From fb29fa58e36df09c807d252247d64a221fcd5bbb Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 25 Apr 2012 14:16:03 -0300 Subject: perf annotate: Mark jump instructions with no offset I.e. jumps that go to code outside the current function, that is denoted in objdump -dS as: 399f877a9f: jne 399f87bcf4 <_L_lock_5154> I.e. without the + after the name of the current function, like in: 399f877aa5: jmp 399f877ab2 <_int_free+0x412> The browser will use that info to avoid drawing connectors to the start of the function, since ops.target.addr was zero.
