Subject: [Qemu-devel] [PATCH v3 06/14] tcg: Allow non-constant control macros
Date: Wed, 3 Jul 2013 14:29:20 -0700 [thread overview]
Message-ID: <1372886968-17497-7-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1372886968-17497-1-git-send-email-rth@twiddle.net>
This allows TCG_TARGET_HAS_* to be a variable rather than a constant,
which allows easier support for differing ISA levels for the host.
