And do it for forward jumps as well. Loop detection requires more code to follow the flow control, etc. Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-soahcn1lz2u4wxj31ch0594j@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

Here is part of the new __list_del_entry() annotation: __list_del_entry 8.47 │ push %rbp 8.47 │ mov (%rdi),%rdx 20.34 │ mov $0xdead000000100100,%rcx 3.39 │ mov 0x8(%rdi),%rax 0.00 │ mov %rsp,%rbp 1.69 │ cmp %rcx,%rdx 0.00 │ je 43 1.69 │ mov $0xdead000000200200,%rcx 3.39 │ cmp %rcx,%rax 0.00 │ je a3 5.08 │ mov (%rax),%r8 18.64 │ cmp %r8,%rdi 0.00 │ jne 84 1.69 │ mov 0x8(%rdx),%r8 25.42 │ cmp %r8,%rdi 0.00 │ jne 65 1.69 │ mov %rax,0x8(%rdx) 0.00 │ mov %rdx,(%rax) 0.00 │ leaveq 0.00 │ retq 0.00 │ 43: mov %rdx,%r8 0.00 │ mov %rdi,%rcx 0.00 │ mov $0xffffffff817cd6a8,%rdx 0.00 │ mov $0x31,%esi 0.00 │ mov $0xffffffff817cd6e0,%rdi 0.00 │ xor %eax,%eax 0.00 │ callq ffffffff8104eab0 <warn_slowpath_fmt> 0.00 │ leaveq 0.00 │ retq 0.00 │ 65: mov %rdi,%rcx 0.00 │ mov $0xffffffff817cd780,%rdx 0.00 │ mov $0x3a,%esi 0.00 │ mov $0xffffffff817cd6e0,%rdi 0.00 │ xor %eax,%eax 0.00 │ callq ffffffff8104eab0 <warn_slowpath_fmt> 0.00 │ leaveq 0.00 │ retq The infrastructure is there to provide formatters for any instruction, like the one I'll do for call functions to elide the address. Further fixes on top of the first iteration: - Sometimes a jump points to an offset with no instructions, make the mark jump targets function handle that, for now just ignoring such jump targets, more investigation is needed to figure out how to cope with that. - Handle jump targets that are outside the function, for now just don't try to draw the connector arrow, right thing seems to be to mark this jump with a -> (right arrow) and handle it like a callq.

This allows comparing performance of different applications with each other. Previously, the sample count was displayed against an 'Events:' heading. With this patch, the header now reads (for example): Samples: 5K of event 'instructions' Event count (approx.): 2993026545 The patch covers both the stdio and the browser interface.
