To\r\nmake these files' symbols more useful for the dynamic linker, the section offset\r\n(file interpretation) gives way to a virtual address (memory interpretation) for\r\nwhich the section number is irrelevant.\r\n```\r\n\r\nThis is a problem in practice as well. I run into this while tracing shared\r\nlibraries on Android with bpftrace. Some of them have text sections mmapped\r\nat different offset than file offset which results in probes being placed\r\nat wrong offsets.ghprbCommentBody[buildbot, test this please]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="Translate virtual addresses to binary addresses for shared libs as well." href="https://github.com/iovisor/bcc/pull/2840">PR #2840</a>: Translate virtual addresses...#41115211217460664bcc-pr #411411false4113303SUCCESS1585203760730https://buildbot.iovisor.org/jenkins/user/ethercflow/my-views/view/all/job/bcc-pr/411/git411https://buildbot.iovisor.org/jenkins/user/ethercflow/my-views/view/all/job/bcc-pr/label=fc25/411/411https://buildbot.iovisor.org/jenkins/user/ethercflow/my-views/view/all/job/bcc-pr/label=fc26/411/411https://buildbot.iovisor.org/jenkins/user/ethercflow/my-views/view/all/job/bcc-pr/label=fc27/411/411https://buildbot.iovisor.org/jenkins/user/ethercflow/my-views/view/all/job/bcc-pr/label=fc28/411/411https://buildbot.iovisor.org/jenkins/user/ethercflow/my-views/view/all/job/bcc-pr/label=ubuntu1604/411/411https://buildbot.iovisor.org/jenkins/user/ethercflow/my-views/view/all/job/bcc-pr/label=ubuntu1710/411/411https://buildbot.iovisor.org/jenkins/user/ethercflow/my-views/view/all/job/bcc-pr/label=ubuntu1804/411/
