From c6b5da093a8ba740b71dd0052f3846016986fd21 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Thu, 20 Sep 2018 16:00:47 +0300 Subject: perf intel-pt: Add decoder flags for trace begin / end Previously, the decoder would indicate begin / end by a branch from / to zero. That hides useful information, in particular when a trace ends with a call. To prepare for remedying that, add Intel PT decoder flags for trace begin / end and map them to the existing sample flags.
