Subject: [kvm-unit-tests PATCH 1/3] x86: emulator: use "SSE2" for the target
Date: Thu, 10 Oct 2019 11:35:04 -0700	[thread overview]
Message-ID: <20191010183506.129921-2-morbo@google.com> (raw)
In-Reply-To: <20191010183506.129921-1-morbo@google.com>

The movdqu and movapd instructions are SSE2 instructions. Clang
interprets the __attribute__((target("sse"))) as allowing SSE only
instructions. Using SSE2 instructions cause an error.
