From 571766010ea6bf9726b288eb2db1abb59b1841af Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 27 Nov 2018 10:46:34 +0200 Subject: [PATCH] perf auxtrace: Alter addr_filter__entire_dso() to work if there are no symbols addr_filter__entire_dso() uses the first and last symbols from a dso, and so does not work when there are no symbols. Alter it to filter the whole file instead.
