Subject: [PATCH] sparc: Fix broken memset for sparc32 [BZ #31068]
Date: Wed, 15 Nov 2023 13:29:43 +0100	[thread overview]
Message-ID: <20231115122943.22799-1-ludwig.rydberg@gaisler.com> (raw)

From: Andreas Larsson <andreas@gaisler.com>

Fixes commit a61933fe27df ("sparc: Remove bzero optimization") that
after moving code jumped to the wrong label 4.

Verfied by successfully running string/test-memset on sparc32.
