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, ^~~~~~~~~~~~~~~ 1 error generated.
