Subject: [PATCH 2/3] perf: Support setting the disassembler style
From: Andi Kleen <ak@...ux.intel.com>
Add -M option to report/annotate to pass directly to objdump.
This allows to use -M intel for intel style disassembler syntax,
which is useful for people who are very used to the Intel syntax.
Signed-off-by: Andi Kleen <ak@...ux.intel.com>
