Subject: [PULL 25/25] target/i386: Use only 16 and 32-bit operands for IN/OUT
Date: Tue, 15 Oct 2024 16:17:11 +0200	[thread overview]
Message-ID: <20241015141711.528342-26-pbonzini@redhat.com> (raw)
In-Reply-To: <20241015141711.528342-1-pbonzini@redhat.com>

From: Richard Henderson <richard.henderson@linaro.org>

The REX.W prefix is ignored for these instructions.
Mirror the solution already used for INS/OUTS: X86_SIZE_z.
