Subject: [PATCH] pass constants as first argument to st_mult()
From: René_Scharfe <l.s.r () web ! de>
Date: 2016-07-30 18:18:31
Message-ID: 579CEF77.9070202 () web ! de
[Download RAW message or body]
The result of st_mult() is the same no matter the order of its
arguments. It invokes the macro unsigned_mult_overflows(), which
divides the second parameter by the first one. Pass constants
first to allow that division to be done already at compile time.
