Subject: [Qemu-devel] [PULL for-3.0 1/1] tcg/i386: Mark xmm registers call-clobbered
Date: Mon, 23 Jul 2018 10:23:11 -0700 [thread overview]
Message-ID: <20180723172311.11316-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20180723172311.11316-1-richard.henderson@linaro.org>
When host vector registers and operations were introduced, I failed
to mark the registers call clobbered as required by the ABI.
Fixes: 770c2fc7bb7
