Subject: [PATCH for-3.0] tcg/i386: Mark xmm registers call-clobbered
Date: Sun, 22 Jul 2018 18:29:41 -0700
Message-Id: <20180723012941.16920-1-richard.henderson@linaro.org>
X-Mailer: git-send-email 2.17.1
When host vector registers and operations were introduced, I failed
to mark the registers call clobbered as required by the ABI.
Fixes: 770c2fc7bb7
