Subject: [PATCH 09/14] nds32: define syscall_get_arch()
Date: Wed, 27 Feb 2019 18:30:51 +0300 [thread overview]
Message-ID: <20190227153051.GE23744@altlinux.org> (raw)
In-Reply-To: <20190109124320.GI11981@altlinux.org>
syscall_get_arch() is required to be implemented on all architectures
in addition to already implemented syscall_get_nr(),
syscall_get_arguments(), syscall_get_error(), and
syscall_get_return_value() functions in order to extend the generic
ptrace API with PTRACE_GET_SYSCALL_INFO request.
