history, i.e. to go back.
      
      . Search string in the annotate browser: same keys as vim:
           / forward
           n next backward/forward
           ? backward
      
      . Clarify number of events/samples in the report header, from Ashay Rane
