Subject: [PATCH 4.14 15/22] lib/mpi: Fix building for powerpc with clang
Date: Fri,  8 May 2020 14:35:27 +0200	[thread overview]
Message-ID: <20200508123035.757505988@linuxfoundation.org> (raw)
In-Reply-To: <20200508123033.915895060@linuxfoundation.org>

From: Nathan Chancellor <natechancellor@gmail.com>

[ Upstream commit 5990cdee689c6885b27c6d969a3d58b09002b0bc ]

0day reports over and over on an powerpc randconfig with clang:

lib/mpi/generic_mpih-mul1.c:37:13: error: invalid use of a cast in a
inline asm context requiring an l-value: remove the cast or build with
-fheinous-gnu-extensions

Remove the superfluous casts, which have been done previously for x86
and arm32 in commit dea632cadd12 ("lib/mpi: fix build with clang") and
commit 7b7c1df2883d ("lib/mpi/longlong.h: fix building with 32-bit
x86").
