From 73fce314dbbf2d1c3cd411a34535ebe5d20e1e45 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Tue, 29 Jun 2021 11:01:05 -0700 Subject: target/arm: Use DISAS_TOO_MANY for ISB and SB Using gen_goto_tb directly misses the single-step check. Let the branch or debug exception be emitted by arm_tr_tb_stop.
