Subject: [RFC PATCH 3/4] sh: define __BIG_ENDIAN for math-emu
Date: Wed, 2 Jun 2021 16:14:42 -0700 [thread overview]
Message-ID: <20210602231443.4670-3-rdunlap@infradead.org> (raw)
In-Reply-To: <20210602231443.4670-1-rdunlap@infradead.org>
The headers in include/math-emu/ test for __BYTE_ORDER == __BIG_ENDIAN
without checking to see if these macros are defined, so add
a define for __BIG_ENDIAN before pulling in these headers.
This placates these build warnings:
In file included from ../arch/sh/math-emu/math.c:23:
../include/math-emu/single.h:50:21: warning: "__BIG_ENDIAN" is not defined, evaluates to 0 [-Wundef]
50 | #if __BYTE_ORDER == __BIG_ENDIAN
In file included from ../arch/sh/math-emu/math.c:24:
../include/math-emu/double.h:59:21: warning: "__BIG_ENDIAN" is not defined, evaluates to 0 [-Wundef]
59 | #if __BYTE_ORDER == __BIG_ENDIAN
Fixes: 4b565680d163 ("sh: math-emu support")
