From 051a01b9a2c1c1ef3049973a43d9ed4ddcc946f3 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 25 Sep 2015 16:15:43 +0300 Subject: [PATCH] perf inject: Set branch stack feature flag when synthesizing branch stacks The branch stack feature flag is set by 'perf record' when recording data that contains branch stacks. Consequently, when 'perf inject' synthesizes branch stacks, the feature flag should be set also.
