Subject: [PATCH 7/8] show_progress: change HASHES_PER_LINE from 65 to 64 to avoid division
Date: Tue, 16 Feb 2021 21:02:07 +0100 [thread overview]
Message-ID: <20210216200208.5275-8-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210216200208.5275-1-a.fatoum@pengutronix.de>
Decreasing the progress bar length by one won't change visuals much,
but will allow the compiler to optimize a multiplication and a modulo
into bitwise operations.
