Subject: [LTP] [PATCH v2] stime: Only o32 system calls require 32-bit programs on mips
Date: Tue, 20 Jul 2021 16:37:08 +0800	[thread overview]
Message-ID: <20210720083708.13281-1-zhanglianjie@uniontech.com> (raw)

The stime() system call is only o32, not n32 and n64. If you do not
specify that the current program is compiled to 32-bit when compiling
the program on mips, the stime() system call will fail when the
program is running.
