When the jump instruction is displayed at the row 0 in annotate view, the arrow is broken. An example: 16.86 │ ┌──je 82 0.01 │ movsd (%rsp),%xmm0 │ movsd 0x8(%rsp),%xmm4 │ movsd 0x8(%rsp),%xmm1 │ movsd (%rsp),%xmm3 │ divsd %xmm4,%xmm0 │ divsd %xmm3,%xmm1 │ movsd (%rsp),%xmm2 │ addsd %xmm1,%xmm0 │ addsd %xmm2,%xmm0 │ movsd %xmm0,(%rsp) │82: sub $0x1,%ebx 83.03 │ ↑ jne 38 │ add $0x10,%rsp │ xor %eax,%eax │ pop %rbx │ ← retq The patch increments the row number before checking with 0.
