Subject: [PATCH 04/18] perf session: Fix DEBUG=1 build with clang
Date: Mon, 20 Feb 2017 16:08:25 -0300	[thread overview]
Message-ID: <20170220190839.3928-5-acme@kernel.org> (raw)
In-Reply-To: <20170220190839.3928-1-acme@kernel.org>

From: Arnaldo Carvalho de Melo <acme@redhat.com>

The struct branch_stack->branch_stack.cycles field is a u64 :16
bitfield, and this somehow confuses clang 4.0 when checking the
arguments of a printf format, so cast the :16 to unsigned short to help
it.

Silences this:

  util/session.c:935:4: error: format specifies type 'unsigned short' but the argument has type 'u64' (aka 'unsigned long') [-Werror,-Wformat]
                          e->flags.cycles,
                          ^~~~~~~~~~~~~~~
