From 2e718e665706d5fcc3e3501bda26f277f055ed85 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 28 Jul 2023 10:22:52 -0700 Subject: [PATCH] target/ppc: Disable goto_tb with architectural singlestep MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The change to use translator_use_goto_tb went too far, as the CF_SINGLE_STEP flag managed by the translator only handles gdb single stepping and not the architectural single stepping modeled in DisasContext.singlestep_enabled.
