Subject: [PATCH] ARM:alignment:correct variable type of nr_regs
Date: Sun, 5 Jan 2020 10:17:36 +0800 [thread overview]
Message-ID: <1578190656-19270-1-git-send-email-hanterliu@gmail.com> (raw)
From: hanter Liu <hanterliu@gamil.com>
if ldmstm instruction U bit is unset, nr_regs
should be negative value, so change variable
type of nr_regs from unsigned int to int.
