Subject: [PATCH] i386: Remove unused file sysdeps/unix/i386/sysdep.S
Date: Thu, 28 May 2020 11:11:26 +0200 [thread overview]
Message-ID: <877dwwfmpt.fsf@oldenburg2.str.redhat.com> (raw)
Linux overrides this file via sysdeps/unix/sysv/linux/i386/sysdep.c.
Hurd does not have sysdeps/unix/i386 on its search path, so it uses
csu/sysdep.c instead.
