Subject: [PATCH 4/5] lib/mpi: Fix for building for MIPS64 with Clang
Date: Sun, 11 Aug 2019 20:31:19 -0700 [thread overview]
Message-ID: <20190812033120.43013-5-natechancellor@gmail.com> (raw)
In-Reply-To: <20190812033120.43013-1-natechancellor@gmail.com>
From: Werner Koch <wk@gnupg.org>
* mpi/longlong.h [MIPS64][__clang__]: Use the C version like we
already do for 32 bit MIPS
clang errors:
lib/mpi/generic_mpih-mul1.c:37:24: error: invalid use of a cast in a
inline asm context requiring an l-value: remove the cast or build with
-fheinous-gnu-extensions
umul_ppmm(prod_high, prod_low, s1_ptr[j], s2_limb);
~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
lib/mpi/longlong.h:652:20: note: expanded from macro 'umul_ppmm'
: "=l" ((USItype)(w0)), \
~~~~~~~~~~^~~
lib/mpi/generic_mpih-mul1.c:37:3: error: invalid output constraint '=h'
in asm
umul_ppmm(prod_high, prod_low, s1_ptr[j], s2_limb);

lib/mpi/longlong.h:653:7: note: expanded from macro 'umul_ppmm'
"=h" ((USItype)(w1)) \
