Subject: [PATCH 4/7] target/i386: TCG supports 32-bit SYSCALL
Date: Sun, 18 Jun 2023 23:51:11 +0200	[thread overview]
Message-ID: <20230618215114.107337-5-pbonzini@redhat.com> (raw)
In-Reply-To: <20230618215114.107337-1-pbonzini@redhat.com>

TCG supports both 32-bit and 64-bit SYSCALL, so expose it
with "-cpu max" even for 32-bit emulators.
