Subject: [PATCH 11/12] perf, tools: Support sorting by intx, abort branch flags v2
From: Andi Kleen <ak@...ux.intel.com>
Extend the perf branch sorting code to support sorting by intx
or abort qualifiers. Also print out those qualifiers.
This also fixes up some of the existing sort key documentation.
We do not support notx here, because it's simply not showing
the intx flag.
v2: Readd flags to man pages
Signed-off-by: Andi Kleen <ak@...ux.intel.com>
