Subject: [Qemu-devel] [PULL 11/23] translate-all: define and use DEBUG_TB_FLUSH_GATE
Date: Mon,  9 Oct 2017 17:55:48 -0700	[thread overview]
Message-ID: <20171010005600.28735-12-richard.henderson@linaro.org> (raw)
In-Reply-To: <20171010005600.28735-1-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.
