From 37ee93a974c49ab9edfcd1db0aad3838b0395b14 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Thu, 29 Nov 2018 13:13:59 -0800 Subject: [PATCH] tcg/arm: Fold away "noaddr" branch routines MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There are one use apiece for these. There is no longer a need for preserving branch offset operands, as we no longer re-translate.
