Subject: [PATCH v2 33/57] include/qemu/int128.h: Add function to create Int128 from int64_t
Date: Mon, 14 Jun 2021 16:09:43 +0100	[thread overview]
Message-ID: <20210614151007.4545-34-peter.maydell@linaro.org> (raw)
In-Reply-To: <20210614151007.4545-1-peter.maydell@linaro.org>

int128_make64() creates an Int128 from an unsigned 64 bit value; add
a function int128_makes64() creating an Int128 from a signed 64 bit
value.
