Subject: [PATCH 5.4 26/50] lib/mpi: Fix building for powerpc with clang
Date: Fri, 8 May 2020 14:35:32 +0200 [thread overview]
Message-ID: <20200508123047.011158803@linuxfoundation.org> (raw)
In-Reply-To: <20200508123043.085296641@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").
