Subject: [Qemu-devel] [PATCH v3 06/16] tcg/arm: Fold away "noaddr" branch routines
Date: Fri, 30 Nov 2018 13:52:11 -0800	[thread overview]
Message-ID: <20181130215221.20554-7-richard.henderson@linaro.org> (raw)
In-Reply-To: <20181130215221.20554-1-richard.henderson@linaro.org>

There are one use apiece for these.  There is no longer a need for
preserving branch offset operands, as we no longer re-translate.
