Subject: [PULL v2 07/12] qemu/int128: Re-shuffle Int128Alias members
Date: Wed, 3 May 2023 08:20:59 +0100 [thread overview]
Message-ID: <20230503072221.1746802-15-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230503072221.1746802-1-richard.henderson@linaro.org>
Clang 14, with --enable-tcg-interpreter errors with
include/qemu/int128.h:487:16: error: alignment of field 'i' (128 bits)
does not match the alignment of the first field in transparent union;
transparent_union attribute ignored [-Werror,-Wignored-attributes]
__int128_t i;
^
include/qemu/int128.h:486:12: note: alignment of first field is 64 bits
Int128 s;
^
1 error generated.
By placing the __uint128_t member first, this is avoided.
