Subject: [Qemu-devel] [PULL v2 11/20] translate-all: define and use DEBUG_TB_FLUSH_GATE
Date: Tue, 10 Oct 2017 12:29:54 -0700 [thread overview]
Message-ID: <20171010193003.28857-12-richard.henderson@linaro.org> (raw)
In-Reply-To: <20171010193003.28857-1-richard.henderson@linaro.org>
From: "Emilio G. Cota" <cota@braap.org>
This gets rid of some ifdef checks while ensuring that the debug code
is compiled, which prevents bit rot.
